Brachytherapy, also called internal radiation therapy, is a type of radiation therapy used to treat several types of cancer, including prostate, breast, and rectal cancers, among others. Brachytherapy involves placing a radioactive material directly inside or next to the tumor. This allows the doctor to use a higher dose of radiation to treat a smaller area and in less time compared to external radiation therapy.
