Brachytherapy

Brachytherapy is a type of cancer treatment where Radioactive seeds (Sealed Sources) are placed in or near a tumour, therefore giving a high Radiation Dose to the tumour while minimising the radiation exposure in the surrounding healthy tissues. Years ago the sources would be manual placed into the tumour site by using tweezers or a needle, where as modern techniques place the source remotely using an afterloader unit.
