Breast Cancer: Targeted Therapy
Targeted therapies are drugs that find and kill specific types of cancer cells. Targeted therapies may have fewer side effects than other types of treatment, such as chemotherapy. Generally, there are two main ways to target breast cancer cells:
- Endocrine therapy: Blocking or lowering female hormones
- Biologic or HER2-targeted therapy: Stopping the human epidermal growth factor receptor 2 (HER2) pathway
- New targeted drugs: New drugs are being developed every year; ask your doctor if you may be eligible for one of these drugs through a clinical trial.
