Which of the following can be a non-genetic factor that influences the development of bowel cancer?

The correct answer is low exercise frequency, as it is recognized as a non-genetic factor that can influence the development of bowel cancer. Lifestyle choices and environmental factors play significant roles in cancer risk, and physical inactivity is linked to various health issues, including certain types of cancer. Regular physical activity is thought to help lower the risk of bowel cancer by contributing to a healthy weight, improving insulin sensitivity, and enhancing digestive health.

In contrast, age is a non-modifiable risk factor associated with an increased risk of bowel cancer, as older individuals tend to have a higher incidence of the disease. Smoking is also a recognized risk factor for several cancers, including bowel cancer, as it introduces carcinogens into the body. High fiber diets, while important for maintaining gut health and potentially reducing cancer risk, are considered beneficial rather than a risk factor, which makes them less relevant in the context of identifying a non-genetic factor that increases the likelihood of developing bowel cancer.
