New study finds coffee helps prevent head and neck cancer

The team surveyed the habits of 961 patients with head and neck cancer, esophageal cancer and 2883 healthy people and found that there was no significant difference in the risk of head and neck cancer between those who drank less than one cup of coffee a day and those who drank one cup of coffee a day. However, if you drink more than two cups of coffee a day, the risk of head and neck cancer will be reduced. People who drank more than three cups of coffee a day had a nearly half lower risk of cancer than those who drank less than one cup of coffee a day.

The team also found that people who drank more coffee had a lower risk of head and neck cancer among smokers and drinkers. However, drinking coffee has no preventive effect on esophageal cancer.

"after the substance in the cell is oxidized, DNA (deoxyribonucleic acid) is damaged, which can cause cancer," Oase said. Perhaps because coffee has the effect of antioxidation and oxidation is neutralized, it prevents head and neck cancer. "

According to previous epidemiological investigations, coffee drinkers are also less likely to suffer from colorectal cancer and liver cancer.
