Brachytherapy for prostate cancer

Brachytherapy is a type of internal radiation therapy in which seeds, ribbons, or capsules that contain a radiation source are placed in your body, in or near the tumor. Brachytherapy is a local treatment and treats only a specific part of your body. It is often used to treat cancers of the prostate.

Types of brachytherapy for prostate cancer

There are two main types of brachytherapy for prostate cancer: high dose rate (HDR) and low dose rate (LDR) brachytherapy.

High-dose brachytherapy for prostate cancer

Hight dose rate (HDR) Brachytherapy involves inserting small tubes or catheters into the prostate gland, allowing to deliver a targeted high dose of radiation directly to the tumor site. The procedure is quick and efficient, with the radiation source removed after just a few minutes. This means that patients can return home the same day, minimizing the disruption to their daily lives. HDR brachytherapy is often used in combination with external beam radiation therapy. By combining these treatment modalities, we're able to maximize the effectiveness in treating prostate cancer.

Low-dose brachytherapy for prostate cancer

Low Dose Rate (LDR) brachytherapy is another type of brachytherapy used to treat prostate cancer. LDR involves placing small radioactive seeds, typically made of iodine or palladium, directly into the prostate gland.

How successful is brachytherapy for prostate cancer?

HDR brachytherapy is often used in combination with external beam radiation therapy, and studies have shown that it can be effective in treating prostate cancer, with a high cure rate and low rate of side effects.

  • Effective as a cure
  • Minimized side effects
  • Minimally invasive
  • Reduced treatment times
  • Faster recovery periods
