Excessive body weight increases the risk of many diseases, including cancer of the pancreas, breast, colon, esophagus, kidney, uterus and bladder.

The study, the experts came to the conclusion that from 123 thousand cases of cancer, 18% (or 22 thousand cases) could have been prevented.

Experts of the World cancer Foundation has compiled all of the latest research on cancer. Scientists came to the conclusion that, for example, 1 257 cases of cancer of the pancreas could not be, if patients are more attentive to their weight.

Professor at Southampton University, Alan Jackson said that "a Significant number of people would not get sick, if maintained a normal weight of his body".

In a new report focuses on the pancreas is the fifth in a degree of mortality, leaving patients a very small chance of survival.

"The first year after the diagnosis, is not experiencing more than one patient out of five. But we found that 15 percent of new cases of diseases can be avoided if to take measures for the maintenance of normal body weight".

Especially big problems with excess weight are observed in women, a figure which increasingly takes the form of Yabloko. The study involving 54 thousand people found that waist circumference, at 5 see exceeding 80 "healthy" centimetres means hit the risk of cancer.

Specialists of the nonprofit organization Nuffield Health claim that "the deposition of fat in the abdominal area, which is measured by waist circumference, is even more accurate indicator of obesity than the body mass index".

However, according to the results of several independent from each other studies, some people with excess weight are in good enough physical shape, and they have not observed predisposition to diseases related to obesity or obesity - diabetes, pressure or cancer.

These "sports" fat men, according to researchers from Spain and Sweden, die from heart disease or cancer by 30 to 50 percent less than the "non-sport".

Dr. Francisco Ortega, who led one of the studies, said: "it has Long been known that overweight increases the risk of cardiovascular disease and cancer. However, some obese people, apparently spared the problems with metabolism that are associated with being overweight".
