Brachytherapy is a special form of internal radiation therapy where a radioactive source is placed beside or inside the tumour, to deliver radiation to small areas over a period of time. Brachytherapy is commonly used for, but not limited to, the treatment of gynaecological, prostate and skin cancers.
Brachytherapy can be administered through either a permanent radioactive seed implant (Low Dose Rate “LDR” treatment) or through moving a radioactive source in and/or around the cancer (High Dose Rate “HDR” treatment). With HDR treatment, the radioactive source is retracted out of the body once depositing the prescribed dose by the clinical oncologist. Our clinical oncologists will discuss which treatment is suitable for you.
The benefits of brachytherapy compared with other forms of radiation treatment include:
- Ability to deliver high localised dose
- Rapid fall off of dose
- Ability to sculpt dose to shape of tumour or organ of interest
