Women More at Risk From Smoke

Cigarette smoke may be more harmful to women than men when it comes to bladder cancer, according to a study by the University of Southern California.
The researchers found that when women and men smoke at comparably high levels, women's bladder-cancer risk is 30 percent to 50 percent higher.
Smoke contributes to bladder cancer because carcinogens in cigarette smoke are absorbed from the lungs into the bloodstream, said Viviana Simon, director of scientific programs for the Society for Women's Health Research, a non-profit organization. The carcinogens are then filtered by the kidneys, concentrated in the urine, and can then damage the cells that line the bladder.
The U.S. incidence of bladder cancer has been steadily increasing, says the American Urological Association. Cigarettes top the list of risk factors. Other risk factors are: increasing age, occupational exposures to chemicals found in some dyes, paints, solvents, leather dust, inks, combustion products, rubbers and textiles.
Relatives and people who spend time with a smoker are also at risk, given the established dangers of secondhand smoke, according to the researchers.
