Topic Overview
Is this topic for you?
Lymphomas are either Hodgkin's lymphomas or non-Hodgkin's lymphomas. Hodgkin's lymphomas have a type of cell called Reed-Sternberg cells. Lymphomas without these cells are non-Hodgkin's lymphomas. This topic is about non-Hodgkin's lymphoma (NHL). To learn about Hodgkin's lymphoma, see the topic Hodgkin's Lymphoma.
What is non-Hodgkin's lymphoma?
Lymphoma is cancer that begins
in the lymph system in white blood cells called lymphocytes. When these cells become abnormal, they
don't protect the body from infection or disease. They also grow without control and may form lumps
of tissue called tumors.
NHL can start almost
anywhere in the body. It may start in a single
lymph node, a group of lymph nodes, or an organ such
as the
spleen. Or it can spread to almost any part of the body,
including the liver and
bone marrow.
There are many types of NHL. Sometimes they are grouped as:
- Slow-growing lymphomas, which spread slowly and cause few symptoms. These may also be called indolent or low-grade lymphomas.
- Fast-growing lymphomas, which spread quickly and cause severe symptoms. These may also be called aggressive lymphomas and may be classified as intermediate-grade or high-grade.
Treatment can cure some
people and may allow others to live for years. How long you live depends on the
type of NHL you have and the stage of your disease (how far it has progressed).
What causes non-Hodgkin's lymphoma?
The cause of
NHL is not known. The abnormal cell changes may be triggered by an infection or
exposure to something in the environment. Or it may be linked to gene changes (mutations). NHL is not contagious.
What are the symptoms?
Symptoms of NHL
include:
- A painless swelling of the lymph nodes in the neck, underarm,
or groin. This is the most common symptom.
- Fever not caused by
another health problem.
- Night sweats.
- Extreme
fatigue.
- Weight loss you can't explain.
- Pain in the belly or back.
How is non-Hodgkin's lymphoma diagnosed?
Your
doctor will do a physical exam and ask you questions about your health. The
exam includes checking the size of your lymph nodes in your neck, underarm, and
groin.
Your doctor will take a piece of body tissue (biopsy) to diagnose NHL. The tissue usually is taken
from a lymph node. You may have other tests to find out what kind of NHL you have.
How is it treated?
Your treatment depends on the
type of lymphoma you have, the stage of the disease, your age, and your general
health. You may not need treatment until you have symptoms. NHL is usually treated with chemotherapy. Sometimes radiation or radiation with chemotherapy may be used. Or you may have targeted therapy with monoclonal antibodies.
If treatment doesn't work, or if NHL comes back after initial treatment, you may have chemotherapy along with a stem cell transplant.

Cause
Experts don't know what causes non-Hodgkin's lymphoma (NHL).
When a person has
non-Hodgkin's lymphoma, abnormal rapid cell growth occurs. This abnormal growth
may need a "trigger" to start, such as an infection or exposure to something in
your environment. There is also a link between NHL and problems with the immune system.
NHL is not contagious and is not caused by injury.
Symptoms
Symptoms of
non-Hodgkin's lymphoma (NHL) include:
- A painless swelling of the lymph nodes in the neck, underarm, or groin. This is the most common symptom.
- Unexplained fever.
- Night sweats.
- Feeling very tired.
- Unexplained weight loss.
- Itchy
skin.
- Reddened patches on the skin.
- A cough or shortness of
breath.
- Pain in the belly or
back.
What Happens
In
non-Hodgkin's lymphoma (NHL), white blood cells called lymphocytes divide and grow without order or
control. The abnormal lymphocytes usually are either B-cell or T-cell lymphocytes. But most cases of NHL involve B-cell lymphocytes.
Lymph tissue is present in many
areas of the body, so NHL can start almost anywhere in the
body. It may occur in a single
lymph node, a group of lymph nodes, or an organ. And
it can spread to almost any part of the body, including the
liver,
bone marrow, and
spleen.
NHL may be classified as:
- Slow-growing lymphomas, which spread slowly and cause few symptoms. These may also be called indolent or low-grade lymphomas.
- Fast-growing lymphomas, which spread quickly and cause severe symptoms. These may also be called aggressive lymphomas and may be classified as intermediate-grade or high-grade.
Over time, lymphoma cells may replace the normal cells in
the bone marrow. Bone marrow failure results in the inability to produce red
blood cells that carry oxygen, white blood cells that fight infection, and
platelets that stop bleeding.
Long-term survival depends on the
type of non-Hodgkin's lymphoma and the stage of the disease when it is
diagnosed. About 80 out of 100 people diagnosed with non-Hodgkin's
lymphoma are alive 1 year after the disease is diagnosed. That number drops to
about 67 out of 100 at 5 years, and 57 out of 100 at 10 years.footnote 1
What Increases Your Risk
Some things can increase your chances of getting non-Hodgkin's lymphoma (NHL). These things are called risk factors. But many people who get non-Hodgkin's lymphoma don't have any of these risk factors. And some people who have risk factors don't get the disease.
Risk factors include:footnote 2
- Being male. NHL is more common in men than
in women.
- Age. The likelihood of getting NHL
increases as you get older.
- Impaired immune system. NHL is most common among those who have an
impaired immune system, an autoimmune disease, or HIV
or AIDS. It also occurs among those who take immunosuppressant medicines, such
as medicines following an organ transplant.
- Viral infection. A
viral infection, such as
Epstein-Barr virus, increases the risk of developing
NHL.
- Bacterial infection. Infection with
Helicobacter pylori increases the risk of lymphoma
involving the stomach.
- Environmental exposure. Exposure to agricultural pesticides or fertilizers, solvents, and other chemicals may increase the
risk of developing NHL.
When To Call a Doctor
Call your doctor to schedule an
appointment if you have had any symptoms for longer than 2 weeks, such
as:
- Painless swelling in the lymph nodes in the
neck, underarm, or groin.
- Unexplained fever.
- Drenching
night sweats.
- Extreme fatigue.
- Unexplained weight loss
in the past 6 months.
- Itchy skin.
- Cough or shortness
of breath.
- Pain in the belly or back.
Who to see
Health professionals who can evaluate your symptoms of
non-Hodgkin's lymphoma (NHL) include:
When NHL is suspected, a tissue sample (biopsy) is needed to make a diagnosis. A biopsy for
non-Hodgkin's lymphoma is usually taken from a lymph node. But other tissues
may be sampled as well. A
surgeon will remove a sample of tissue so that a
pathologist can examine it under a microscope to check
for cancer cells.
Non-Hodgkin's lymphoma is usually treated by a
medical oncologist or a
hematologist. If you need radiation therapy, you
will also see a
radiation oncologist.
To prepare for your appointment, see the topic Making the Most of Your Appointment.
Exams and Tests
If
non-Hodgkin's lymphoma (NHL) is suspected, your doctor
will ask about your medical history and perform a physical exam. This
exam includes checking for enlarged
lymph nodes in your neck, underarm, and groin.
Diagnostic tests
A tissue sample (biopsy) is needed to make a diagnosis.
A biopsy for non-Hodgkin's lymphoma is usually taken from a
lymph node, but other tissues may be sampled as
well.
A
bone marrow aspiration and biopsy is usually done to find
out if lymphoma cells are present in the bone marrow.
Other tests
Your doctor
may also order other tests, including:
- Blood tests, such as a
chemistry screen to measure the levels of several
substances in the blood and a
CBC (complete blood count) to provide information
about the kinds and numbers of cells in the blood.
- A
chest X-ray, to provide a picture of the inside of the chest.
- A
CT scan or
MRI, to provide detailed
pictures of the inside of the chest, abdomen, and pelvis.
- A PET scan, to show areas
of increased
metabolic activity. Metabolic activity is often high in cancer cells.
- Lab tests, such as flow cytometry, that check the types of cells in a biopsy sample. These tests help
your doctor find out the type of lymphoma.
- Lumbar puncture (also called a spinal tap), to find out whether lymphoma cells
are in the fluid (cerebrospinal fluid, or CSF)
surrounding your brain and spinal cord.
Treatment Overview
Treatment for non-Hodgkin's lymphoma (NHL) depends
on:
- The
stage of the disease.
- The type of lymphoma. The kind of treatment
you have will depend on whether you have B-cell or T-cell lymphoma and whether
it is fast-growing or slow-growing.
- The size of the tumor, where the lymphoma is located, and what organs are
involved.
- Your general health.
Your doctor will work with you and your medical team (which may include an oncologist, a hematologist, and an oncology nurse) to come up with your treatment plan.
Treatment options
- Watchful waiting (surveillance) is a
period of time after the diagnosis of some types of NHL when you are not receiving treatment but are still being watched closely by your doctor.
- Radiation therapy is often the treatment of choice for localized slow-growing (indolent or low-grade) NHL. For more information, see Other Treatment.
- Chemotherapy kills cancer cells or stops them from dividing. The way chemotherapy is taken depends on the type and stage of cancer.
- Targeted therapy with monoclonal antibodies destroys cancer cells without harming normal cells.
- A stem cell transplant may be used to treat NHL that has come back. Or it may be used right after you have very high-dose chemotherapy.
Side effects
A common concern of cancer patients are the side effects of treatments like chemotherapy and radiation. Your medical team will let you know ahead of time what side effects you can expect and help you manage them. And there are things you can do at home. To learn more, see Home Treatment.
Recurrent NHL
Sometimes NHL comes back after treatment. This is called recurrence or relapse. Treatments for recurrent NHL include chemotherapy, radiation, or a combination of the two. This treatment may be followed by a stem cell transplant.
Follow-up care
You will need regular exams after you have been treated for NHL.
Let your doctor know if you have any problems as soon as
they appear.
Support
Finding out that you have cancer can change your life. You may feel like your world has turned upside down and you have lost all control. Talking with family, friends, or a counselor can really help. Ask your doctor about support groups. Or call the American Cancer Society (1-800-227-2345) or visit its website at www.cancer.org.
For support in managing the many changes that having cancer can bring, see the topic
Getting Support When You Have Cancer.
What to think about
Your doctor may use
the term "remission" instead of "cure" when talking about the effectiveness of
your treatment. Although many people with non-Hodgkin's lymphoma are
successfully treated, the term remission is used because cancer can return. It
is important to discuss with your doctor the possibility of recurrence.
Even after effective treatment for NHL, you may be at slightly higher
risk for other types of cancer, especially melanoma, lung, brain, kidney, and
bladder cancers. Be watchful for any symptoms of cancer.
Additional information about NHL is provided by the National Cancer Institute at www.cancer.gov/cancertopics/types/non-hodgkin.
Palliative care
Palliative care is a kind of care for people who have a serious illness. It's different from care to cure your illness. Its goal is to improve your quality of life-not just in your body but also in your mind and spirit.
You can have this care along with treatment to cure your illness.
Palliative care providers will work to help control pain or side effects. They may help you decide what treatment you want or don't want. And they can help your loved ones understand how to support you.
If you're interested in palliative care, talk to your doctor.
For more information, see
the topic
Palliative Care.
End-of-life care
For some people who have advanced cancer, a time comes when treatment to cure the cancer no longer seems like a good choice. This can be because the side effects, time, and costs of treatment are greater than the promise of cure or relief. But you can still get treatment to make you as comfortable as possible during the time you have left. You and your doctor can decide when you may be ready for hospice care.
For more information, see
the topics:
Prevention
There is no known way to prevent
non-Hodgkin's lymphoma (NHL).
Home Treatment
You can do things at home to help manage your side effects. If your doctor has given you instructions or medicines to treat these symptoms, be sure to follow them. In general, healthy habits such as eating a balanced diet and getting enough sleep and exercise may help control your symptoms.
- Home treatment for nausea or vomiting
includes watching for and treating early signs of dehydration, such as a dry
mouth or feeling lightheaded when you stand up. Eating smaller meals may help. A little bit of ginger candy or ginger tea can help too.
- Home treatment for diarrhea includes
resting your stomach and being alert for signs of dehydration. Check with your
doctor before you use any nonprescription medicines for your
diarrhea.
- Home treatment for constipation
includes gentle exercise along with adequate intake of fluids and a diet that
is high in fruits, vegetables, and fiber. Check with your doctor before you use a
laxative for your constipation.
Other problems that can be treated at home include:
- Sleep problems.
If you have trouble sleeping, tips such as going to bed at a regular time and getting exercise daily can help.
- Feeling very tired. If you lack energy or become weak easily, try to manage your energy and get extra rest.
- Sore mouth. Home treatment measures can ease mouth pain and speed healing.
- Hair loss. Tips include using a mild shampoo and a soft hairbrush.
- Pain. Home treatment can help you manage pain.
Handling the stress of having cancer
Having cancer can be very stressful, and it may feel overwhelming to face the challenges in front of you. Finding new ways of coping with the symptoms of stress may improve your overall quality of life.
These ideas may help:
- Get the support you need. Spend time with people who care about you, and let them help you.
- Take good care of yourself. Get plenty of rest, and eat nourishing foods.
- Talk about your feelings. Find a support group where you can share your experience.
- Try new ways to relax. And do things each day that help you stay calm and relaxed. Stress reduction techniques may help.
Medications
Your doctor may prescribe medicines that
will affect the growth of
non-Hodgkin's lymphoma and relieve your symptoms.
Chemotherapy
Chemotherapy may be used alone or with radiation therapy. Sometimes a
combination of chemotherapy medicines is more effective than a single
drug.
The most commonly used combination is called CHOP. It combines four medicines: cyclophosphamide, doxorubicin, vincristine, and prednisone.
Your doctor will work with you to find the best medicine for the type of lymphoma you have.
Chemotherapy causes many side effects. For help with how to deal with these, see Home Treatment. Your doctor may
prescribe
medicines to control nausea and vomiting from
chemotherapy.
Monoclonal antibodies
Targeted therapy uses monoclonal antibodies in medicine that is injected into the body so these antibodies can attach to cancer cells and destroy them. The monoclonal antibodies used to treat NHL include:
- Rituximab (Rituxan).
- Alemtuzumab (Campath).
- Ibritumomab (Zevalin).
- Tositumomab (Bexxar).
Other medicines
Some treatments use interferon or antibiotic medicines. Your doctor will suggest the treatment that works best for your kind of lymphoma.
What to think about
You may not be able to become
pregnant or father a child after chemotherapy treatment. Discuss fertility
issues with your doctor before starting treatment. Chemotherapy medicines can
also cause birth defects. If you are pregnant or wish to father a child,
discuss the risk of birth defects with your doctor before using any
chemotherapy medicine.
Surgery
Surgery is often used to obtain a biopsy sample when non-Hodgkin's lymphoma is being diagnosed or classified. But surgery is rarely used for treatment.
Other Treatment
Radiation therapy
Radiation therapy
for non-Hodgkin's lymphoma (NHL) may be given in different ways.
- With external radiation, X-rays from a machine are aimed at the part of the body with the lymphoma.
- With targeted radiation, monoclonal antibodies are injected into the blood and deliver radiation directly to the cancer cells. This is done by making a medicine in which a radioactive form of an element (such as iodine) is attached to a monoclonal antibody.
- With whole-body radiation, the entire body gets radiation. This may be done if you are getting a stem cell transplant.
Stem cell transplants
A stem cell transplant may be used to treat NHL that is in remission or that has come back. Stem cells may be obtained from blood, through a peripheral blood stem cell transplant (PBSCT). Or stem cells can be obtained from bone, in a bone marrow transplant (SBMT). PBSCT is the most common method for treating NHL.
A stem cell transplant may be done right after you have very high-dose chemotherapy. (You may also have radiation to your entire body.) The stem cell transplant is done to replace your damaged bone marrow cells with healthy stem cells. A stem cell transplant may be offered as part of standard treatment or in a clinical trial.
Clinical trials
Clinical trials are research studies that try to find better NHL treatments. Your doctor may suggest that you join a clinical trial. Some treatments being used in clinical trials include lymphoma vaccines and stem cell transplants with high-dose chemotherapy. If you are interested in taking part in a clinical trial, check with your doctor to see if any are available in your area.
Complementary therapy
People sometimes use complementary therapies
along with medical treatment to help relieve symptoms and side effects of
cancer treatments. Some of the complementary therapies that may be helpful
include:
These mind-body treatments may help you feel better. They can make it easier to cope with treatment. They also may reduce chronic low back pain, joint pain, headaches, and pain from treatments.
Before you try a complementary therapy, talk to your doctor about the possible value and potential side effects. Let your doctor know if you are already using any such therapies. They are not meant to take the place of standard medical treatment.
