High-Dose Rate Brachytherapy

What is High-dose rate (HDR) brachytherapy?

High-dose rate (HDR) brachytherapy is a type of internal radiation therapy that delivers radiation from implants placed close to, or inside the tumor(s) in the body.
Because cancer often affects organs and other essential structures, it is important for radiation treatment to be tightly focused on tumors to minimize serious side effects. This technique ensures the maximum radiation dose is given to cancerous tissues, while minimizing exposure to the surrounding healthy tissue.
