How High-dose-rate Brachytherapy (HDR) Works

HDR brachytherapy is a dependable and highly developed form of internal radiation therapy delivered through catheters to the exact site of a cancerous tumor. This procedure is typically repeated over several treatments to quickly deliver a high dose of radiation to the tumor.

Compared to low-dose-rate radioactive seeds that are implanted for extended periods of time, the higher doses used in HDR brachytherapy deliver equivalent radiation in just a few minutes by inserting and then removing the radioactive material. HDR brachytherapy may be given as the only treatment or it may be combined in a treatment plan with external radiation therapy.

HDR treatment is often faster than other types of treatment, and can be performed on an outpatient basis. Most importantly, the precision and limited exposure to healthy tissue HDR provides translates to excellent success rates for certain types of cancers.
