In estrogen receptor-positiveinfo-icon breast cancer, progesterone receptor-positiveinfo-icon breast cancer and HER2-positive breast cancer, treatment includes medicines that prevent, slow or stop cancer growth by targeting those receptors. But triple-negative breast cancerinfo-icon (TNBC) needs different types of treatments because these cancers are estrogen receptor-negativeinfo-icon, progesterone receptor-negativeinfo-icon and HER2-negative. Chemotherapyinfo-icon has been shown to be the most effective treatment for TNBC.

About 15 to 20 percent of breast cancers are triple-negative.
