In a recent analysis of data from more than a dozen studies, coffee and tea consumption was linked with lower risks of developing head and neck cancer, including cancers of the mouth and throat. The findings are published by Wiley online in CANCER , a peer-reviewed journal of the American Cancer Society. Head and neck cancer is the seventh most common cancer worldwide, and rates are rising in low- and middle-income countries.
Many studies have assessed whether drinking coffee or tea is associated with head and neck cancer, with inconsistent results. To provide additional insight, investigators examined data from 14 studies by different scientists associated with the International Head and Neck Cancer Epidemiology consortium, a collaboration of research groups around the globe. Study participants completed questionnaires about their prior consumption of caffeinated coffee, decaffeinated coffee, and tea in cups per day/week/month/year.
When investigators pooled information on 9,548 patients with head and neck cancer and 15,783 controls without cancer, they found that compared with non-coffee-drinkers, individuals who drank more than 4 cups of caffeinated coffee daily had 17% lower odds of having head and neck cancer overall, 30% lower odds of having cancer of the oral cavity, and 22% lower odds of having throat cancer. Drinking 3–4 cups of caffeinated coffee was linked with a 41% lower risk of having hypopharyngeal cancer (a type of cancer at the bottom of the throat). Drinki.
