An anonymous reader writes from a report via USA Today: The World Health Organization reports that drinking coffee, tea and other beverages at temperatures hotter than 149 degrees Fahrenheit may lead to cancer of the esophagus. These hot beverages can injure cells in the esophagus and lead to the formation of cancer cells, said Mariana Stern, an associate professor of preventative medicine and urology at the University of Southern California's Keck School of Medicine. But scientists did say that if you drink coffee at cooler temperatures, it is not only safe but it may decrease of the risk of liver cancer by 15%, according to research published in Lancet Oncology. Previously, the International Agency for Research on Cancer ruled coffee was a "possible carcinogenic" in 1991. The research involved Stern and 22 other scientists from 10 countries, who examined about 1,000 studies on more than 20 types of cancer.
