Ado-trastuzumab emtansine injection is used to treat HER2-positive metastatic breast cancer (cancer that has spread to other parts of the body) in patients who have already received other medicines that did not work well. HER2 protein is produced by some breast tumors. Ado-trastuzumab emtansine interferes with the growth of this protein which also prevents tumor growth. The tumor cells will then be destroyed by the body.
