The latest weapon in the war against cancer could be water. Boston doctors have found that a high fluid intake can help prevent bladder cancer in men.
Men are four times more likely to develop bladder cancer than women.
For each cup of liquid consumed a day, you cut your cancer risk by about 7 percent. The men in the Boston study who drank more than 10 cups of liquid a day had about half the cancer risk of men who drank less than five cups a day. It's not just water that has this effect. Any fluid appears to work, even caffeinated liquids such as coffee or tea. That could be because drinking a lot makes fluid move more quickly through the bladder, which means bladder tissue is exposed to potentially harmful substances for a shorter amount of time.
