Bariatric surgery ‘safeguards against cancer’

5 June 2014

Weight loss surgery could safeguard morbidly obese people against cancer, as well as helping them shed pounds, according to new research published in Springer’s journal Obesity Surgery.

The study suggests bariatric surgery reduces the risk so they almost match those of people at a normal weight.

Cancer rates in obese people can be as high as 2.12 cases per 1,000 person-years, which is the product of the number of years multiplied by the the number of people in a population that have been affected by a certain condition.

As previous studies have suggested a relationship between the disease and weight loss surgery, the research team wanted to examine the claims further.

They conducted a meta-analysis of 13 studies concerning 54,257 participants. The results found an association between bariatric surgery and a reduction in the incidence of cancer among morbidly obese patients.

The findings revealed the disease occurred in 1.06 cases per 1,000 person-years, up to 23 years after the surgery was originally performed. These results are better than the average rate for the global population of obese people.

Daniela Casagrande, of the Universidade Federal do Rio Grande do Sul in Brazil and lead author of the study, said: “Bariatric surgery is associated with reduced cancer risk in morbidly obese people.”
