Breast cancer staging

Once your health care team knows you have breast cancer, they will do more tests to stage it. Staging is a tool the team uses to find out how advanced the cancer is. The stage of the cancer depends on the size and location of a tumor, whether it has spread, and how far the cancer has spread.

Your health care team uses staging to help:

  • Decide the best treatment
  • Know what kind of follow-up will be needed
  • Determine your chance of recovery (prognosis)
  • Find clinical trials you may be able to join
