Advances in the targeted therapy for breast cancer

In 2022, 670000 people died because of breast cancer (BC). Notwithstanding their age and gender, women make up about half of the total number of instances of BC without any specific risk factors. In 157 out of 185 nations in 2022, BC will be the most frequent cancer among women. With the continuous progress of research, BC has achieved great breakthroughs, such as the introduction of BC immunotherapy, which is a revolutionary treatment for some patients; In addition is the introduction of antibody-coupled drugs (ADCs) that can target the delivery of potent chemotherapy drugs into breast cancer cells. This paper analyzes the treatment of some targets in BC, and obtains the application effect of some new drugs in breast cancer, which buys time for clinical treatment such as surgery. However, there are still some drugs with unclear effect on breast cancer treatment, and some drugs are only used alone. Future studies can pay more attention to the aspects of drug combination therapy.
