Hot tea can cause cancer in smokers
Tehran (KNA) - If you smoke cigarettes , you may want to consider letting your tea cool before you enjoy it. Drinking tea while it's too hot could increase your risk of esophageal cancer, a new study suggests.
In the study, published Monday in the Annals of Internal Medicine, drinking "hot" or "burning hot" tea was associated with a two- to fivefold increase in esophageal cancer, but only in people who also smoked.
Esophageal cancer is the eighth most common cancer in the world and is often fatal, killing approximately 400,000 people every year, according to the International Agency for Research on Cancer. It is usually caused by repeated injury to the esophagus due to smoke, alcohol, acid reflux and -- maybe -- hot liquids.
The study, the largest of its kind, followed close to 500,000 adults in China over an average of 9½ years. Because of the large size, it may set the bar for years to come, according to Neal Freedman, senior investigator at the National Cancer Institute in Bethesda, Maryland, who was not involved in the new research.
