Processed meat and total cancer.

Total cancer risk: No data was found.
Total cancer mortality: Data was provided by 4 cohorts, including 30,931 cases. A significantly increased risk was found among both men and women in one cohort of very large size (Sinha R [14]). The average RR = 1.09. This effect size is primarily driven by one single cohort (Sinha R [14]).
Conclusion: A significantly increased cancer mortality risk was found in one cohort of very large size. No other associations were found. Inconclusive evidence was found for an association between processed meat consumption and total cancer mortality. No data was found about the relation with total cancer risk.
