Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors and damages their DNA. It is one of the effective ways to kill cancer cells. Medical Linear Accelerator (TrueBeam®STX System) is an external beam radiation therapy. External Beam Radiation Therapy (EBRT) involves targeted radiation beams being delivered from outside the body. It gives a large dose of radiation to a small tumor area, usually in one session. It accurately targets the tumor anywhere on the body where the surgery is not feasible. AIG Hospitals have the most advanced LINAC-TrueBeam®STX.
