Chronic Lymphocytic Leukemia (CLL)
Radiation therapy is treatment with high-energy rays or particles to destroy cancer cells. Radiation therapy is seldom part of the main treatment for people with chronic lymphocytic leukemia (CLL), but it may be used in certain situations.
External beam radiation therapy, in which a machine sends a beam of radiation to a specific part of the body, is the type of radiation used most often for CLL. Before your treatment starts, the radiation team will take careful measurements to determine the correct angles for aiming the radiation beams and the proper dose of radiation. Radiation therapy is a lot like getting an x-ray, but the radiation is more intense. The procedure itself is painless. Each treatment lasts only a few minutes, but the setup time − getting you into place for treatment − usually takes longer.
Common short-term side effects of radiation therapy include:
Ask your doctor what side effects you can expect.
