THURSDAY, Feb. 25 (HealthDay News) -- Certain foods are associated with an increased or a decreased risk of bladder cancer, and diet should be a component of care for patients with the disease, according to an article published in the February issue of Urology.

Jonathan L. Silberstein, M.D., and J. Kellogg Parsons, M.D., of the San Diego Medical Center, conducted a review of articles that looked at both diet and bladder cancer to see what foods were associated with risk for the disease. They write that bladder cancer is the most expensive cancer to treat, with 68,000 cases and 14,000 deaths in the United States in 2008, and has a 50 to 90 percent recurrence rate in newly diagnosed patients with organ-confined, superficial disease.

Carrots, selenium, cruciferous vegetables and fruits are all associated with a lower risk of bladder cancer, while foods associated with an increased risk include pork, barbecued meats, fat, soy and heavy coffee consumption, the authors write.

"Although these data are observational and should thus serve primarily as a guide for informing the design of future clinical trials, there is little, if any, downside to promotion of healthy lifestyle interventions based on diet change -- specifically, increasing vegetable and fruit intakes and decreasing meat and fat intakes -- among patients with bladder cancer, particularly as these diet-based interventions possess proven benefits to overall and cardiovascular health," the authors conclude.
