Obesity increases cancer risk than smoking- Research


Obesity now causes more cases of four common cancers in the UK than smoking, according to a a research.

Cancer Research UK says bowel, kidney, ovarian and liver cancers are more likely to have been caused by being overweight than by smoking tobacco.


It says millions are at risk of cancer because of their weight and that obese people outnumber smokers two to one.


Research UK says it is not about blaming people for being overweight.

Nor is it suggesting that smoking and obesity are directly comparable in terms of cancer risk. Both increase a person’s risk.

But it says being overweight or obese causes around 22,800 cases of cancer each year, compared to smoking which causes 54,300. For the four highlighted cancers.


Obesity remains the UK’s leading preventable cause of cancer overall. Obesity ranks second, says CRUK.

But while smoking rates are decreasing, obesity is increasing, which health experts agree is concerning.
