High Dose Rate (HDR) Brachytherapy

What is High Does Rate (HDR) Brachytherapy?

HDR brachytherapy is a type of internal radiation therapy that is able to deliver high doses of radiation directly to the tumor, sparring much of the surrounding healthy tissue. HDR procedures involve the placement of a radioactive source in or near the area to be treated. Many types of cancer can be treated with HDR, including breast cancer, cervical cancer and prostate cancer.

What are the advantages of HDR?

This technique allows for shorter treatment time and less radiation exposure to healthy tissue by placing a temporary radioactive source in or near the area to be treated. This ensures that doses of radiation are delivered in short periods of time – for example, partial breast treatment (for those who meet the criteria) is given for five days versus the traditional six weeks - to cancerous tissue while minimizing exposure to healthy tissue.

How does HDR work?

In HDR Brachytherapy radiation is delivered to the cancerous tumor through an applicator that is placed in or near the tumor inside the body. Using computer software, physicians are able to determine how and where the radiation should be administered. The radiation is delivered directly to the tumor through the applicator, allowing greater amounts of radiation to be delivered over a shorter amount of time while leaving the surrounding healthy tissue unbothered.
