Why might I need a mastectomy?

A mastectomy may be done as part of treatment for breast cancer. Your physician will likely advise you to have a mastectomy if:

  • The tumor is large
  • The tumor involves more than one area of your breast
  • Using radiation therapy is not advised

The size of your breast may also help determine the type of mastectomy that is done.

In some cases, women with a high risk of breast cancer may want to have a mastectomy before cancer develops; this includes women with genes linked to breast cancer, as the BRCA1 or BRCA2 genes. In these cases, a mastectomy is done to try to keep breast cancer from occurring.
