Smokers look older than their nonsmoking counterparts and are at greater risk of bladder cancer. Research published in The Lancet's March 24 issue found smokers to have higher levels of a skin protein that causes collagen, which keeps skin firm and elastic, to degrade. In the April 4 issue of the Journal of the National Cancer Institute, a study found that smokers have a two and a half times greater risk of bladder cancer than nonsmokers, and the risks for women are higher than for men at most levels.
