Indication: Bladder cancer

Research: Findings from epidemiologic studies of the effect of dairy foods (mainly milk) on the risk of bladder cancer have been inconsistent, so re­searchers examined the association between the intake of cultured milk and other dairy foods and the incidence of bladder cancer in a prospective, population-based cohort. They prospectively followed 82,002 Swedish women and men who were cancer-free and completed a 96-item food-frequency questionnaire in 1997. Incident cases of bladder cancer were identified in the Swedish cancer registries.

Results: During a mean follow-up of 9.4 years, 485 participants (76 women and 409 men) were diagnosed with bladder cancer. Total dairy intake was not significantly associated with risk of bladder cancer. However, a statistically significant inverse association was observed for the intake of cultured milk (sour milk and yogurt). The intake of milk or cheese was not associated with bladder cancer risk. Ac­cording to researchers, these findings suggest that a high intake of cultured milk may lower the risk of developing bladder cancer.
