People have been drinking tea for many centuries. It is one of the world’s most widely-consumed hot drinks.
Coffee is one of the world’s most popular drinks -- perhaps the most popular. Results of a large American study may help to make it even more popular. The study showed that drinking coffee might help reduce the risk of oral or pharyngeal cancer, a deadly form of cancer.
Researchers questioned 970,000 American men and women who took part in the 30-year-long Cancer Prevention Study. One of the questions was about their use of coffee.
The researchers were with the American Cancer Society. They found that people who drank about four cups of coffee a day reduced their risk of oral/pharyngeal cancer by 49 percent compared to those who had little or no coffee.
Oral cancer and cancer of the pharynx, or upper part of the throat, are aggressive forms of cancer. And they are difficult to treat. Oral and pharyngeal cancers are rare in the United States. But they are among the top 10 forms of cancer worldwide.
Janet Hildebrand is an epidemiologist and population expert with the American Cancer Society. She led the study. She says the less coffee someone drank, the higher their risk of cancer. And the more coffee someone drank, the lower their risk of cancer.
“So it went down a little bit with each cup. And the lowest risk found was found for…four, five, six cups per day.”
