How Do Environmental Factors Interact with Genetic Susceptibility?
Genetic susceptibility does not act in isolation; it interacts with environmental factors to influence disease risk. For instance, an individual with a genetic predisposition to lung cancer may never develop the disease if they avoid smoking. Conversely, someone without a genetic predisposition might still develop lung cancer if exposed to high levels of pollutants. This interaction is often studied through gene-environment interaction research, which helps to identify how different factors combine to influence health outcomes.
