Recent studies and reports reveal concrete link between excess body fat and deadly cancers
A study originally published in August 2016 revealed that thirteen different cancers are, without a doubt, linked to obesity or being severely overweight. Of these thirteen cancers are some of the deadliest and most common: thyroid, ovarian, pancreatic, breast, and colon.
The C.D.C.P. published a similar report earlier this month, stating that more than half a million Americans categorized as obese or morbidly obese received diagnoses for cancers related to body-fat in 2014 - a staggering 40% of total diagnosed cancers that year.
So far, although many lifestyle habits have been associated with increased cancer diagnoses (such as high alcohol and tobacco consumption), modern science has made little progress in determining which specific foods are dangers.
The studies have established that individuals are heavily overweight after they have already received a cancer diagnosis: but not the scientific link between the excess weight and cancer itself.
It would be almost impossible to carry out a cause and effect study over a course of years: for example, randomly assigning different individuals to different diets and monitoring them for cancer surges.
However, short-term studies observing the eating habits of individuals and later cancer diagnoses generate more confusion than knowledge: one study may reveal meat consumption is linked to cancer, another dispute the former in a matter of months.
Unusually high insulin levels may cause tumor growth
So far, the best explanation for so-called weight-related cancers is explained by high insulin rates, found in both obese patients and cancer patients.
Researchers theorize that too high insulin levels result in the human tissue receiving more “fuel” and growth signals. These signals can also work on cancerous tumors.
Although research on this issue continues, scientists warn that cancer risks may not simply be consuming too much food, but consuming foods that are likely to result in dangerously increased levels of insulin.
