What Is a Genetic Predisposition?

Genetic susceptibility is the tendency of different populations and individuals to suffer from polygenic diseases, such as tumors, due to different genetic structures under the influence of external environmental conditions. Some environmental factors and personal living habits can affect the development of tumors. All the factors that can alter the cell cycle, the expression of apoptosis, and the repair of DNA damage are all tumor-induced risk factors, including food, natural and artificial radiation, chemicals and viruses. ^[1]
