Obese women more likely to develop cancer

While obesity is a known risk factor for cancer, researchers at the Cancer Research UK set out to find out which of seven cancers were most likely to affect obese people.

The scientists looked at seven cancers that have been linked to weight--breast, bowel, pancreas, esophageal, uterus, kidney, and gall bladder. They analyzed data on lifetime cancer risk in the U.K., data on overweight and obese women in the U.K.. and the results of a 2011 study that analyzed the link between greater weight and cancer development. The results suggested that obese women are 41 percent more likely to develop one of the seven cancers than women of a healthy weight. They also determined that out of a sample of 1,000 obese women, 274 would be likely to be diagnosed with a weight-related cancer, compared to 194 in a sampling of 1,000 healthy women.

The cancers where the risks were found to be considerably higher for obese women than healthy weight women were esophageal cancer, uterine cancer, gall bladder cancer and kidney cancer.

While there is an increased cancer risk for obese men as well, the link is stronger for women, with 7 percent of cancer cases linked to weight gain for women, compared to 4 percent of cases linked to weight gain for men.
