Daily intake of caffeinated coffee lowers risk of oral cancers
Washington, Dec 11:
People who drink more than four cups of caffeinated coffee per day can halve their risk of mortality from oral cancers, a new study has claimed.
A new American Cancer Society study finds a strong inverse association between caffeinated coffee intake and oral/pharyngeal cancer mortality.
Previous epidemiologic studies have suggested that coffee intake is associated with reduced risk of oral/pharyngeal cancer.
To explore the finding further, researchers examined associations of caffeinated coffee, decaffeinated coffee, and tea intake with fatal oral/pharyngeal cancer in the Cancer Prevention Study II, a prospective US cohort study begun in 1982 by the American Cancer Society.
Among 968,432 men and women who were cancer-free at enrolment, 868 deaths due to oral/pharyngeal cancer occurred during 26 years of follow-up.
Researchers found consuming more than four cups of caffeinated coffee per day was associated with a 49 per cent lower risk of oral/pharyngeal cancer death relative to none or occasional coffee intake.
A dose-related decline in relative risk was observed with each single cup per day consumed. The association was independent of sex, smoking status, or alcohol use...
