Clinical progress and future of targeted therapy for breast cancer

Targeted therapy is one of the most important treatments for breast cancer. In recent years, an increasing number of targeted therapeutic drugs have been developed for different subtypes of breast cancer. The clinical application of these drugs has greatly improved the efficacy and changed the clinical practice for breast cancer. Overcoming drug resistance and developing new drugs that can go beyond the efficacy of traditional targeted drugs are two of the most important research directions in the future.
