Triple-negative breast cancer

Triple-negative breast cancer (TNBC) is a type of breast cancer that lacks three common markers found in other breast cancers: estrogen receptors, progesterone receptors, and HER2 protein. This means that TNBC does not respond to hormonal therapies or treatments that target HER2. It tends to grow more quickly and has fewer treatment options compared to other types of breast cancer. TNBC is more common in younger women and those with a BRCA1 gene mutation. Treatments typically include surgery, chemotherapy, and radiation, depending on the stage and individual circumstances. Early detection and personalized treatment are crucial for better outcomes.
