David Hanahan

David Hanahan is a scientist renowned for his research on cancer biology. He, along with colleagues, identified six key biological changes—called "hallmarks"—that enable cancer cells to grow uncontrollably and spread. These hallmarks include sustaining growth signals, evading cell death, and promoting blood vessel formation, among others. His work helps scientists understand how cancers develop and persist, guiding the development of targeted treatments. Hanahan’s contributions have significantly shaped modern oncology by providing a framework for studying cancer’s complexities at the cellular and molecular levels.
