Treatment of Triple-negative Breast Cancer
In triple-negative breast cancer (TNBC), the cancer cells don’t have estrogen or progesterone receptors, nor do they have too much of the HER2 protein. Because the cancer cells don't have these proteins, hormone therapy and drugs that target HER2 are not helpful, so chemotherapy (chemo) is the main systemic treatment option. And even though TNBC tends to respond well to chemo initially, it also tends to come back (recur) more frequently than other breast cancers.
