A new study says drinking piping hot tea almost doubles the risk of cancer. Researchers with the American Cancer Society have found that tea drinkers who like their tea warmer than 140 degrees Fahrenheit and consumed about two large cups per day had a 90-percent higher risk of esophageal cancer, compared to those who drank their tea cooler. Previous studies have found a link between hot tea and cancer of the esophagus. The new study published Wednesday is the first to pinpoint a specific temperature. The study's lead author advises tea drinkers to wait until it cools down before drinking.
