New research shows an increased risk of large bowel cancer for each 1 cm rise in waist circumference. In addition, in men, there is now evidence that increasing waist circumference in middle age is associated with increased bowel cancer risk.

Experts speaking at the 23rd United European Gastroenterology Week (UEG Week 2015) in Barcelona, Spain revealed compelling evidence of the link between excess body weight and risk of colorectal cancer. John Mathers, Professor of Human Nutrition from the Institute of Cellular Medicine at Newcastle University in the UK presented data showing an overall increase of 18% in relative risk of colorectal cancer per 5 unit increase in body mass index (BMI).

Prof. Mathers noted that in men, there is now evidence that increasing waist circumference in middle age is associated with increased bowel cancer risk. Colorectal cancer risk was increased by nearly 60% in men who gained at least 10 cm in waist circumference over 10 years.

Researchers believe that there is now compelling evidence that improved lifestyle, particularly better dietary choices and being more physically active, can help to prevent obesity and this will lower bowel cancer risk.
