  Radiation therapy - Wikipedia, the free encyclopedia
Radiation therapy (or radiotherapy) is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis).
Radiotherapy is commonly used for the treatment of tumors.
The most common tumors treated with radiotherapy are breast cancer, prostate cancer, lung cancer, colorectal cancer, head and neck cancers, gynaecological tumors, bladder cancer and lymphoma, although the cancer's stage (progress) and invasion into lymph nodes, as well as other health and (unfortunately) monetary factors affect which treatment will have the greatest possibility of success.

 OCS: Radiotherapy.

 Radiotherapy improves survival after breast-conserving surgery
The omission of radiotherapy after breast-conserving surgery for early-stage breast cancer is associated with higher rates of relapse and a slightly higher mortality rate, according to a study published in the
Many studies have shown that women with early-stage breast cancer who have breast-conserving surgery followed by radiotherapy have similar survival rates as women who have a mastectomy, and those women are also spared the disfiguration of losing their breast.
However, radiotherapy prolongs the length of time that women are treated for breast cancer, the treatment can be costly, radiotherapy facilities are not common in all areas, and there are some side effects to radiotherapy.

Radiotherapy involves the exposure of parts of the body to radiation, beams of high-energy X-rays, gamma rays or particles.
