Radiation therapy uses high energy x-rays to destroy cancer cells. A radiation oncologist will customize the treatment dose for individual needs. The goal is to try and kill as much cancer while minimizing harm to healthy tissue. Radiation therapy is generally most effective when used in combination with other treatments, such as surgery and chemotherapy. It may be used to destroy remaining cancer cells after surgery, or rarely, as an alternative for people who can not tolerate surgery.
There are different types of radiation therapy, but external beam radiation is used to treat bladder cancer. In external beam radiation therapy, radiation is produced by a machine positioned outside the body. Short bursts of x-rays are directed at the cancer. The radiation oncologist will direct the radiation beam to affect as much cancer as possible.
Complications of radiation therapy to the pelvic area may include:
A variety of treatments are available to help manage side effects of radiation therapy, such as dry, irritated skin, nausea, vomiting, diarrhea, and fatigue due to anemia. Sometimes adjustments to treatment doses may also be possible. The earlier side effects are addressed, the more likely they will be controlled with a minimum of discomfort.
