Exercise Matters

If there's one thing most experts agree on when it comes to lowering your risk of cancer, it's that exercise works.
People who are overweight have higher levels of hormones such as insulin and estrogen circulating through their bodies, says Doyle, M.S. R.D. Exercise helps reduce these hormones and lowers the risk of cancers associated with them, such as breast and colon cancer.
Being physically active also helps move food through your GI tract faster, which keeps your GI tract healthy and efficient and prevents irritants from lingering longer than they should.
All adults should be at least moderately active for 30 minutes, 5 days a week. Moderate exercise means being able to walk one mile in about 15-20 minutes. Walking faster or more vigorously active for a longer period like 45 minutes or more is likely to reduce your risk of breast and colon cancer even more.
