Does a widening waistline put you at risk for cancer? Apparently so. According to a new study
Lancet study link
, nearly 6 percent of cancers are attributable at least in part to obesity and diabetes.

Researchers compared incidence data for 12 cancers in 175 countries in 2012 with body mass index and diabetes prevalence figures from 2002, on the assumption that it takes at least ten years for cancer to develop.

They found that in 2012, diabetes and a B.M.I. above 25 were independent risk factors for 792,600 new cases of cancer, about 5.6 percent of the 14,067,894 cases reported to a worldwide cancer registry.

Among the cancers associated with diabetes and high B.M.I. were tumors of the colon, gallbladder, liver and pancreas. Obesity and diabetes weren’t the only causes of these cancers, but the conditions played a role.

“We know a lot about what causes obesity and diabetes, but what it is about being obese or diabetic that causes cancer is less clear,” said the lead author, Jonathan Pearson-Stuttard, a clinical fellow at Imperial College London. “It may be that exposure to high insulin levels or insulin resistance may also be a cause of cancer.”

The study, in The Lancet Diabetes and Endocrinology, found considerable differences in the proportions of cancer cases attributable to B.M.I. on the one hand and to diabetes on the other.

For example, high B.M.I. was associated with about twice as many cases of colorectal cancer as diabetes, and nearly three times as many cases of breast and endometrial cancers. Diabetes was not associated with kidney cancer at all, but high B.M.I. was linked to about a fifth of kidney cancer cases.

High B.M.I. and diabetes combined accounted for 38.4 percent of endometrial cancers but only 8.9 percent of breast cancers. In men, the two conditions combined accounted for 23.3 percent of liver cancers but just 8.6 percent of colorectal cancers.

There were variations by region as well. About 16 percent of cancer cases were attributable to high B.M.I. in high-income Western countries. But only about 5 percent of cancer cases in the high-income Asia-Pacific region were linked to B.M.I.

Diabetes and obesity are increasing worldwide, and the researchers project that cancers, particularly those of the gallbladder, liver and endometrium, will rise as well.

Unless diabetes and obesity are much better controlled, the growth in cancers will be significant. “By 2035, because of increases in obesity and diabetes, there could be a 20 percent increase in men’s cancer and a 30 percent increase for women,” Dr. Pearson-Stuttard said.

How about this: ‘…all cancers are attributable to a constant high glucose level (eating sugar and highly refined and processed carbohydrates) in blood stream and low glucose (combined with anti-oxidant/anti-carcinogens) helps with tolerance and resistance to environmental toxins that cause cancer…’

it is what many have been saying and on twitter some other Doctors calling them quacks etc.

However the science is clear that carbs fuel cancer growth, no one questions that. Of course BMI is false measure but what we need to progress this theory is a full proper double blinded random control study comparing Keto/LCHF people against SAD diet people for rates of cancer …

However as we know that companies seem reluctant to fund this expensive way of checking things, wonder why @Richard hmmmm

That seems like an inconsistent result

SUGAR ZOMBIE APOCALYPSE

(pretty much sums it up)

Umbrella Corp. (sugar industry) hides all the negative research so you don’t have to read it!
