Herceptin (Trastuzumab)

Herceptin, or trastuzumab, is a medication used primarily to treat certain types of breast cancer that are HER2-positive, meaning the cancer cells have too much of the HER2 protein. This protein promotes cancer cell growth. Herceptin works by targeting and blocking HER2, slowing down or stopping the growth of these cancer cells. It can be used alone or in combination with other treatments, such as chemotherapy. By specifically focusing on HER2-positive cancers, Herceptin helps improve treatment outcomes for many patients, making it a vital option in targeted cancer therapy.
