Brachytherapy is a mode of cancer treatment by insertion of radioactive implants directly into the tumour, thereby allows delivery of higher doses of radiation to tumours and sparing toxicity to surrounding normal tissues. It is commonly used as an effective treatment in cervical, head and neck, endometrial, vaginal, breast, esophageal, skin and sarcomas.
