Can drinking coffee half your risk of mouth cancer?

A study published in the American Journal of Epidemiology examined associations of caffeinated coffee, decaffeinated coffee and tea intake with deaths from oral or pharyngeal cancer. A total of 968,432 US men and women who were free of cancer were analysed in this study with an average age of cohort was 57 years at enrolment (in 1982).
This large prospective cohort study suggests that the risk of death from oral or pharyngeal cancer is approximately 50% lower in men and women who consume more than four cups of caffeinated coffee a day compared with those who drink no or occasional caffeinated coffee. Furthermore, a dose-related decline in relative risk was observed with each single cup per day consumed. This means that for every extra cup per day consumed the risk of death from oral or pharyngeal cancer reduced proportionally. These associations were independent of gender, smoking status or alcohol use (well established risk factors for oral or pharyngeal cancer) and similar effects were not seen for tea intake.
There are several limitations associated with this study worth considering. The study participants were predominantly white, middle aged or elderly and well educated; therefore, results may not be consistent in other groups who may have different cancer risk profiles.
