White blood cells called lymphocytes are found in lymph tissues. Most lymphomas start in a type of white blood cells called B lymphocytes, or B cells.
For most patients, the cause of this cancer is unknown. However, lymphomas may develop in people with weakened immune systems. For example, the risk of lymphoma increases after an organ transplant or in people with HIV infection.
There are many different types of non-Hodgkin's lymphoma. It is classified according to how fast the cancer spreads.
According to the American Cancer Society, a person has a 1 in 50 chance of developing non-Hodgkin's lymphoma. Most of the time, this cancer affects adults. However, children can get some forms of lymphoma. High-risk groups include those who have received an organ transplant or who have a weakened immune system.
This type of cancer is slightly more common in men than in women.
Non-Hodgkin's lymphoma can cause a variety of symptoms. Symptoms depend on what area of the body is affected by the cancer and how fast the cancer is growing.
Symptoms may include:
Coughing or shortness of breath may occur if the cancer affects the thymus gland or lymph nodes in the chest, which may put pressure on the windpipe (trachea) or other airways.
Some patients may have abdominal pain or swelling, which may lead to a loss of appetite, constipation, nausea, and vomiting.
If the cancer affects cells in the brain, the person may have a headache, concentration problems, personality changes, or seizures.Calling your health care provider
Call your health care provider if you develop symptoms of this disorder.
If you have non-Hodgkin's lymphoma, call your health care provider if you experience persistent fever or other signs of infection.
Treatment primarily depends on:
Radiation therapy may be used for disease that is confined to one body area.
Chemotherapy is commonly used as the main form of treatment. Most often,multiple different drugs are used in combination together.
Another drug, called rituximab (Rituxan), is often used to treat B-cell non-Hodgkin's lymphoma.
Radioimmunotherapy may be used in some cases. This involves linking a radioactive substance to an antibody that targets the cancerous cells and injecting the substance into the body.
People with lymphoma that returns after treatment or does not respond to treatment may receive high-dose chemotherapy followed by an autologous bone marrow transplant (using stem cells from yourself).
Additional treatments depend on other symptoms. They may include:
Low-grade non-Hodgkin's lymphoma usually cannot be cured by chemotherapy alone. However, the low-grade form of this cancer progresses slowly, and it may take many years before the disease gets worse or even requires any treatment.
Chemotherapy can often cure many types of high-grade lymphoma. However, if the cancer does not respond to chemotherapy drugs, the disease can cause rapid death.
The doctor will perform a physical exam and check body areas with lymph nodes to feel if they are swollen. Tests to diagnose and stage non-Hodgkin's lymphoma include:
