Physical activity and cancer: an umbrella review of the literature including 22 major anatomical sites and 770 000 cancer cases.

Abstract in brief

• This umbrella review analyzed multiple studies to assess how physical activity impacts the risk of developing or dying from various types of cancer, covering 22 different cancer sites and over 770,000 cases.
• The review found strong evidence that physical activity is linked to a reduced risk of colon and breast cancer, especially with recreational activity for colon cancer and overall activity for breast cancer, but evidence for other cancers was less consistent and more uncertain.
• Overall, while physical activity appears to lower the risk for some cancers, especially colon and breast, the evidence for other sites is mixed and suggests potential biases or uncertainties in the existing research.]
