Brachytherapy, also known as sealed source radiotherapy or endocurietherapy, is a form of radiotherapy where a radioactive source is placed, under the guidance of imaging, within or next to the area requiring treatment.

Brachytherapy is commonly used to treat localised prostate cancer, breast cancer (often post-lumpectomy 1), cervical cancer and cancers of the head and neck.

Treatment and prognosis


Side effects associated with brachytherapy treatment of prostate cancer include:

  • urinary symptoms, often short-lived
  • infertility or impotency (6-50%)
  • migration of seeds out of the treatment region
    • therefore important to filter urine to recover the radioactive seeds
