Some breast and prostate cancers require certain hormones to grow. Starve cancer of hormones it needs to grow.Some targeted therapies can cause cancer cells to go through this process of cell death, which is called apoptosis. But, cancer cells have ways of avoiding this dying process. Healthy cells die in an orderly manner when they become damaged or are no longer needed. Cells that don’t have the target will not be harmed. Once these monoclonal antibodies attach to targets on the surface of cancer cells, the cells take up the cell-killing substances, causing them to die. Some monoclonal antibodies are combined with cell-killing substances such as toxins, chemotherapy drugs, or radiation. Deliver cell-killing substances to cancer cells.Targeted Therapy Improves Survival for Metastatic “HER2-Low” Breast CancerĮnhertu expected to become new standard for treating metastatic breast cancer with low HER2 protein levels. ![]() Learn more about angiogenesis inhibitors. Or, if a tumor already has a blood supply, these treatments can cause blood vessels to die, which causes the tumor to shrink. Without a blood supply, tumors stay small.
