Early menopause related to bladder cancer risk

NEW YORK (Reuters Health) - Women who are relatively young when they go through menopause seem to be at increased risk of developing bladder cancer, researchers from the University of Minnesota School of Public Health in Minneapolis report.
Bladder cancer is quite common in the U.S., representing about 6 percent of all new cancer cases among men and 2 percent among women, Anna E. Prizment and colleagues point out in the International Journal of Cancer. It's well known that smoking and chemical carcinogens increase the risk, and that it goes up with age.
The researchers looked for factors associated with bladder cancer in a study of 37,459 women between the ages of 55 and 69 years from Iowa. The women were initially free from cancer in 1986, and they were followed through 2003.
