Introduction This booklet has been prepared to help you understand more about non-Hodgkin lymphoma. This is also known as non-Hodgkin’s lymphoma or lymphatic cancer as it affects the lymph nodes. Many people feel understandably shocked and upset when told they have non-Hodgkin lymphoma. We hope this booklet will help you understand how the disease is diagnosed and treated. We cannot advise you what is the best treatment for you. You need to discuss this with your doctor. However, we hope this information will answer some of your questions and help you think about questions you may want to ask your doctor or other health carers. You may like to pass this booklet on to your family and friends for their information. This booklet does not need to be read from cover to cover – just read the parts that are useful to you. Some medical terms are defined in the glossary on page 54.

What is cancer? Cancer is a disease of the cells, which are the body’s basic building blocks. Our bodies constantly make new cells to help us grow, to replace worn-out cells and to heal damaged cells after an injury. Normally, cells multiply and die in an orderly way but sometimes something goes wrong with this process and cells grow in an uncontrolled way. This uncontrolled growth may cause blood or lymph fluid in the body to become abnormal, or form a lump called a tumour. A tumour can be benign or malignant. • Benign tumour – Cells are confined to one area and are not able to spread to other parts of the body. This is not cancer. • Malignant tumour – This is made up of cancerous cells, which have the ability to spread by travelling through the bloodstream or lymphatic system (lymph fluid). The cancer that first develops in a tissue or organ is called the primary cancer. A malignant tumour is usually named after the organ or type of cell affected. A tumour that has not spread to other parts of the body is called a localised cancer. A malignant tumour may invade deeper into surrounding tissue and can grow its own blood vessels (angiogenesis). With cancers that affect the blood and bone marrow, abnormal cells multiply in such a way that they crowd the bone marrow and reduce its ability to make normal blood cells. Sometimes the abnormal cells also clump together to form a tumour. 4 Cancer Council
If you have non-Hodgkin lymphoma, which is a type of blood cancer, the cancer cells usually affect and enlarge your lymph nodes at one or more lymph node sites around the body. The cancer cells can spread to any organ, in particular, the bone marrow, spleen and liver. Occasionally, it can spread to the brain and spinal cord. When cancer spreads it is called a secondary cancer, a metastasis or advanced cancer. A metastasis keeps the name of the original cancer. For example, non-Hodgkin lymphoma that has spread to the liver is still called non-Hodgkin lymphoma.

The lymphatic system Non-Hodgkin lymphoma is a cancer of the white blood cells that starts in the lymphatic system. The lymphatic system is a key part of the immune system, which helps protect the body against disease and infection. The lymphatic system includes a network of thin tubes (lymph vessels) found throughout the body, as well as organs, such as the spleen and thymus. Lymph vessels carry a clear fluid called lymph. This fluid travels to and from tissue in the body before being emptied into the bloodstream. Lymph contains white blood cells called lymphocytes, which help fight infection. The two main types of lymphocytes, B-cells and T-cells, are produced in the bone marrow. There is a network of small, bean-shaped structures called lymph nodes or glands along the lymph vessels. Lymph nodes are found throughout the body, including the neck, underarms, chest, abdomen and groin. When lymph nodes become swollen, it is a sign that your body is fighting infection. For example, glands in your neck may swell when you have a sore throat. Other parts of the lymphatic system include: • spleen – contains lymphocytes, filters waste products from the blood, and destroys old cells, abnormal cells and bacteria • thymus – a gland where lymphocytes develop and mature 6 Cancer Council
• tonsils – a collection of lymphatic tissue at the back of the throat that traps inhaled or ingested germs • bone marrow – the soft, spongy material inside bones that makes three types of blood cells: red blood cells (carry oxygen); white blood cells, including lymphocytes (fight infection); and platelets (help the blood to clot).

Key questions Q: What is non-Hodgkin lymphoma? A: Non-Hodgkin lymphoma is a type of lymphoma, which is a general term for cancers that develop in lymphatic tissue. Sometimes non-Hodgkin lymphoma is also called non-Hodgkin’s lymphoma. If you have non-Hodgkin lymphoma, your lymphocytes become damaged. They grow abnormally and multiply uncontrollably, causing your lymph nodes to enlarge and form painless lumps called tumours. As the abnormal lymphocytes replace the normal ones, your immune system becomes less effective. Non-Hodgkin lymphoma can occur in one lymph node, a group of lymph nodes or another organ. The disease can often be found in several parts of the body at the same time. Q: What types are there? A: There are many types of non-Hodgkin lymphoma. Several different systems have been used to classify these types. Non-Hodgkin lymphoma can be classified as slow growing (low grade) or fast growing (high-grade). See pages 21–22. More recent systems consider the type of cell affected (B-cells or T-cells), the genetic make-up of the cells (DNA chromosomes) and if certain proteins are present. B-cell lymphomas make up about 85% of all non-Hodgkin lymphomas. 8 Cancer Council
B-cell types of lymphoma diffuse large B-cell starts as a fast-growing lymph node tumour cells tend to grow in circular groups of cells, follicular called follicles, in the lymph nodes a slow-growing disease similar to chronic small lymphocytic lymphocytic leukaemia affects the outer edge of B-cells in the lymph mantle cell B-cell node follicle, can grow quickly (aggressive) T-cell types of lymphoma often occur as widespread, enlarged, painless peripheral T-cell lymph nodes in the neck, armpit or groin precursor can grow rapidly and interfere with breathing, T-lymphoblastic so it needs to be diagnosed and treated quickly Q: What are the causes? A: In most cases, the cause of non-Hodgkin lymphoma is unknown. Risk factors for developing the disease may include: • immune system deficiency – caused by infection such as human immunodeficiency virus (HIV), human T-lymphotrophic virus (HTLV-1), herpes virus 8 or Helicobacter pylori (H. pylori) • autoimmune diseases – such as rheumatoid arthritis • taking drugs that affect the immune system – some people take immuno-suppressant drugs after an organ transplant, for HIV or for an autoimmune disease. Key questions 9
Q: What are the symptoms? A: Non-Hodgkin lymphoma may cause different symptoms depending on where it is located in the body. These symptoms may include: • painless swelling of a lymph node (e.g. in the neck, underarm or groin) • unexplained and regular fevers • excessive sweating, particularly at night • unintentional weight loss • persistent tiredness and lethargy • itchy skin. Sometimes lymphoma starts in lymph nodes in deeper parts of the body, such as the abdomen (causing bloating) or the chest (causing coughing, discomfort and difficulty breathing). Symptoms of non-Hodgkin lymphoma are common to many illnesses, such as the flu or a virus. If you are concerned, make an appointment with your general practitioner (GP). Q: How common is it? A: About 4000 Australians are diagnosed with non-Hodgkin lymphoma each year. Most cases of non-Hodgkin lymphoma occur in adults aged 65 years and older. The risk of developing it increases as you get older. However, it can also occur in children and young adults. 10 Cancer Council
Diagnosis If your doctor suspects that you have lymphoma, you will have a physical examination to check your lymph nodes for swelling. Your doctor will examine your throat, tonsils, neck, abdomen, underarms and groin. Most people also have a biopsy, blood count and CT scan. Biopsy A diagnosis of lymphoma is made by removing the enlarged lymph node, or part of it, and examining the cells under a microscope. This is called a biopsy. It can be done in different ways: • Excision biopsy – You will be given a local or general anaesthetic, depending on the location of the lymph node. The doctor will cut through the skin to remove the whole node, then close the wound with temporary stitches. This is usually done as an outpatient procedure. However, if the nodes are deep, for example in the abdomen or chest, you may have to stay in hospital longer, usually for a few days. • Needle core biopsy – A needle is used to remove tissue from the lymph node. You will be given a local anaesthetic to numb the area. This procedure usually takes 30–60 minutes. • Fine needle biopsy – A thin needle is inserted to remove a small amount of tissue or fluid from the affected area/node in your body. This type of biopsy is uncommon because it doesn’t usually provide enough tissue for a full diagnosis. However, it may help to determine if you need another type of biopsy. Diagnosis 11
Further tests If the biopsy shows that you have non-Hodgkin lymphoma, you will then usually have a few of the tests described on the following pages. These tests will show whether cancer has spread to other parts of your body. This is called staging – see page 17. Blood tests Your doctor will take a sample of your blood to check how your kidney and liver are functioning. These organs may not work properly if you have lymphoma. Blood samples are also taken regularly during treatment to check your blood counts, which is a measure of the different levels of red blood cells, white blood cells and platelets. Low blood counts may indicate the non-Hodgkin lymphoma has spread to the bone marrow. Blood cell levels and symptoms can cause anaemia, which may Low levels of make you feel tired, breathless, red blood cells dizzy, and you may look pale may make you more likely to get Low levels of infections and may make it more white blood cells difficult to get rid of infections can cause you to bruise easily, Low platelet levels get frequent nosebleeds or have prolonged bleeding from cuts 12 Cancer Council
Bone marrow biopsy This type of biopsy can show if there are any lymphoma cells in the bone marrow. Your doctor will give you a local anaesthetic then insert a needle into your pelvic bone to remove a small piece of bone marrow. The needle is only inserted for a few seconds, but this may be painful. Ask your doctor for pain-relief or sedation before the procedure if it isn’t offered. The procedure takes about 30 minutes. CT scan The CT (computerised tomography) scan is a procedure that uses x-ray beams to take pictures of the inside of your body. Unlike a standard x-ray, which takes a single picture, a CT scan uses a computer to compile pictures of different areas throughout your body. This dye will make the scan pictures clearer, but it may make you feel flushed or hot for a few minutes. Rarely, more serious reactions occur, such as breathing difficulties or low blood pressure. Your doctor will take the necessary measures to manage any side effects. You need to lie still on a table while the large, round CT scanner slowly rotates around you. You may be asked to hold your breath for a few seconds or change position during the scan to help get better pictures. This painless scan takes about 10–15 minutes, and most people can go home as soon as it is finished. The dye that is injected into your veins before a CT scan is called a contrast solution and may contain iodine. If you are allergic to iodine, fish or dyes, let the person performing the scan know in advance. Diagnosis 13
MRI scan MRI (magnetic resonance imaging) is a less common scan used to detect lymphoma. The MRI scan uses magnetism and radio waves to create detailed cross-section pictures of the body. This scan generally takes 30–60 minutes. If you have a pacemaker or another type of metal object in your body, you cannot have an MRI scan. You will lie in a narrow metal cylinder that is open at both ends. If confined spaces make you feel claustrophobic or anxious, speak to your health care team before the scan. They may give you a mild sedative or arrange for you to speak through an intercom to the person operating the machine during the procedure. The machine is noisy during the scan. PET scan A positron emission tomography (PET) scan is a specialised imaging test that is only available at some hospitals. PET scans are only useful for some forms of lymphoma. Before the scan, you will be injected with a radioactive glucose (sugar) solution. You will be sedated or asked to sit quietly for 30–90 minutes while the glucose moves through your body. Your body will then be scanned for high levels of radioactive glucose. Active cells, such as cancer cells, have an increased uptake of this solution and are highlighted in the scan. It will take several hours to prepare for the scan and have it. You may want to take a book to read or bring a friend for company and support. 14 Cancer Council
Heart scans You might have one of the following scans to show how well your heart pumps blood. This may be done before, during or after chemotherapy treatment (see page 23). • Echocardiogram – This is known as a cardiac ECHO or cardiac ultrasound. A few small, sticky patches called electrodes are placed on your chest, and gel is spread over the area. The person performing the scan will use a small, paddle-shaped device to create pictures of your heart. You may be asked to hold your breath at times. This painless test can take up to an hour. • Gated heart pool scan – A small amount of blood is taken, mixed with radioactive material and re-injected into you. As the radioactive material is pumped through your heart, it can be seen on a computer screen. The scan takes about 45 minutes. The radiation will leave your body within a few hours. Talk to your doctor if you are concerned. Tell your doctor if you are pregnant or breastfeeding. You may not be able to have a gated heart pool scan. Gallium scan A gallium scan is an uncommon type of diagnostic test. A weak radioactive substance (gallium) is injected into a vein in your arm. Over 2–3 days, the gallium accumulates in areas of enlarged, abnormal lymph nodes, showing where lymphoma has spread. Diagnosis 15
Lumbar puncture (spinal tap) A lumbar puncture allows the doctor to examine the spinal fluid to determine if the cancer has affected your central nervous system. You will be given a local anaesthetic and a thin needle will be inserted into your lower back to remove some fluid. This may be done under x-ray guidance for people with spinal disease or arthritis. The lumbar puncture may be uncomfortable or painful. Tell your doctor how you are feeling. Common side effects include headaches and nausea, but these usually ease within a few hours. Some people also have a chest x-ray to check for enlarged lymph nodes in the chest. This is a painless scan. Prognosis Prognosis means the expected outcome of a disease. You may wish to discuss your prognosis and treatment options with your doctor, but it is not possible for any doctor to predict the exact course of your disease. Instead, your doctor can advise you on common issues that people with the same type of lymphoma experience. While some people may be cured of non-Hodgkin lymphoma after initial treatment, other people experience multiple episodes (often called relapses) of the disease, going in and out of remission (absence of disease symptoms) over several years. 16 Cancer Council
Stages of non-Hodgkin lymphoma Staging describes how far the lymphoma has spread. Each stage is also assigned a letter – for example, ‘A’ means you have no symptoms; ‘B’ means you have symptoms (e.g. fevers, night sweats). Diaphragm Affected lymph Diaphragm nodes Stage 1 – One lymph node area Stage 2 – Two or more lymph node is affected.

Diagnosis 17
Which health professionals will I see? Your GP may arrange the first tests to assess your symptoms. If these tests do not rule out cancer, you will usually be referred to a haematologist who will arrange further tests and advise you about treatment options. I trust my haematologist, she is very honest with me and it makes me feel secure in my choices. Andrea Specialist health professionals specialises in diagnosing and treating haematologist diseases of the blood, the lymphatic system and bone marrow prescribes and coordinates the course radiation oncologist of radiotherapy prescribes and coordinates the course medical oncologist of chemotherapy help administer drugs, including chemotherapy, nurses and provide care, information and support throughout your treatment 18 Cancer Council
A haematologist typically diagnoses and treats the lymphoma, often with chemotherapy and biological therapy. However, sometimes a medical oncologist may oversee your treatment for lymphoma. You will probably be cared for by a range of health professionals who specialise in different aspects of your treatment.

Treatment Treatment options for people with non-Hodgkin lymphoma vary. When planning your treatment, your doctor will look at a number of factors. This includes: • the type of lymphoma you have (e.g. low-grade lymphoma or aggressive lymphoma) • which parts of your body are affected • your age and general health. The aim of treatment is to control the lymphoma so that you go into remission. This is when the symptoms and signs of cancer reduce or disappear, and tests become normal or near normal. Remission may last for a long period of time, until the lymphoma becomes active again and treatment is required. This pattern of remission and relapse may repeat several times. Low-grade (indolent) lymphoma Some lymphoma, called low-grade or indolent lymphoma, grows very slowly and causes few problems. This is because there is little change in the disease over time. Your doctor may decide that you don’t need treatment initially, but will monitor your health with regular check-ups and blood tests. This is called watchful waiting or watch and wait. If there is a change or growth in the lymphoma that causes symptoms, and other warning signs appear, your doctor will recommend treatment. The treatment is usually chemotherapy but can include radiotherapy and biological therapies. Treatment 21
Understanding watchful waiting You may not have treatment Treating the lymphoma earlier straightaway, but instead have than necessary can cause regular check-ups to monitor unpleasant side effects. It can the cancer, known as watchful also make your body resistant waiting. Some people find this to treatment, so if you need it approach difficult to accept. later, it may not work as well. You might prefer to have treatment right away.

Your doctor may lymphoma. Results from clinical be able to put you in touch with studies have proven that there another patient who has had is no advantage to giving a similar experience and can treatment at an early stage. explain how they’ve coped. High-grade (aggressive) lymphoma High-grade or aggressive lymphoma grows much faster than low-grade lymphoma and needs treatment as soon as possible. The aim is to stop the active disease and cause remission. Chemotherapy is the main treatment for high-grade lymphoma. You may be given chemotherapy initially, then also have one or more other types of treatment. This may include radiotherapy, a stem cell transplant or biological therapies. 22 Cancer Council
Chemotherapy Chemotherapy is the use of drugs to kill or slow the growth of cancer cells. Treatment is usually given as a combination of drugs. Chemotherapy is often combined with other treatments, such as monoclonal antibodies or steroid therapy (see pages 26–29), or given as a palliative treatment (see page 35). Chemotherapy can be given in tablet form or injected into your veins (intravenously). Intravenous treatment can be given through a drip or a device called a tube or a line. Types of intravenous lines A thin tube that can stay in place for a PICC (Peripherally long period of time, inserted into one of inserted central catheter) the main veins in your arm. A thin tube with a dome-shaped opening (port) that is surgically inserted into a vein in your chest or arm. Needles are Port-a-cath (port) used to access the port-a-cath when it is required for treatment. It must be flushed regularly when not in use. A thin tube with several openings Central line (Central (lumens) that is inserted into a vein in venous catheter or CVC) your neck or chest. A small hollow plastic tube put into your Cannula hand or arm. Treatment 23
Occasionally, a small amount of chemotherapy is given via a lumbar puncture (see page 16). This is called intrathecal chemotherapy, and it is done to prevent or treat lymphoma in the brain or spinal cord. Many people have chemotherapy as an outpatient, although at times you may need a short stay in hospital. You will be closely monitored by your doctor after each course of treatment, and have further tests to see how the drugs have affected the lymphoma. Chemotherapy treatment may be repeated several times until the lymphoma goes into remission. Side effects Chemotherapy drugs can harm healthy, fast-growing cells, such as the cells in your hair, mouth and blood. This can cause side effects such as hair loss, mouth sores, nausea and tiredness. Side effects can make it hard for you to function as usual. Although many people continue to work and carry out their daily activities while having chemotherapy, you may need extra rest when you feel tired. Discuss any side effects you experience with your doctor or nurses. Most side effects are temporary, and your medical team can give you medication to help relieve symptoms. Tell your doctor about any medicines, herbal remedies, antioxidants or nutritional supplements you’re taking, as these may affect how chemotherapy works in your body. 24 Cancer Council

Treatment 25
Biological therapies Biological therapies (also called biotherapies) include a range of treatments derived from natural substances in the body, usually proteins. They are converted for use as medications. The therapies work in different ways to help the body fight cancer: Monoclonal antibodies – These are man-made versions of immune system proteins called antibodies. They work by targeting diseased cells, attaching to them and then helping the body’s immune system destroy them. This medication is given intravenously, and is used alone or with other treatments. Monoclonal antibodies available in Australia for lymphoma include rituximab (Mabthera®) and alemtuzumab (Campath®). One of these drugs may be used as a first treatment or combined with chemotherapy (see page 23). Immunotherapy – Strengthens the immune system so that it is able to find and attack cancer cells more effectively. One treatment is interferon, a hormone-like protein made by white blood cells that is injected under the skin. Vaccines can also be given to make your body produce antibodies to fight the lymphoma. Some types of immunotherapy are used to make the main treatment more effective. This is called adjuvant therapy. Granulocyte-colony stimulating factor (G-CSF) – Helps white blood cells recover faster following chemotherapy. This is given as an injection under the skin (subcutaneously). 26 Cancer Council
G-CSF is also sometimes used in stem cell transplants to help blood stem cells multiply quickly (see page 30). It can also be given after chemotherapy has finished. Side effects Side effects are specific to the medication used. They are very uncommon with some types of medication (e.g. G-CSF) but more common with others (e.g. interferon). Talk to your doctor about what may occur. Arrange to go to the hospital with a relative or friend if you can. You may feel unwell and weak following treatment, so it is helpful if someone can take you home. Radiotherapy Radiotherapy uses x-rays to kill cancer cells or harm them so they cannot multiply. It is generally used for stage 1 or stage 2 lymphoma when there are lymphoma cells in one or two areas of lymph nodes in a part of the body. If the lymphoma is more advanced or high-grade, you may have radiotherapy combined with chemotherapy (chemoradiotherapy). A course of radiotherapy is usually given daily over several weeks. Each session lasts for a few minutes, but it can take longer to wait for your appointment and set up the equipment. The overall course of treatment will depend on the type of non-Hodgkin lymphoma you have and your general health. Treatment 27
Radiotherapy is painless and you should not feel any discomfort during each session. While you are being treated, you will lie alone in a room under a large machine that delivers x-ray beams to the treatment area. You will be able to talk to the radiation therapist through an intercom. Radioimmunotherapy This is a type of high-power This treatment may cause targeted radiotherapy that side effects such as nausea or uses monoclonal antibodies tiredness. It is not commonly (see page 26) to deliver used in Australia and is only radiation to cancer cells. It available at a limited number is also known as radioactive of treatment centres. antibody treatment. Side effects Radiotherapy often causes side effects, such as tiredness and local skin irritation. Most side effects are temporary and your doctor can prescribe medication to reduce any discomfort. Other side effects depend on the part of your body being treated. For example, radiotherapy to the abdomen may cause an upset stomach, nausea, diarrhoea and infertility. Radiotherapy to the neck can affect your sense of taste and make your mouth sore and dry. For more details on what side effects you may experience, talk with your doctor or call Cancer Council Helpline 13 11 20 for a free copy of Understanding Radiotherapy. 28 Cancer Council
Steroid therapy Steroids are made naturally in the body, but they can also be produced artificially and used as drugs. Corticosteroids are a type of steroid often given with chemotherapy to make the treatment more effective. Side effects People having steroid therapy may have various side effects, depending on the dose and how long they have treatment. Most side effects are temporary and will gradually disappear after you stop taking the medication. If you have steroids for a short amount of time, your symptoms may include: • an increased appetite • feelings of restlessness • insomnia • weight gain. If taken for several months, steroids can also cause fluid retention, high blood pressure, high blood glucose levels and diabetes. You will be more likely to get infections and, over time, your skin, muscles and bones may weaken. Your medical team will monitor you during steroid treatment. Tell your doctor or nurse if you have any uncomfortable or unpleasant side effects. There are ways to reduce the side effects you experience. Treatment 29
Peripheral blood stem cell transplant A peripheral blood stem cell transplant may be an option if the lymphoma returns (relapses) or does not respond to standard therapy. Stem cells are immature cells from which blood cells develop. Most stem cells are found in the bone marrow, but a small number are also found in your blood. These are called peripheral blood stem cells. The general transplant process is described here, but procedures vary from person to person based on their circumstances. Talk to your health care team about what to expect, including how long you will be in hospital. There are two types of transplants you may have: • autologous transplant – your own stem cells are extracted from your body, frozen and injected back into your body after further chemotherapy • allogeneic transplant – stem cells are collected from another person – a matched donor, usually a family member or a volunteer donor – and injected into your body after chemotherapy. For detailed information about transplants, contact the Leukaemia Foundation on 1800 620 420 or www.leukaemia.org.au. For more information about stem cell harvesting, visit the Lymphoma Australia website at www.lymphoma.org.au. 30 Cancer Council
It is important to have a dental check-up and have any problems fixed before a transplant, as the mouth is a major source of bacteria. If left untreated, mouth problems can cause infections after the transplant. If your own stem cells are used (autologous transplant), you will usually be given granulocyte-colony stimulating factor (G-CSF) before the transplant to help the stem cells multiply as quickly as possible. These stem cells are released from the bone marrow into the blood. Once there are enough stem cells in your bloodstream they will be collected in a cell separating machine. This process is called apheresis. The patient usually has two needles inserted, one in each arm. One needle is used to draw the cells away into the machine and the other needle is used to return the blood cells to the body. The machine separates the blood into different components. The stem-cell rich white blood cell layer is collected while the other blood cells are returned to the patient. Apheresis is a continuous process and can take several hours. Once there are enough stem cells collected, they are frozen and stored until needed. This process is referred to as a stem cell harvest. Sometime after your stem cells have been collected, you will be given high-dose chemotherapy to kill any remaining lymphoma cells. The drugs will also destroy your own blood-forming cells in the bone marrow, which can cause side effects (see page 24). Treatment 31
A day or so after the high-dose chemotherapy, your stem cells will be thawed and returned to you intravenously (see page 23). These healthy stem cells help to restore your bone marrow. You may have blood and platelet transfusions in the lead up to and during your transplant. Side effects High-dose chemotherapy, and the transplant itself, can cause serious, life-threatening side effects. Your doctor will talk to you about this before the transplant. You may also have some temporary side effects, including: • fatigue • nausea, vomiting and diarrhoea • mouth ulcers • hair loss • low blood counts (e.g. increased risk of infections). After the transplant, you will probably continue to have side effects caused by chemotherapy, including fatigue. Your blood counts may remain low for a while. Over time, these symptoms will go away. For more information about coping with side effects, call Cancer Council Helpline 13 11 20. Some people have their stem cells collected directly from the bone marrow by suction (aspiration) under general anaesthetic. This is called a bone marrow harvest. This is not as common as peripheral blood stem cell harvesting. 32 Cancer Council

Recovery after a transplant When your blood counts have risen and your general health improves, you can go home, but you will need regular follow-up care, such as blood tests, to check your progress. You may still need to have blood or platelet transfusions. These tests are usually done as an outpatient. While your immunity is low, you may have to regularly take medications to reduce the risk of infection. It is not uncommon to become unwell after treatment and have to go back into hospital. Before leaving the hospital, ask your doctor if there is a contact number you can have in case you become unwell. The time it takes to recover varies depending on your situation. Your health care team, including your doctor, nurses and pharmacist, will all be able to discuss with you what you might expect while you recuperate. You can also call the Helpline for support and advice. 34 Cancer Council
Palliative treatment Palliative treatment helps to improve a person’s quality of life by alleviating symptoms of cancer without trying to cure the disease. It is particularly important for people with advanced cancer. However, it is not just for end-of-life care and it can be used at different stages of cancer. Often treatment is focused on pain relief, but it can involve the management of other physical and emotional symptoms. Treatment may include radiotherapy, chemotherapy, blood transfusions and medication. Call Cancer Council Helpline 13 11 20 for more information on palliative treatment and advanced cancer. Mum has called her treatments palliative from day one because they give her relief from the pain and stress of having a serious illness. Her palliative care team provide that extra layer of support.

Making treatment decisions Sometimes it is difficult to decide on the right treatment. You may feel that everything is happening so fast you don’t have time to think things through. If you are feeling unsure about your options, check with your doctor how soon your treatment should start, and take as much time as you can before making a decision. Understanding details about the disease, the available treatments and their possible side effects will help you make a well-informed decision. This decision will also take into account your personal values and the things that are important to you and your family. It is common to feel overwhelmed by information so it may help if you read and talk about the cancer gradually. • Weigh up the advantages and disadvantages of different treatments, including the impact of any side effects. • If only one type of treatment is recommended, ask your doctor why other choices have not been offered. • If you have a partner, you may want to discuss the treatment options together. You can also talk to friends and family. You have the right to accept or refuse any treatment offered by your doctors and other health care professionals. Some people with advanced cancer choose treatment even if it only offers a small benefit for a short period of time. Others want to make sure the benefits outweigh the side effects so that they have the best possible quality of life. Some people choose options that focus on reducing symptoms and make them feel as well as possible. Making treatment decisions 37
Talking with doctors When your doctor first tells you that you have lymphoma you may not remember all the details about what you are told. You may want to see the doctor again before deciding on treatment. Ask for the time and support to make your decision. If you have questions, it may help to write them down before you see the doctor. You can also check the list of suggested questions on page 53. Taking notes or recording the discussion can help too. Many people like to have a family member or friend go with them to take part in the discussion, take notes or simply listen. If your doctor uses medical terms you don’t understand, ask for an explanation in everyday language. You can also check a word’s meaning in the glossary (see page 54). If you have several questions for your doctor, ask if it is possible to book a longer appointment. A second opinion Getting a second opinion from another specialist may be a valuable part of your decision-making process. It can confirm or clarify your doctor’s recommendations and reassure you that you have explored all of your options. Some people feel uncomfortable asking their doctor for a second opinion, but specialists are used to people doing this. 38 Cancer Council
Your doctor can refer you to another specialist and send your initial results to that person. You can get a second opinion even if you have started treatment or still want to be treated by your first doctor. Alternatively, you may decide you would prefer to be treated by the doctor who provided the second opinion. Taking part in a clinical trial Your doctor may suggest you consider taking part in a clinical trial. Doctors run clinical trials to test new or modified treatments and ways of diagnosing disease to see if they are better than current methods. Over the years, trials have improved treatments and led to better outcomes for people diagnosed with cancer. If you join what is called a randomised trial for a new treatment, you will be chosen at random to receive either the best existing treatment or the promising new treatment. To help you decide whether or not to participate, you can talk to your specialist or the clinical trials nurse. If you’re still unsure, you can also ask for a second opinion from an independent specialist. If you do decide to take part, you have the right to withdraw from the trial at any time; doing so will not jeopardise your ongoing treatment for cancer. For more information about clinical trials and other research, including questions to ask your doctor and how to find a suitable study, call Cancer Council Helpline 13 11 20. You can also find trials on the website, www.australiancancertrials.gov.au. Making treatment decisions 39
Looking after yourself Cancer can cause physical and emotional strain. It can also impact on your body image, relationships and outlook for the future. It’s important to take time to look after yourself by eating well, exercising, reducing stress and improving your wellbeing. Healthy eating Eating nutritious food will help you keep as well as possible and cope with cancer and treatment side effects. Depending on your treatment, you may have special dietary needs. A hospital dietitian can help you manage any eating difficulties and choose the best foods and meals for your situation. Cancer Council Helpline can send you free information about nutrition and cancer. Being active Research shows it is helpful to stay active and exercise regularly if you can. Physical activity, even if gentle or for a short duration, helps to improve circulation, reduce tiredness and elevate mood. The amount and type of exercise you do will depend on what you are used to, how well you feel and what your doctor advises. If you aren’t used to exercise or haven’t exercised for a while, make small changes to your daily activities. You could walk to the shops, take the stairs, do some gardening or join a gentle exercise class. If you want to do more vigorous or weight-bearing exercise, ask your medical team what is best for you. Cancer Council Helpline can send you free information about exercise and cancer. 40 Cancer Council
Complementary therapies Complementary therapies are treatments that may help you cope better with side effects such as pain. They may also increase your sense of control over what is happening to you, decrease your stress and anxiety, and improve your mood. There are many types of complementary therapies, such as herbal medicine, acupuncture, massage, relaxation and meditation. Some treatment centres offer these therapies as part of their services, but you may have to go to a private practitioner. Self-help CDs or DVDs can also guide you through different techniques. Let your doctor know about any complementary therapies you are using or thinking about trying. Some therapies may not be appropriate, depending on your medical treatment. For example, herbs and nutritional supplements may interact with your medication or surgery, resulting in harmful side effects. Massage, acupuncture and exercise therapies should also be modified if you have lowered immunity, low platelets or fragile bones. Call the Helpline on 13 11 20 for more information and resources about complementary therapies. Alternative therapies are commonly defined as those used instead of conventional treatments. These therapies may be harmful if people with cancer delay or stop using conventional treatment in favour of them. Examples are coffee enemas and magnet therapy. Looking after yourself 41
Relationships with others For many people, the experience of having cancer and any ongoing challenges causes them to make some changes in their life. You may also have a new outlook on your values, priorities, or life in general. Some people find that these changes can affect their relationships. However, sharing your thoughts and feelings with family, friends and colleagues may help to strengthen your relationships with them. If you feel uncomfortable talking about your feelings, take your time and approach others when you are ready. People usually appreciate insight into how you are feeling and guidance on providing support during and after treatment. Calling Cancer Council Helpline may help you build your confidence to discuss your feelings with others. Give yourself time to adjust to your cancer diagnosis, and do the same for friends and family. People often react in different ways, for example being overly positive, playing down fears, or keeping a distance. They are also dealing with the diagnosis and the changes. If someone’s behaviour upsets you, it might help to discuss how you both feel about the situation. The whole time I was on chemotherapy and radiotherapy, my friend called me every day between 8am and 9am. She could hear if I was well by my voice. There aren’t many friends like that around.

Sexuality, intimacy and cancer Having cancer can affect your sexuality in physical and emotional ways. The impact of these changes depends on many factors, such as treatment and side effects, the way you and your partner communicate, and your self-confidence. Knowing the potential challenges and addressing them will help you adjust to these changes. Some people with cancer have the support of a partner, while others do not. If you meet a new partner during or after treatment, it can be difficult to talk about your experiences, particularly if the cancer has had an impact on your sexuality. Sexual intercourse may not always be possible during and immediately after treatment, but closeness and sharing are vital to a healthy relationship. Call Cancer Council Helpline 13 11 20 for more information on sexuality and cancer. Some treatments may affect your fertility permanently or temporarily. If having children is important to you, talk to your doctor before you start treatment. Contraception Depending on the type of cancer and treatment you have, your doctors may advise you to use certain types of contraception, such as condoms, during and after treatment. This is to protect your partner and also to avoid pregnancy, as some treatments, such as chemotherapy, can be harmful to your partner and can harm a developing baby. Ask your doctors what precautions to take. Looking after yourself 43
