Internal radiation therapy (RTi), also known as brachytherapy, is a form or RT that puts the radioactive material inside the patient either via a catheter or a needle. In terms of its placement, RTi may be administered as intracavitary or interstitial. In the case of intracavitary, the radioactive material is placed inside a cavity in the body such as in the rectum or uterus; in the case of interstitial, the radioactive material is placed on/near the cancer but not inside a body cavity. The most common form of brachytherapy involves the placement of seeds inside the body involving differing durations and radioactivity. Each seed is approximately the size and shape of a small grain of rice.
