Tiny radioactive seeds, about the size of a grain of rice, are permanently placed inside the tumor.1 The seeds give out low levels of radiation for a few months, killing the cancer cells. LDR brachytherapy is a very effective treatment for prostate cancer.
In contrast to low dose rate brachytherapy (seed implants), no radioactive material is left in the prostate after treatment.
HDR brachytherapy has been shown to be an effective treatment for intermediate and high risk prostate cancer.2 It is often given in combination with external beam radiotherapy (EBRT), as it can provide an additional dose of radiotherapy to help prevent the cancer from returning.
Some centres offer HDR brachytherapy as the sole method of treatment as it is very effective and quick treatment, making it very convenient for many patients. Your doctor will be able to advise you if HDR brachytherapy is a possible treatment option for you.
In high risk and intermediate risk disease a combination of External Beam Radiotherapy (EBRT) and brachytherapy may be advised by your doctor. Cure rates (measured by monitoring patients' PSA levels) have been shown to be improved when brachytherapy was added to EBRT3,4,5
