3. Scale it down
A landmark report by the World Cancer Research Fund found “convincing evidence” that weighing too much is a cause of six different types of cancer, including colon and breast cancer. The review, which included some 7,000 previously-published studies, found that gaining weight can also boost your risk, even if you are within a healthy weight range (BMI 20-25). Other studies have shown being overweight or obese can also impact the likelihood you’ll get screened for various types of cancer.
