What is lymphoma? —
This is a cancer of lymphocytes, which are infection-fighting cells of the body's lymphatic system. The lymphatic system is made up of organs all over the body that make and store cells that fight infection (figure 1).
When people have lymphoma, their lymphocytes become abnormal and grow out of control. These cells can travel to different parts of the body. Often, the abnormal cells collect in small, bean-shaped organs called lymph nodes. This causes the lymph nodes to swell.
There are different types of lymphoma. Some grow very slowly, and others grow much faster. Sometimes, people start with a slow-growing type of lymphoma that later becomes fast-growing.
What are the symptoms of lymphoma? —
The first sign is often 1 or more large, swollen lymph nodes. They can be felt under the skin, but are usually not painful. They are often in the neck, groin, armpit, or stomach.
Lymph nodes deeper in the body can also become swollen and cause symptoms. For example, swollen lymph nodes around the lungs can cause a cough or trouble breathing.
Other symptoms of lymphoma include:
●Fever
●Weight loss
●Night sweats that soak your clothes
All of these symptoms can also be caused by conditions that are not lymphoma. But if you have these symptoms, tell your doctor or nurse.
Is there a test for lymphoma? —
Yes. Your doctor or nurse will do an exam and ask about your symptoms. They might order other tests, including:
●Lymph node biopsy – A doctor removes 1 of the swollen lymph nodes. It is looked at under a microscope to see if lymphoma cells are present.
●Bone marrow biopsy – A doctor uses a needle to remove a small sample of bone marrow, which is the spongy tissue in the center of some bones. The sample is then examined under a microscope to see if it has lymphoma.
●Other biopsy – In some cases, a small sample of other abnormal tissues are removed to check for lymphoma.
●CT scan, PET scan, or other imaging tests – These create pictures of the inside of the body and can show abnormal growths.
What is lymphoma staging? —
This is a way in which doctors find out how far lymphoma has spread within the lymphatic system or within the body.
The right treatment for you depends, in part, on the stage of your lymphoma. Your treatment also depends on the type of lymphoma you have, your age, and your other health problems.
How is lymphoma treated? —
Doctors can treat it in different ways. People with some forms get treated right away. But people with lymphoma that is growing slowly and not causing symptoms often do not need treatment at first.
People with lymphoma often have 1 or more of the following treatments:
●Chemotherapy – These are medicines that kill cancer cells or stop them from growing.
●Immunotherapy – These are medicines that kill cancer cells by attacking the lymphoma cells.
●Radiation therapy – This kills cancer cells.
●Bone marrow transplant (also called "stem cell transplant") – This replaces cells in the bone marrow that are killed by chemotherapy or radiation.
What happens after treatment? —
You will be checked every so often to see if the lymphoma comes back. Regular follow-up will include talking with your doctor and having exams. Sometimes, your doctor will also do blood tests or imaging tests.
Watch for the symptoms listed above. Having those symptoms could mean that the cancer has come back. Tell your doctor or nurse if you have any symptoms.
What happens if the lymphoma comes back? —
You might have more chemotherapy, immunotherapy, radiation, or a bone marrow transplant.
What else should I do? —
Follow all of your doctors' instructions about visits and tests. It's also important to talk to your doctor about any side effects or problems you have during treatment.
Getting treated for lymphoma involves making many choices, such as what treatment to have and when.
Always let your doctors and nurses know how you feel about a treatment. Any time you are offered a treatment, ask:
●What are the benefits of this treatment? Is it likely to help me live longer? Will it reduce or prevent symptoms?
●What are the risks to this treatment?
●Are there other options besides this treatment?
●What happens if I do not have this treatment?
