Over the years, numerous studies have examined coffee consumption as it relates to cancer risk. This slide show highlights research in glioma, head and neck cancers, hepatocellular carcinoma, prostate cancer, colorectal cancer, breast cancer, melanoma, and endometrial cancer.
A study conducted by researchers in the United Kingdom found that adults who drank five or more cups of coffee or tea a day had a 40% lower risk of being diagnosed with glioma (relative risk = 0.60; 95% CI, 0.41-0.87; P = .04). The researchers examined 335 cases of gliomas from three cohort studies and assessed coffee and tea intake at baseline and during follow-up using food frequency questionnaires. No association was found with decaffeinated coffee or tea.[1]
Researchers investigated whether there was an association between prediagnostic coffee and tea intake and the risk of prostate cancer recurrence/progression. The pattern of coffee and tea consumption was assessed for the 2-year period before diagnosis. Prostate cancerâspecific outcomes were determined using a follow-up survey with a median follow-up of 6.4 years. One hundred and forty prostate cancer recurrences/progression cases were reported. Coffee intake was associated with a reduced risk of prostate cancer recurrence/progression; the adjusted hazard ratio for ⥠4 cups/day vs ⤠1 cup/week was 0.41. No association was found between tea intake and prostate cancer recurrence/progression.[4]
Researchers found that consumption of four or more cups of caffeinated coffee per day was associated with a 20% decreased risk for malignant melanoma, using data from a food frequency questionnaire that was part of the National Institutes of Health-AARP prospective cohort study. No decreased risk for melanoma was linked to decaffeinated coffee.[7]
