The bariatric surgery, used in the treatment of morbid obesity, reduced by 42 percent the likelihood that an overweight woman suffering from cancer, according to a study released today by the British journal The Lancet.
Obesity has always been considered a risk factor for development of some types of tumors, but never so far had shown that surgical intervention to combat overweight could stop this disease.
According to recent estimates, 20 percent of women and 14 percent of men who die of cancer sufferers obesity. A team from Sahlgrenska University Hospital in Gothenburg (Sweden) led by Professor Lars Sjöström has now shown that bariatric surgery reduces by almost half the risk that the collective female suffering from cancer.
Bariatric surgery involves reducing the capacity of the stomach through various techniques, such as gastroplasty, the gastric bypass or adjustable banda. Experts believe that this beneficial effect is due to the hormonal revolution that the reduction of body mass has on women.
In reaching this conclusion, the researchers studied for almost 11 years to 2010 obese patients who had previously undergone a surgical operation, both men and women, who compared with 2037 individuals who received an alternative treatment or who were not treated. Throughout this period, women who had undergone surgery lost an average of 19.9 kilograms, 1.3 kilograms compared to the members who came down the other group.
This difference in weight loss also affected the level of cancer incidence in both groups: while the “operations” were detected 79 cases of cancer in the “non operated” there were 130. However, despite this clear difference among women, researchers found that there were no significant differences between men who had been operated on and those who do not.
