Prostate seeds refers to a form of low-dose-rate (LDR) brachytherapy, which is a type of radiation therapy in which multiple, small, radiation-emitting devices are implanted directly into the prostate permanently. The procedure is conducted with the patient unconscious, and it is a one-time procedure. The dose to the prostate can be high and will give very little dose to normal organs at a distance from the prostate. The procedure is one of the many options of treatment available for prostate cancer.
