A soda-cancer link?
Shape, Sept, 2004 by Sharon Cohen
Esophageal cancer is usually fatal. Luckily, it's also relatively rare, but rates are steadily rising. Obesity, smoking and excessive alcohol consumption are risk factors, and now some scientists believe they have found another possible link: heavy consumption of carbonated soft drinks. One theory is that sodas make the stomach distend; this in turn leads to gastric reflux, the backing up of stomach acid into the esophagus that causes heartburn and has been linked to esophageal cancer.
At this point, the link remains theoretical. "If future studies confirm that people who drink more soft drinks do have a higher rate of esophageal cancer, it will most likely be because they suffer more from obesity and reflux disease," says gastroenterologist Lee Kaplan, M.D., Ph.D., director of the Obesity Research Center at Massachusetts General Hospital in Boston. Difficulty swallowing is the most common symptom of the cancer.--S.C.
