Drinking very hot tea linked to cancer risk
Iranian scientists have discovered that drinking steaming hot tea may increase the risk of oesophageal, or food tube, cancer. They found that drinking black tea at temperatures of 70C (158F) or higher increased the risk of cancer in the muscular tube that carries food from the throat to the stomach. Compared with drinking warm or lukewarm tea (65C or less), drinking very hot tea (70C or more) was associated with an eight-fold increased risk. Oesophagus cancers kill more than 500,000 people worldwide each year and oesophageal squamous cell carcinoma (OSCC) is the most common type of the disease.
