Prostate brachytherapy (brak-e-THER-uh-pee) is a form of radiation therapy used to treat prostate cancer. Prostate brachytherapy involves placing devices containing radiation in the prostate gland close to the cancer cells.

Prostate brachytherapy procedures vary based on the type of radiation you'll receive. Temporary prostate brachytherapy involves placing radioactive wires in the prostate gland for several minutes before the wires are removed. Permanent prostate brachytherapy involves placing radioactive seeds in the prostate gland permanently, where they slowly release radiation.

The goal of prostate brachytherapy is to place the radiation close to the cancer cells, where the radiation can kill the cancer cells while causing less damage to healthy tissue nearby. Prostate brachytherapy side effects can include difficulty urinating and erectile dysfunction.
