  1. Study: Association of changes in obesity and abdominal obesity status with early-onset colorectal cancer risk: a nationwide population-based cohort study

    People who stayed overweight or obese over two check-ups were 9% more likely to get colon cancer before age 50 than those who stayed a healthy weight. This study shows that keeping extra weight over time raises your risk.
