Total dairy and total cancer.

Total cancer risk.

5 articles, providing information about 5 different cohorts were found, including 61,695 cases.
Results: A nonsignificant protective effect (trend) was found in 1 cohort (11), and in another cohort among women only (13). No other associations were found.
Effect modification: No data was found.
Conclusion: No significant associations were found. No evidence was found for an association between dairy consumption and total cancer risk (Excluding incomplete data from McCullough ML [5]: Average RR = 1.01).

Total cancer mortality.

3 articles, providing information about 3 different cohorts were found, including 15,300 cases.
Results: No associations were found.
Effect modification: Data about effect modification was provided by one cohort (14). Similar results were found for intakes of low- and full fat dairy products.
Conclusion: No associations were found. No evidence was found for an association between dairy consumption and total cancer mortality (Average RR = 1.00).
