Jay K. Harness, MD: When we use the term ‘prophylactic’ in talking about breast, we are talking about a prophylactic mastectomy, in other words, the removal of a healthy breast. Why in the world would we ever want to do that? Well, part of this is driven now by patient choice. There are patients who say, “Gee, I have had a cancer on one side and I have had a mastectomy on that side. I never want to deal with this again. I simply want the other breast off.”

Another example of the use of prophylactic mastectomy, or plural mastectomy (meaning both breasts), would be in somebody who is gene-positive, who know that their chance of getting a breast cancer is 80%, and this is a preemptive strike, if you will, to prevent ever getting breast cancer.

In that sort of circumstances, prophylactic mastectomy is prior to ever having a breast cancer and lowers the gene-positive patient’s chance of dying from breast cancer by a little greater than 95%. There’s no mastectomy on the planet that can remove 100% of all breast tissue, but greater than 99% is removed with a mastectomy – prophylactic or not.
