Following a diet that encouraged the consumption of foods high in flavonols and lignans may decrease bladder cancer risk. 

This research work studied the link between high dietary exposure to flavonoids and lignans and the propensity to develop bladder cancer. Researchers collated and analyzed data on the dietary preferences and bladder cancer rates of more than 470,000 men and women within the age bracket of 35-70 years recruited from 10 European countries.

Researchers observed that habitual consumption of foods loaded with lignans and flavonols brightened an individual's chances of avoiding a diagnosis of bladder cancer, especially the aggressive form of urothelial carcinoma. This study points out that diets rich in flavonols and lignans may confer an individual with adequate protection against bladder cancer.
