Exercise to Reduce Risk of These Cancers

Exercise to Reduce Risk of These Cancers

Anti-Cancer Benefits of Exercise

A large multinational team of researchers analyzed data to determine the potential for exercise to reduce the risk of cancer. Research team members from the National Cancer Institute, Brigham and Women’s Hospital and the Harvard Medical School, The Karolinska Institutet in Sweden, George Washington University School of Public Health, The University of Melbourne School of Public Health, and other prestigious research institutions, reviewed data from  755,000+ participants who had been followed for over ten years. There were 50,529 cases of cancer among the population. Of the fifteen types of cancer studied, individuals meeting guidelines for regular exercise (150 minutes a week of moderate aerobic exercise, or 75 minutes of vigorous aerobic exercise) had a lower risk of seven cancers. Specifically, colon, breast, endometrial, kidney, myeloma, liver and non-Hodgkin lymphoma.

Importantly, the amount of risk reduction varied among the cancer types and differed between men and women. This is worth emphasis: regular exercise didn’t reduce cancer risk uniformly. Risk reductions by type:

  • Colon 8-14% in men,
  • breast 6-10%,
  • endometrial 10-18%,
  • kidney 11-17%,
  • myeloma 14-19%,
  • liver 18-27%,
  • non-Hodgkin lymphoma 11-18% in women.

Exercising more than the guidelines reduced the risk of colon, endometrial and breast cancer, but not the others. If you have reasons to believe you are at higher risk of one of those types, consider a more vigorous exercise program. (As always, a reminder that no one at Big Brain Place is a medical doctor. Talk to yours and take her advice before you start running ten miles to a CrossFit Box.)
