Which lifestyle factor is associated with an increased risk of bowel cancer?

Low physical activity is associated with an increased risk of bowel cancer due to several factors. Engaging in regular physical exercise helps to maintain a healthy weight, supports digestion, and enhances the immune system, all of which can contribute to a lower risk of developing various cancers, including bowel cancer. Conversely, low physical activity may lead to obesity and metabolic changes that can promote tumor growth and development in the bowel.

Moreover, physical inactivity can affect bowel transit time and the composition of gut microbiota, potentially leading to a higher likelihood of pathological changes in the colon. Therefore, maintaining a physically active lifestyle is imperative for reducing the risk of bowel cancer. In contrast, regular exercise and an active lifestyle are protective factors, and diets rich in fruits, vegetables, and whole grains have beneficial effects on gut health and cancer risk, making those lifestyle choices less associated with increased risk.
