These are the real culprits behind 800,000 cases of cancer


According to one study, almost 6% of new cancers diagnosed worldwide in 2012 – around 800,000 cases – were caused by diabetes and excess weight.

Among the 12 cancers examined, the percentage of cases attributed to these factors were as high as one third, researchers reported in The Lancet Diabetes & Endocrinology an important medical journal.

Link between cancer and diabetes

Cancers derived from diabetes and combined obesity were almost twice as common among women as men, they found.

And of the two cancer-causing agents, being overweight or obese – above 25 in body mbad index, or BMI – was responsible for twice as many cancers as diabetes.

Conditions, in fact, are often found together, since obesity is itself a major risk factor for diabetes.

"While obesity has been badociated with cancer for a while, the link between diabetes and cancer has only been established fairly recently," said lead author Jonathan Pearson-Stuttard, a clinical researcher at the School of Medicine. Imperial College of London.

"Our study shows that diabetes, alone or combined with being overweight, is responsible for hundreds of thousands of cancer cases each year worldwide."

An increase in both conditions over the last four decades has worsened significantly, the study showed.

the global increase in diabetes between 1980 and 2002 represented a quarter of the 800,000 cases, while the obesity epidemic during the same period resulted in an additional 30% of cases.

In current trends, the proportion of cancers attributable to both conditions will increase by 30% for women and 20% for men in less than 20 years, the researchers warned.

"In the past, smoking was by far the main risk factor for cancer, but now healthcare professionals should also be aware that patients who have diabetes or are overweight also have an increased risk," Pearson said. -Stuttard.

For men, obesity and diabetes accounted for more than 40% of liver cancers, while for women they accounted for one third of uterine cancers and almost as many cases of bad cancer.

The threshold for obesity is a BMI: the weight in kilograms divided by the height (in centimeters) squared, of 30.

People with a BMI of 25 to 29.9 are considered overweight.
