How is a permanent (low dose rate) brachytherapy done to treat prostate cancer?

ANSWER

A doctor or clinician implants radioactive (iodine-125 or palladium-103) seeds into the prostate gland using an ultrasound for guidance. The number of seeds and where they are placed is determined by a computer-generated treatment plan tailored for each patient. Anywhere from 40 to 100 seeds are commonly implanted. The implants remain in place permanently, and become biologically inert (no longer useful) after a period of months. This technique allows a high dose of radiation to be delivered to the prostate with limited damage to surrounding tissues.
