Obesity strongly increases the risk of developing 11 types of cancer, a major study has revealed.
Being overweight is probably linked to many other forms of the illness but so far there is not enough evidence, researchers say.
Types linked to obesity include breast, oesophagus, stomach, bowel, rectum, biliary tract system, pancreas, womb, ovary, kidney and the blood cancer myeloma.

Researchers from Imperial College London calculated that men’s risk of developing biliary tract cancer increases by up to 56 per cent for every 11lb gained in weight.
For women, the risk of womb cancer rises by 21 per cent for every 0.1 point increase in hip to waist ratio.
The findings are particularly concerning as a quarter of adults and a fifth of 11-year-olds are classed as obese.
