00:00Having obesity in your 20s and 30s may raise the risk of cancer within a decade.
00:05Researchers led by a South Korean doctor followed more than 6 million adults aged 20 to 39.
00:11All were healthy at the start, and they were tracked for about 10 years.
00:15Among people at a normal weight, 1.8% developed cancer.
00:19With obesity, that rose to 2.2%.
00:21With more severe obesity, it reached 2.6%.
00:25People with excess belly fat had the highest cancer rates overall.
00:29Thyroid, endometrial, and ovarian cancers showed some of the strongest links.
00:34Researchers did not find a significant link with breast cancer.
00:37The study, published in the Annals of Internal Medicine, cannot prove cause and effect.
00:42The authors note limits, including a lack of detailed smoking data.
00:46They say more research is needed to learn whether intentional weight loss lowers the risk.
