Breast Cancer Radiation

Also called radiotherapy, radiation treatment directs high-energy x-rays at the cancer cells to kill them or to keep them from growing. Your treatment plan may include radiation therapy after surgery in order to kill any remaining cancer cells in the breast, chest wall or lymph nodes.

Radiotherapy for breast cancer may involve:

  • External Beam Radiation Therapy (EBRT): A machine outside the body delivers radiation to the entire breast with an extra dose or boost given to the tumor site. This is commonly given after a lumpectomy.
  • Brachytherapy: A form of internal radiation therapy, this treatment places tiny radioactive wires, catheters or seeds within the body, in or near the tumor site.
  • Accelerated Partial Breast Irradiation: This therapy delivers radiation only to the lumpectomy site, the most common place for breast cancer to recur. Our radiation oncologists can provide partial breast irradiation in various ways, including EBRT and brachytherapy.
