Radiotherapy for secondary breast cancer

Radiotherapy uses X-rays to destroy cancer cells in some parts of the body. Radiotherapy is a localised treatment, which means it only treats the area of the body it’s aimed at.Radiotherapy may be used to treat different parts of the body that are affected by secondary breast cancer.

If secondary breast cancer has spread to the bones, radiotherapy may be used:

  • to relieve bone pain
  • to prevent or treat fractures
  • to prevent and treat cancer in or around the spine that may be putting pressure on the spinal cord.

If secondary breast cancer has spread to the brain, radiotherapy may be used:

  • after surgery to treat cancer in one area of the brain
  • instead of surgery to relieve symptoms of cancer in the brain.

If secondary breast cancer has spread to other parts of the body, radiotherapy may be used:

  • to relieve pain or swelling or to reduce the size of enlarged lymph nodes.
