Product & Procedure

SpaceOAR™ Hydrogel



How SpaceOAR Hydrogel Works

SpaceOAR Hydrogel is designed to help reduce the radiation dose delivered to the rectum during prostate cancer radiation treatments.

When treating prostate cancer patients with radiation therapy, the goal is to destroy the cancer cells while avoiding damage to the surrounding healthy tissue.

Due to the close proximity between the rectum and the prostate, radiation therapy can unintentionally cause rectal toxicity.
