This type of treatment also involves high doses of radiation and treats the cancer by placing radioactive material directly into the prostate. Depending on your situation, brachytherapy may be used alone, combined with external beam radiotherapy, and/or hormone therapy. Radiation dose from brachytherapy can be delivered at different rates – both low-dose-rate (LDR) or high-dose-rate (HDR).
Temporary high-dose rate (HDR) brachytherapy - This is a new and highly effective type of brachytherapy treatment. Recent studies have shown that the HDR technique improves cure rates for prostate cancer while also sparing nearby normal tissue. A single small radioactive dose is placed in a narrow tube called a catheter. The catheter is then placed into the prostate by your radiation oncologist. You will be under anesthesia and will not feel pain. Special computer software controls where and for how long the radiation is delivered. This helps target the prostate cancer very precisely. The catheter is then removed. Once the treatment is complete, there is no radioactivity left in your body and there is no need for radiation safety precautions. You usually can go home shortly after the procedure, and you can continue your normal activities with few restrictions.
