Low levels of alcohol intake have been found to decrease risk of esophageal cancer.
The exact cause of esophageal cancer is not known. Previous research has stated it is more common in people with acid-reflux, and people with acid-reflux tend to be obese.
This particular research was based on 17 studies with information regarding giving up alcohol and risks of esophageal cancer. The authors discovered that alcohol-related risk of esophageal cancer is changeable after stopping alcohol intake, taking 16 years to return to non-drinking risk levels. They believe one half of the decrease in risk of cancer could occur within 4 to 5 years.
The important conclusion is that quitting drinking may decrease risk of esophageal cancer. Other studies suggest just reducing alcohol intake to a moderate level can be associated with lowering of cancer risk for non-smokers. Low level alcohol consumption has also been seen to have advantageous effects on diabetes, cardiovascular disease, and other medical conditions.
