Total cancer risk: Data about total cancer risk was provided by one cohort. No association was found with tomatoes or tomato juice.
Total cancer mortality: Data about total cancer risk was provided by 2 cohorts. A protective effect was found in one cohort of very small size (1), but not in the
larger one (21).
Conclusion: No evidence was found for an association between tomatoes and total cancer.
