Hot tea could cause cancer says study

A study designed to offer an insight into the complex causes of cancer and possible cancer treatments has revealed that tea drinkers should let their afternoon cuppa cool before taking that first sip.

The research, published in the British Medical Journal and carried out by scientists in Iran, found that drinking black tea at temperatures of 70 degrees C or higher increased the risk of developing oesophageal cancer.

Professor Reza Malekzadeh, who led the research, was among a team of scientists from the University of Tehran who studied the tea-drinking habits of 300 people from Golestan Province in northern Iran who had been diagnosed with cancer of the oesophagus.

The results were then compared with the tea etiquette of 570 people who did not have a throat tumour.

Golestan Province has one of the highest incidences of oesophageal cancer in the world despite rates of alcohol consumption and smoking being very low.

However, tea drinking is widespread and the study found that some of those who took part in the study drank around a litre of black tea a day.

The world's tallest brick tower can be found in Gonbad-e Qabus in the Golestan Province.
