A study reported in the Journal of the National Cancer Institute found that people who drank coffee daily or nearly every day had half the liver cancer risk than those who never drank coffees. Researchers led by Monami Inoue of the National Cancer Center in Tokyo analyzed a 10-year public health study to determine coffee use by Japanese people diagnosed with liver cancer and people who did not have cancer.
Findings of the study showed the likely occurence of liver cancer in people who never or almost never drank coffee was 547.2 cases per 100,000 people over 10 years. For people who drank coffee daily, the risk was 214.6 cases per 100,000. The researchers found that the protective effect occured in people who drank one to two cups of coffee a day and increased at three to four cups. They were unable to compare the effect of regular and decaffeinated coffee because decaf is rarely consumed in Japan.
While the study shows a statistically significant relationships between drinking coffee and having less liver cancer, the researchers noted that it needs to be repeated in other groups.
