A recent international study, lead by the University of Bergen in Norway, found that being overweight (BMI over 25) or obese (BMI over 30) before the age of 40 can increase the risk of different types of cancer.
The study showed that if you were overweight before age 40, the risk of developing cancer increases by:
- 70 percent for endometrial cancer
- 58 percent for male renal cell cancer
- 29 percent for male colon cancer
- 15 percent for all obesity-related cancers (both sexes).
“Obesity is an established risk factor for several cancers. In this study, we have focused on the degree, timing and duration of overweight and obesity in relation to cancer risk,” says Professor Tone Bjørge, at Department of Global Public Health and Primary Care, University of Bergen.
