Which factor does NOT typically increase cancer risk?

Regular screenings do not increase cancer risk; in fact, they help in the early detection and prevention of cancer. Screenings are proactive measures that allow for the identification of cancer at an earlier and often more treatable stage. By detecting abnormalities before they progress to cancer, regular screenings can significantly reduce the risk of cancer-related complications and mortality.

In contrast, genetic mutations, environmental pollutants, and aging are all well-documented factors that can increase the risk of developing cancer. Genetic mutations can drive the uncontrolled growth of cells, leading to tumor formation. Environmental pollutants can introduce carcinogenic substances into the body, increasing the likelihood of cellular changes that lead to cancer. Aging is associated with the accumulation of genetic damage over time and the decline in the effectiveness of cellular repair mechanisms, both of which contribute to a higher cancer risk as individuals grow older.
