Researchers have been studying a lot of time to determine if there is a link between coffee and cancer consumption, but have had problems in extracting results from other cancer-causing habits, such as smoking.
A new study, presented to the American Cancer Research Association (AACR), sees coffee and tea consumption in smokers and non smokers and has found that a link may exist between liquor and the risk of lung cancer. The study is still ongoing and the results are not yet finalized, but based on preliminary findings, researchers believe there may be an increased risk of lung cancer in people who drink at least two cups of coffee each day.
Researchers conducted a meta-analysis at over 1.2 million people using data from previous US and Asian population studies. They praised the participants' information including coffee and tea drinking, demographics and lifestyle factors as smoking in each of the 17 studies. "These populations have different patterns of consumption and genetic make-up. Such a study would be more informative than a single population study," said INSIDER, Dr. Xiao Ou Shu, the lead author of the study.
To better understand whether smoking has affected results, researchers have seen people who have never smoked and actually smoke. So far, researchers have found that people who reported drinking two or more cups of coffee or tea a day had an increased risk of lung cancer.
This was true for both smokers and non-smokers, suggesting that beverages could be the risk factor for cancer. The coffee temperature is also studied as a potential risk factor for cancer. In two studies, researchers found that people who drank hot drinks had slightly higher risks of developing esophagus or throat cancer.
However, since existing coffee and cancer research is largely unconventional, do not leave aside your cup of coffee in the morning because this is not an unmistakable way to reduce the risk of cancer.
