    Types of Breast Cancer

    Triple-Negative Breast Cancer

    Some breast cancers -- between 10% and 20% -- are known as “triple negative” because they don’t have estrogen and progesterone receptors and don’t overexpress the HER2 protein. Most breast cancers associated with the gene BRCA1 are triple negative.

    These cancers generally respond well to chemotherapy given after surgery. But the cancer tends to come back. So far, no targeted therapies have been developed to help prevent cancer returning in women with triple-negative breast cancer. Cancer experts are studying several promising strategies aimed at triple-negative breast cancer.
