CNN -- Many people start their day with a cup of tea. But those who drink it pipping hot could be increasing their risk of esophagael cancer according to a new study.

Researchers found that tea drinkers who like their beverages to be warmer than 60 degrees Celsius (140 degrees Fahrenheit) and consumed more than 700ml of tea per day -- about two large cups -- had a 90% higher risk of esophagael cancer, when compared to those who drank less tea and at cooler temperatures.

The study looked at more than 50,000 people in Golestan, a province in northeastern Iran.

"Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking very hot can increase the risk of esophagael cancer, and it is therefore advisable to wait until hot beverage cool down before drinking," said Dr. Farhad Islami, of the American Cancer Society and the study's lead author
