Almost half of women in England are at an increased risk of cancer because they have a high waist circumference, a charity has warned.
The World Cancer Research Fund said that 44 per cent of women in the country have large waistlines compared to 32 per cent of men.
It is known that excessive body fat increases the risk of developing cancer.
Large waistlines have also been linked to cancers of the bowel, breast, endometrium and pancreas.
Dr Rachel Thompson, deputy head of science for the organisation, said: "We need to raise awareness among both men and women that both being overweight and having a large waistline are cancer risk factors.
"That is why it is a good idea to measure both your waist and also your body mass index (BMI). If you have a large waist measurement or are in the overweight or obese range, then you can take steps to move towards a healthy weight."
Obesity or being overweight is linked to a number of other medical conditions, including heart disease and hypertension.
