It's bad news for people who like a nice hot cup of coffee or tea to kick start their day.
A new study has shown that very hot drinks may be linked to a 90% higher risk of oesophageal cancer, a study of 50,000 people suggests.
Published in the International Journal of Cancer, the study looked at the drinking habits of 50,045 people aged 40 to 75 who lived in north-eastern Iran.
During a follow-up period from 2004 to 2017, 317 new cases of oesophageal cancer - also known as cancer of the food pipe - were identified.
As long you're letting your tea cool down a bit before you drink it, or adding cold milk, you're unlikely to be raising your cancer risk
In 2016, the International Agency for Research on Cancer - the cancer agency of the World Health Organisation - classified drinking very hot beverages above 65C as a probable carcinogen.
The researchers behind the new study, including from the University of Cambridge, concluded: "Our results substantially strengthen the existing evidence supporting an association between hot beverage drinking and (oesophageal cancer)."
