Researchers say that while coffee is not likely to improve the possibility of cancer, consuming very beverages which can be hot improve the danger of esophageal cancer tumors.
Researchers from across 10 countries - including Mariana Stern, associate professor of preventive medication and urology at the University of Southern California - publish their findings in The Lancet Oncology.

The review that is new that drinking very hot beverages may are likely involved, especially after finding no association between consuming cold or hot yerba maté and increased cancer risk.
"We were now able to evaluate more carefully the end result of maté it self from the aftereffect of heat, and now we concluded that the observed links between maté ingesting and cancer of the seem that is esophagus be largely driven by drinking maté very hot. Similar associations are noticed for any other extremely beverages which can be hot like tea or coffee."
