Exercise can lower the risk of which types of cancer?

The correct answer acknowledges that regular exercise has been shown through various studies to lower the risk of specific types of cancers, particularly colon cancer, breast cancer, and reproductive cancers (such as endometrial and ovarian cancer). Engaging in regular physical activity can help maintain a healthy weight, reduce inflammation, and enhance immune function—factors which are all associated with a decreased risk of these cancers.

Colon cancer, for instance, has a particularly strong relationship with physical activity; studies have indicated that individuals who are more physically active have a significantly lower risk of developing this type of cancer. Similarly, research has demonstrated that exercise can reduce breast cancer risk by helping to balance hormone levels and facilitate a healthier body composition.

While exercise might play a role in overall cancer prevention, it does not guarantee a reduced risk for all types of cancer, such as lung and skin cancers. These cancers are influenced by other factors beyond physical activity, including environmental and genetic influences. Thus, while exercise provides substantial benefits regarding specific cancers, it does not necessarily apply universally to all cancers.
