Which of the following is a recommended method for cancer prevention related to lifestyle?

Regular exercise is widely recognized as an effective method for cancer prevention as part of a healthy lifestyle. Engaging in physical activity has multiple benefits, including maintaining a healthy weight, improving metabolic health, and reducing inflammation—all of which are associated with a lower risk of developing various cancers. Regular exercise can also enhance immune function and may help improve the body's ability to respond to and repair cellular damage, which is pivotal in cancer prevention.

Research supports that individuals who are physically active tend to have a lower risk of several types of cancer, including breast and colon cancers. The recommended amount of physical activity is generally at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise weekly. This lifestyle modification can be easily implemented and offers a range of additional health benefits beyond cancer prevention, such as improved cardiovascular health and enhanced mental well-being.

In contrast, while caloric restriction can play a role in weight management and may have some cancer prevention benefits, it is less emphasized as a standalone lifestyle recommendation compared to regular exercise. Nutrient supplementation may be beneficial for specific deficiencies but cannot replace the protective effects of healthy dietary habits and physical activity. Additionally, mailing annual health reports does not influence lifestyle choices directly related to cancer prevention.
