New Study Reveals Drinking Very Hot Beverages could Cause Oesophageal Cancer
A new research warns, sipping an extremely hot cup of tea or coffee can double the risk of oesophageal cancer or the cancer of the food pipe.
Scientists say drinking piping hot water damages the lining of the mouth and throat, which can further cause tumours. A study involving more than 50,000 people revealed those who regularly drank hot beverages at 75 C (167F) are at a risk of 2.4 times more than those who drink at 60 C (140 F).
Lead author Dr Farhad Islami, from the American Cancer Society, said: “Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking very hot tea can increase the risk of oesophageal cancer, and it is therefore advisable to wait until hot beverages cool down before drinking.”
The study, which has been published in the International Journal of Cancer, looked at the drinking habits of people residing in north-eastern Iran and in between the age group of 40 to 75. The study applies to other hot beverages as well, including hot chocolate.
In between 2004 to 2017, 317 cases of oesophageal cancer emerged. It is more common in men than women and affects people in their 60s or 70s.
Difficulties in swallowing, heartburn or indigestion, loss of appetite, weight loss, pain in upper area of stomach, chest or back, are common symptoms of oesophageal cancer.
Georgina Hill, health information officer at Cancer Research UK, said: “This study adds to the evidence that having drinks hotter than 60 degrees may increase the risk of oesophageal cancer, but most people in the UK don’t drink their tea at such high temperatures.
“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 – and not smoking, keeping a healthy weight and cutting down on alcohol will do much more to stack the odds in your favour.”
The International Agency for Research on Cancer (IARC) in 2016 said drinking hot beverages above 65 C could cause cancer. When the IARC conducted research, it examined only a particular type of tea, mate, which is traditionally drunk very hot in South America, Asia, and Africa. However, they concluded that it was the temperature that could cause cancer and not the type of drink.
