Low Dose Rate Brachytherapy (LDR)
Low Dose Rate Brachytherapy is a type of radiation therapy used to treat prostate cancer. It works by damaging the cancer cells and making it hard for them to multiply. With brachytherapy, your healthcare provider will place tiny radioactive implants (also called seeds) inside your prostate. Each one is about the size of a sesame seed. The seeds will give off radiation for a period of time and then stop. They’ll stay in your prostate for the rest of your life. The radioactive seeds will be made of radioactive iodine (I-125) or palladium (Pd-103) and covered with titanium. Your radiation oncologist will tell you which is the best choice for you. Your healthcare provider will place 50 to 125 seeds in your prostate. How many they place depends on how big your prostate is.
