A cause of the development of a rare cancer identified by scientists

Although the number of pancreatic cancer cases has increased in recent years, American scientists have studied nearly a million cases and concluded that being overweight may increase the risk of developing pancreatic cancer.

A team of US scientists has reassessed the impact of overweight on the risk of developing pancreatic cancer, reports the EurekAlert! Portal.

The researchers studied the size and weight of 963,000 Americans voluntarily enrolled in the CPS II (Cancer Prevention Study II) program. Using these data, the scientists calculated body mass index (BMI) and analyzed how overweight influenced the development of pancreatic cancer.

Throughout the observations between 1982 and 2014, 8,354 participants died of this disease and, as it was assumed, many of them had a high BMI. In addition, at an early age, the risk of developing pancreatic cancer due to overweight problems is greater than among the elderly.

Thus, among people aged 30 to 49 years and with a BMI that exceeds the five-point pattern, this risk increases by 25% in individuals between 50 and 59 years, 19%, between 60 and 69 years. years, falls to 14% and, finally, people between 70 and 89 years old, to 13%.

"Weight gain is a likely reason, but previous studies have shown that overweight has little influence on increased risk [de développement du cancer du pancréas, ndlr] and it is not enough to fully explain the recent increase in the frequency of this cancer, "according to lead researcher Eric J. Jacobs.

Scientists point out that previous data on the influence of overweight should be minimized and believe that the key factor is smoking.

However, after 2000, the number of smokers dropped while that of deaths from pancreatic cancer increased, according to the scientist ahead of this study.
