Brachytherapy - Also known as internal radiation therapy, implant radiation therapy, interstitial radiation therapy or seed implantation, brachytherapy involves the direct placement of radioactive material (seeds or pellets) into or near a tumor. Brachytherapy is commonly used to treat prostate, breast, lung, and esophageal cancers. The greatest potential advantage of brachytherapy in cancer treatment is that it delivers a highly concentrated dose of radiation directly to the tumor to help shrink and destroy cancerous cells, while limiting radiation exposure to healthy surrounding tissue. One type of brachtherapy, called High-Dose Rate (HDR) brachytherapy, offers a precise computer-controlled internal radiation treatment that takes only minutes, rather than days for low-dose brachytherapy.
