The World Health Organization's International Agency for Research on Cancer (IARC) has found growing evidence that losing weight may prevent obesity-related cancers. Those include postmenopausal breast, colorectal and esophageal cancers. The American Institute of Cancer Research estimates that if every American were at a healthy weight, 130,000 or more cases of cancer could be prevented.
PositiveTip: Intentional weight loss, when needed, can help lower cancer risk.
