Brachytherapy: treatment from inside

Cross-sectional diagram of a tumour with a sealed implant at the centre emitting short-range beta particles that stop within the tumour, leaving surrounding healthy tissue largely unaffected Brachytherapy is internal radiotherapy: tiny sealed radioactive sources are placed inside or immediately next to a tumour. Because the source is very close to the cancer cells, the radiation dose is concentrated where it is needed.
