Tea Drinking Temperature and Risk of Esophageal Cancer

Multiple observational studies have reported an association between hot beverages and Esophageal cancer. A major limitation of all previous prospective studies is that data have been based on the self-reported perception of tea drinking temperature. The International Agency for Research on Cancer (IARC) has concluded that since there is a limitation with the evidence, they have classified "drinking very hot beverages at above 65C" as "probably carcinogenic" (Group 2A) rather than "carcinogenic" to humans (Group 1).
