Slow weight gain ‘increases cancer risk’

"Men whose Body Mass Index (BMI) rose from around 22 to 27 had a 50 per cent increased risk of developing obesity-related cancer compared with men who stayed within a healthy weight range.
Women who went from a BMI of 23 to around 32 experienced a 17 per cent increase in risk. BMI is a measurement that relates height and weight.

Being overweight or obese is linked to a wide range of cancers – including bowel, breast and pancreatic cancer.

Several obesity-related cancers, such as womb and ovarian cancer, only affect women."
