The precaution and treatment for cancer become inevitable with the rising of morbidity and mortality. In this article, a promising new methodology for cancer treatment, sono-dynamic therapy (SDT) was introduced. In addition, we extensively reviewed the molec-ular mechanisms of SDT killing cancer and summarized the classification of sonosensi-tizers. At the same time, research progress of SDT indicates that it is possible to become a developing field for cancer treatment in clinical application.
