IMRT :
Intensity-modulated radiation therapy (IMRT) is a type of radiation treatment for cancer and is a form of external beam radiation therapy. It uses a machine called LINAC (linear accelerator) that directs the radiation in the form of high energy X-ray beams to destroy the cancer cells. It never touches the body. It kills and shrinks the size of the tumor to minimize the damage to the nearby healthy tissue. It destroys the cells more precisely within the confined treatment area. It is also used to treat cervical cancer, lung cancer, colon cancer, breast cancer, stomach cancer, prostate cancer, and uterine cancer. It is usually performed by a team that includes a radiation oncologist, radiation therapist, physicist, and dosimetrist. It uses the tumor image to design the energy that is capable of destroying the cells. Each beam can be adjusted at a different strength. The advantages of IMRT include precision and protects healthy tissue from radiation exposure.
