How much physical activity is recommended weekly to reduce the risk of colon cancer?

• A. 1-2 hours
• B. 3-4 hours
• C. 5-6 hours
• D. Less than 1 hour

Answer: (B)

The recommendation of 3-4 hours of physical activity per week is rooted in extensive research linking regular exercise to a lower risk of several types of cancer, including colon cancer. Engaging in moderate to vigorous physical activity can help maintain a healthy weight, improve digestive health, and enhance the body's immune function, all of which contribute to cancer prevention. Physical activity is thought to play a role in reducing colon cancer risk through various mechanisms, such as improving insulin sensitivity, modulating hormones, and decreasing inflammation. The guideline to aim for approximately 150-300 minutes of moderate-intensity aerobic activity or 75-150 minutes of vigorous-intensity activity per week aligns with the recommendation of 3-4 hours for optimal health benefits. In contrast, options suggesting less physical activity do not provide the same level of benefit in terms of cancer risk reduction. Engaging in only 1-2 hours, or even less than 1 hour, may not sufficiently stimulate the physiological changes necessary for significant protection against colon cancer. Thus, the higher range of physical activity recommended is critical for achieving the desired health outcomes.
