Obesity and Risk of Esophageal Adenocarcinoma and Barrett’s Esophagus: A Mendelian Randomization Study
Data from the Barrett's and Esophageal Adenocarcinoma Genetic Susceptibility Study were used to determine the relationship of a genetic risk score associated with obesity to cancer risk. The risk score was not associated with GERD or smoking. Cancer and Barrett's were strongly associated with increasing BMI. The authors conlude that those with a genetic makeup associated with obesity have increased risk of cancer and Barrett's.
