Types of Radiation Oncology Treatment

The Department of Radiation Oncology at the Samuel Oschin Comprehensive Cancer Institute offers radiation therapy. The type of therapy a patient receives depends on the type of cancer, its stage and where it is located.

The center uses the latest technologies that are designed to keep the radiation dose as low as possible to minimize unpleasant side effects. The treatments include:

Brachytherapy

Brachytherapy is a form of radiotherapy that places a radiation source (radioactive seeds) inside or next to the area needing treatment. It allows for the precise delivery of high-dose radiation to the targeted area while preventing healthy tissue from unnecessary exposure. Common sites for which brachytherapy treatment is considered are:

  • Gynecological—cervical, uterine, vaginal, vulvar
  • Prostate—definitive, salvage (re-irradiation)
  • Breast—after lumpectomy, salvage (re-irradiation), during surgery (intraoperative radiation therapy)
  • Skin—basal cell, squamous cell, keloids
  • Gastrointestinal—esophageal (re-irradiation), cholangiocarcinoma, liver (hepatocellular carcinoma)/metastasis
  • Sarcoma
