Obesity to be 'main cancer risk in women'
Obesity is set to overtake smoking as the biggest preventable cause of cancer in UK women by 2043, a Cancer Research UK report predicts. Currently, 12% of cancers in women are linked to smoking, and 7% to being overweight and obese. But with the number of smokers falling and obesity rates projected to rise, the charity estimates that gap will disappear in 25 years time. The figures assume that current trends will continue.
