Radiation therapy (also called radiotherapy) is a treatment for cancer that uses high doses of radiation to kill cancer cells and stop them from spreading. Low doses of radiation are used in common activities such as X-rays of your teeth or bones, yet when given in high doses, radiation kills or slows the growth of cancer cells.
Radiation therapy may be used at
- Before surgery, to shrink a cancerous tumor (neoadjuvant therapy)
- After surgery, to stop the growth of any remaining cancer cells (adjuvant therapy)
- In combination with other treatments, such as chemotherapy, to
- In advanced cancer to alleviate symptoms caused by cancer
Radiation is delivered differently depending on the nature of the cancer. It can be delivered by an external beam using a linear accelerator (linac) or internally, where a
Radiation therapy effectively treats many types of cancer, some of which include breast, colorectal, head and neck, prostate and gynecologic. In addition, radiation therapy may also be used to shrink tumors to reduce pain in patients with advanced cancers.
Types of treatment:
The ultimate goal of radiation therapy is to use enough radiation to kill the cancer cells while minimizing damage to healthy tissue. Radiation therapy can be delivered either internally or externally. Depending on the location of your cancer, its size and type, you may receive either or both methods of treatment. If external beam radiation therapy is used, a machine will direct radiation at the cancer – much like a routine x-ray. Internal radiation, or brachytherapy, on the other hand, inserts radioactive materials, such as seeds, into your body.
