Some types of cancer can be treated with internal radiation therapy or brachytherapy. Instead of using radiation beams aimed from a large machine, a radioactive material is placed directly into, or as close as possible to, the cancer.

The material may be left in the body permanently. Seed implant therapy is commonly used to treat prostate cancer.

This type of radiation travels a very short distance in the body (“brachy” is a Greek prefix for “short”), so it harms fewer healthy cells. Internal radiation therapy allows your doctor to give a dose of radiation to a smaller area and in a shorter time than is possible with external radiation treatment.
