People who drink beer and spirits every day face a much higher chance of developing cancer – and the risk could be seven times greater for some cancers.
People who drink beer or spirits moderately – which is less than every day – or who drink only wine, do not run the same risks.
Researchers say they were shocked by the findings, which show a direct link between heavy drinking and an increased risk for esophageal, stomach, colon, liver, pancreatic, lung and prostate cancers. The greatest risk was for esophageal cancer, with a sevenfold increase, but heavy drinkers also face an 80 per cent increased risk for colon cancer, and 50 per cent for lung cancer.
