Coffee drinking, mortality, and cancer incidence: results from a Norwegian prospective study.
Relationships between coffee consumption and occurrence of cancer as well as mortality were explored in a Norwegian study of 13,664 men and 2,891 women who in 1967-69 reported their coffee consumption. No statistically significant positive associations were found between coffee consumption and disease. ⋯ For cancer of the pancreas and bladder, no increase in incidence was found among those with a high coffee consumption. In subjects less than 65 years of age at start of follow-up, coffee drinking showed a significant inverse association with colon cancer.
