The term triple-negative breast cancer refers to the fact that the cancer cells don’t have estrogen or progesterone receptors and also don’t make too much of the protein called HER2. For some people, triple-negative breast cancer develops due to a mutation in the BRCA1 or BRCA2 gene. “So you will pick up many more positive cases by looking at the immune cell component,” Dr. Tozbikian said.

Knowing whether breast cancer is triple … About 10-20 percent of breast cancers are triple-negative breast cancers.

Background: Triple-negative (TN) breast cancers lack estrogen receptor (ER), progesterone receptor (PR), and HER2/neu amplification (HER2). We have learned a lot - that if someone got some chemotherapy before surgery and at the time of surgery, if we still see there is cancer in the breast, then we do know that giving additional therapy after surgery is important. These are: Progesterone receptor-positive and estrogen receptor-positive breast cancers are the most common. Occasionally, there may be a change in receptor status.
