Which of the following cancers has physical activity been shown to help prevent?

• A. Breast, prostate, and lung
• B. Colon, breast, and endometrial
• C. Breast, ovarian, and pancreatic
• D. Endometrial, ovarian, and cervical

Answer: (B)

The association between physical activity and cancer prevention is well-supported by numerous studies, particularly for certain types of cancers. Among the options, colon, breast, and endometrial cancers have all been identified in research as having a potential reduced risk linked to regular physical activity. In the case of colon cancer, physical activity can help lower the risk by promoting healthy digestion and regular bowel movements, which may reduce the time harmful substances are in contact with the intestinal lining. For breast cancer, particularly postmenopausal breast cancer, exercise is believed to influence hormone levels, particularly estrogen, which plays a role in the development of some breast tumors. Similarly, with endometrial cancer, physical activity is thought to help regulate body weight and insulin levels, both of which can be factors in the risk of developing endometrial cancer. Other options do not encompass the same breadth of research linking physical activity to cancer prevention. While cancers such as ovarian, pancreatic, and cervical might have associations with lifestyle factors, the evidence supporting physical activity specifically as a preventive measure is not as strong or conclusive. This makes the connection between physical activity and the prevention of colon, breast, and endometrial cancers the most robust and supported by scientific evidence.
