Data that the study prepared by a large team of specialists from the United Kingdom, France and Greece are compelling: 11 types of cancer (of the 36 that were part of this investigation) may be closely related to obesity. Under the title fat and cancer in the main anatomical sites: general review of the literature, this work, published in the British journal BMJ, encompasses a total of 204 research conclusions.
As BMI increases by 5 kg/m2 also increases the risk of developing a malignant tumor for men
According to this meta-analysis, an increase in mass index body (BMI), weight gain, and the ratio of waist to hip circumference has been established as risk factors for the development of the following types of cancer: Esophageal adenocarcinoma, multiple myeloma, stomach, colon, rectum, system of bile ducts, pancreas, breast, endometrium, ovary and kidney.
The study, led by researcher Maria Kyrgiou, shows that significant differences in the incidence of 8 of 11 cancers according to the sex of the patient there are no. Without, however, colon cancer and straight it was higher in men and, on the other hand, the body mass index was associated with an increased risk of melanoma in men. It has also shown that own women’s cancers (breast, endometrium, ovaries…) have a high hormonal component in its emergence.
One of the conclusions reached by this group of researchers is that, as BMI increases by 5 kg/m2 it also increases the risk of developing a malignant tumor in the case of men (9% for rectal cancer or 56% for cancer of the bile system). The risk of breast cancer postmenopausal women who have never used hormone therapy reached 11% for every 5 kg of weight gain in adulthood, while the risk of endometrial cancer rises as the waist circumference increases.
Obesity, second leading modifiable cause of cancer
For the authors of this research, obesity and overweight have become a growing problem of public health. The importance of this study lies in that with the doors open to the preventive measures. Learn more about the relationship between obesity and cancer helps detect patients at high risk of suffering from tumors and make timely prevention in a personalized way.
Recently, in an editorial in the BMJ, the professors Yikyung Parky and Graham A. Colditz also concluded that excess body fat could cause more than 10 types of cancer, which would place the obesity as the second modifiable cause of cancer after smoking.
According to data from 2016 of the Spanish society of the heart, 21.6% of Spaniards are obese, if they are joined by overweight people we are talking about nearly 40% of the population. And if we take the view beyond, concern and figures soar: according to the World Health Organization (who), by 2014 more than 1,900 million adults were overweight, and of these, more than 600 million were obese.
With these data, who proposes to engage in physical activity on a regular basis, maintain a healthy body weight, and a diet healthy as measures necessary to tackle this epidemic. Since this Organization policies and programs claim to inform the population to adopt healthy lifestyle habits. Priority is that such measures be taken since childhood, since the prevalence of obesity in children is reaching alarming figures: in 2010, there were 42 million children overweight worldwide, of which about 35 million live in developing countries. 80% of these children will continue to suffer from obesity in adults with all the consequences that entails: early development of diabetes or cardiovascular disease and, as mentioned already in this article, cancer.
