Lymphoma refers to a malignancy of the lymphatic system. The lymphatic system is a network of nodes (knots of tissue) connected by vessels. Together, the lymph nodes drain fluid and waste products from the body. The lymph nodes act as tiny filters, removing foreign organisms and cells.
Lymphocytes, are a type of white blood cell that helps fight infections caused by bacteria, viruses, or fungi. The lymph node function is to prevent infections from entering the bloodstream. When the lymphatic...
With external radiation, X-rays from a machine are aimed at the part of the body with the cancer.
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 a person is getting a stem cell transplant.
What To Expect After Treatment
Side effects are common but generally go away when treatment is
finished. They include:
Low blood counts, which may increase the risk
of infection and bleeding.
For non-Hodgkin's lymphoma (NHL), radiation may be used alone or in combination
with other treatment options, such as chemotherapy. Radiation is also

Radiation therapy is used to help keep an acute leukemia from
spreading to the central nervous system (CNS prophylaxis). It is also used to
treat recurrent leukemia that has spread to the brain or spinal cord.
How Well It Works
For some stages of leukemia and non-Hodgkin's lymphoma
(NHL), radiation therapy works well when used alone. But it may be used in combination with chemotherapy, depending on the type and the stage of the cancer.
The short-term side effects of radiation therapy are common but usually get better
and go away when treatments stop. These side effects depend on the area of the body
affected by treatments and may include:
Low blood counts, which may increase your risk
of infection or bleeding.
Hair loss in

of the skin.
The long-term side effects of radiation therapy depend on what part of your body was treated, how much radiation you were given, and how long your treatment lasted. For example, radiation therapy to the pelvis may cause permanent
sterility. Other long-term side effects may include brain changes, joint problems, lymphedema, mouth problems, and other cancers. These side effects depend on whether you also had chemotherapy.
