Quizplus · Accepted Answer

Trastuzumab works by targeting the HER-2/neu protein, which is overexpressed in some types of breast cancer cells. By binding to the HER-2/neu protein, trastuzumab can inhibit the proliferation of cancer cells that overexpress this protein, thereby helping to treat breast cancer. Choices B and C describe mechanisms of action for other types of breast cancer therapies that target hormonal pathways, and choice D describes a more general approach to targeting metastatic cancer, not specific to the mechanism of action of trastuzumab.
