    Breast Cancer - Medications

    Medicines are used to treat breast cancer and also to help relieve side effects of treatment.

    The side effects of targeted therapies will depend on the type of medicine that is given. They include nausea, vomiting, and diarrhea. Some medicines can also cause side effects that are more serious.
