Targeted therapy uses drugs that work in a different way to chemotherapy drugs. While chemotherapy destroys all rapidly dividing cells, targeted therapy attacks specific targets inside cancer cells.
The most widely used targeted therapy for breast cancer is trastuzumab (Herceptin). Other targeted therapies include
- Pertuzumab (Perjeta)
- Ribociclib (Kisqali)
- Transtuzumab emtansine (Kadcyla)
