Triple Negative Breast Cancer
Over the last 15 or so years, increasing attention has been made to differentiating breast cancers from one another. For much longer, we have known about "ER or hormone positive or negative" cancers. Since pathology has expanded to always include whether a tumor is her2 positive or negative, a parallel thought has identified some tumors as being "triple negative." This means that the cells are ER negative, PR negative, and her2 negative. In terms of treatment, this means that none of the hormonal treatments will be useful; it also means that these cancers often respond especially well to chemotherapy.
