Cancer biologists use principles of evolution to understand the development of tumors. A population of cells can obtain a mutation after exposure to a carcinogen. In some of the cells, the mutation is not repaired by the cellâs DNA repair machinery and is retained in the genotype. Only a fraction of the cells retaining the mutation become cancerous and only a fraction of those cells have the ability to form a tumor â cells that grow much faster than normal body cells. From the perspective of a tumor-causing cell, what evolutionary processes are at work? From the perspective of the body harboring these tumor cells, what evolutionary processes are at work?
