TUESDAY, Oct. 25 (HealthDay News) -- Men who drink plenty of
low-sugar fluids may reduce their risk for bladder cancer, new
Although the reason for the association between fluid intake and
protection against cancer remains unknown, researchers theorize the
fluids may flush out potential cancer-causing agents before they
have a chance to cause any damage.
In conducting the study, Jiachen Zhou, a doctoral candidate in
epidemiology at Brown University, and colleagues evaluated the
fluid intake of nearly 48,000 men who were part of a long-term
study. The men, who were aged 40 to 75 when they enrolled in the
study in 1986, answered a questionnaire about their fluid intake
every four years for more than two decades.
The investigators found that the men with a high daily fluid
intake, or those who drank more than 10 cups (2,531 milliliters)
per day, had a 24 percent reduced risk for bladder cancer. The
study authors concluded that doctors should tell their patients to
drink plenty of low-sugar fluids.
Although this link between fluid intake and bladder cancer risk
was discovered 10 years ago, the association, the study found, was
stronger among younger men. This could be due to the fact that the
men drank less as they aged, particularly water, the researchers
pointed out in a news release from the American Association for
The study findings -- which revealed an association between
fluid consumption and reduced cancer risk, but not a
cause-and-effect -- were slated for presentation Oct. 24 at the
AACR International Conference on Frontiers in Cancer Prevention
Research, in Boston. Research presented at medical meetings should
be viewed as preliminary until published in a peer-reviewed
