Radiation therapy uses high-energy radiation to shrink or eradicate tumor cells. Radiation therapy kills cancer cells by damaging their DNA, and cancer cells whose DNA is damaged beyond repair stop dividing or die. There are a variety of types of radiation used for cancer treatments. The radiation may come from a machine outside of the body (linear accelerator - LINAC), or it may come from radioactive material placed in the body (brachytherapy).
Patients may receive radiation therapy before, during or after surgery and/or chemotherapy, depending the on the type and site of cancer being treated.

The number of treatment sessions depends on many factors, including the total radiation dose that will de delivered. Additional items the physician will consider are type and size of the cancer, location in the body, proximity of the tumor to normal tissues that are sensitive to radiation, patient’s general health and medical history and if the patient will have any other type of cancer treatment in india (e.g., Chemotherapy).

Radiation therapy effectively treats cancer by using high-energy beams of radiation to pinpoint and destroy cancerous cells. Although radiation therapy is similar to an x-ray, the dose of radiation in cancer treatment is much stronger and is given over a longer period of time.
Various forms of radiation therapy are available; the two basic types are external beam radiation and internal radiation, or brachytherapy.
