A new study led by epidemiology graduate student Eddie Jiachen Zhou suggests that men who drink more fluids have a lower risk of bladder cancer, although the effect is stronger in younger men than older men. He presented his research this week in Boston at the 10th International Conference on Frontiers in Cancer Prevention Research. In examining data on more than 47,000 men, Zhou and his co-authors found that high total fluid intake (more than 2.5 liters a day) was associated with a 24-percent reduced risk for bladder cancer. Zhou told the American Association for Cancer Research that a possible reason for the effect is that carcinogens are flushed out of a person’s bladder more quickly if he drinks more.
