Exercise lowers the risk of several cancers by 20%.
Exercise as Medicine: The Numbers
Regular physical activity is independently associated with a 20-25% reduction in the risk of at least 13 cancer types.
The Biological Mechanisms
Exercise reduces circulating insulin and IGF-1, reduces chronic inflammation via cytokine modulation, stimulates NK (natural killer) cell activity, and improves gut motility.
Exercise During and After Treatment
Exercise during chemotherapy and radiation reduces treatment-related fatigue by 40-50% and preserves muscle mass critical for tolerating treatments.
How Much Is Enough?
adults should aim for at least 150-300 minutes/week of moderate-intensity activity (brisk walking, swimming, cycling) or 75-150 minutes/week of vigorous activity.
