Introduction: What is Trastuzumab?
Trastuzumab, commonly known by its brand name Herceptin, is a targeted therapy medication primarily used in the treatment of certain types of breast cancer and gastric cancer. It is a monoclonal antibody that specifically targets the human epidermal growth factor receptor 2 (HER2), a protein that can promote the growth of cancer cells. Trastuzumab is often used in conjunction with other treatments to improve outcomes for patients with HER2-positive cancers.
