Non-Hodgkin Lymphoma: Overview
What is non-Hodgkin lymphoma?
Cancer is made of changed cells that grow out of control. The changed (abnormal) cells
often grow to form a lump or mass called a tumor. Cancer cells can also grow into
(invade) nearby areas. And they can spread to other parts of the body. This is called
Non-Hodgkin lymphoma (NHL) is cancer that starts in the lymphatic system. The lymphatic
system is part of the immune system. It helps the body fight infection.
With non-Hodgkin lymphoma, cells in the lymphatic system grow out of control. This
causes swelling in the lymph nodes. These cancer cells can also spread to other areas
of the body, such as the spleen.
Non-Hodgkin lymphoma is different from Hodgkin lymphoma. There are many different
types of non-Hodgkin lymphoma. They grow at different rates and are treated in different
Who is at risk for non-Hodgkin lymphoma?
A risk factor is anything that may increase your chance of having a disease. The exact
cause of someone’s cancer may not be known. But risk factors can make it more likely
for a person to have cancer. Some risk factors may not be in your control. But others
may be things you can change.
Risk factors for non-Hodgkin lymphoma include:
Being a man
History of certain infections, such as the hepatitis C virus, H. pylori, or the Epstein-Barr
A weak immune system
Past cancer treatment, such as some kinds of chemotherapy or radiation therapy
Having certain autoimmune disorders, such as rheumatoid arthritis and celiac disease
Contact with certain chemicals, such as benzene and some pesticides
Breast implants (this is rare)
Talk with your healthcare provider about your risk factors for non-Hodgkin lymphoma
and what you can do about them.
Can non-Hodgkin lymphoma be prevented?
There’s no sure way to prevent non-Hodgkin lymphoma.
Are there screening tests for non-Hodgkin lymphoma?
There are currently no regular screening tests for non-Hodgkin lymphoma. Screening
tests are done to check for disease in people who don’t have symptoms.
What are the symptoms of non-Hodgkin lymphoma?
Non-Hodgkin lymphoma may not cause symptoms until the cancer has grown very large.
They may also seem like other health problems at first. This is because NHL can cause
many different types of symptoms. It depends on where the cancer starts in your body.
Here are some common symptoms of NHL:
Swollen lymph nodes that don’t hurt and don’t go away. These are often in the neck,
groin, or underarm, or above the collarbone.
Tiredness or weakness
Infections that keep coming back
Abnormal sweating, especially at night
Loss of weight without trying
Some symptoms depend on where the cancer is. For example, NHL in the belly (abdomen)
Swelling in the belly
Feeling full after eating only a small amount
Upset stomach (nausea), vomiting, or stomach pain
NHL in the chest can cause:
Many of these may be caused by other health problems. But it’s important to see your
healthcare provider if you have these symptoms. Only a healthcare provider can tell
if you have cancer.
How is non-Hodgkin lymphoma diagnosed?
The most common way to find non-Hodgkin lymphoma is when someone sees a doctor because
of symptoms. Your healthcare provider will ask you about your health history, symptoms,
risk factors, and family history of disease. He or she will also give you a physical
You may also have one or more of these tests:
A biopsy is the only way to confirm cancer. Small pieces of tissue are taken and checked
for cancer cells.
After a diagnosis of NHL, you’ll likely need other tests. These help your healthcare
providers learn more about your cancer. They can help determine the stage of the cancer.
The stage is how much, where, and how far the cancer has spread (metastasized) in
your body. It’s one of the most important things to know when deciding how to treat
Once your cancer is staged, your healthcare provider will talk with you about what
the stage means for your treatment. Be sure to ask your healthcare provider to explain
the stage of your cancer to you in a way you can understand.
How is non-Hodgkin lymphoma treated?
Your treatment choices depend on the type of non-Hodgkin lymphoma you have, test results,
and the stage of the cancer. The goal of treatment may be to cure you, control the
cancer, or to help ease problems caused by the cancer. Talk with your healthcare team
about your treatment choices, the goals of treatment, and what the risks and side
effects may be.
Types of treatment for cancer are either local or systemic. Local treatments remove,
destroy, or control cancer cells in one area. Radiation and surgery are local treatments.
Systemic treatment is used to destroy or control cancer cells that may have traveled
around your body. When taken by pill or injection, chemotherapy, immunotherapy, and
targeted therapy are systemic treatments.
You may have just one treatment or a combination of treatments. You will also have
tests during treatment to see how well the treatment is working.
Non-Hodgkin lymphoma may be treated with:
Stem cell transplant
Talk with your healthcare providers about your treatment options. Make a list of questions.
Think about the benefits and possible side effects of each option. Talk about your
concerns with your healthcare provider before making a decision.
What are treatment side effects?
Cancer treatment such as chemotherapy and radiation can damage normal cells. This
can cause side effects such as hair loss, mouth sores, and vomiting.
Talk with your healthcare provider about side effects you might have and ways to manage
them. There may be things you can do and medicines you can take to help prevent or
control side effects.
Coping with non-Hodgkin lymphoma
Many people feel worried, depressed, and stressed when dealing with cancer. Getting
treatment for cancer can be hard on your mind and body. Keep talking with your healthcare
team about any problems or concerns you have. Work together to ease the effect of
