Obesity to be biggest cancer risk for women

Obesity could overtake smoking as the biggest preventable cause of cancer in women 25 years from now, a new report suggests.

More must be done to raise awareness of the “huge public health threat” posed by obesity, Cancer Research UK said.

If current trends continue obesity-related cancers in women could account for 23,000 cases by 2035 – just 2,000 shy of the number which researchers said would be caused by smoking by that year.

By 2043 excess weight could cause more cancers in women in the UK than smoking, the charity’s report concluded.

Authors acknowledged projections of cancer incidence beyond 2035 are less precise but said it could happen if current trends, showing the smoking obesity gap narrowing, continue.

Any such takeover in male cancers is likely to happen much later, the report found, as smoking is currently estimated to cause almost twice as many cancers in men than excess weight.

The charity, which used a formula combining projections of cancer incidence, smoking prevalence and overweight and obesity prevalence, is now launching a Uk-wide campaign to increase awareness that obesity is a cause of the disease.
