Melons/cantaloupe and prostate cancer.

Prostate cancer risk: Data about the relation with prostate cancer risk was provided by 4 cohorts. No associations were found, except for a protective association of watermelons among white men in one cohort (17).
Prostate cancer mortality: No data was found.

Conclusion: No evidence was found for an association between melons/cantaloupes and prostate cancer.
