Cigarette smoking implicated in half of bladder cancers in women; Bladder cancer risk from smoking is higher than previously estimated, study confirms
Current cigarette smokers have a higher risk of bladder cancer than previously reported, and the risk in women is now comparable to that in men, according to a new study. While previous studies showed that only 20 to 30 percent of bladder cancer cases in women were caused by smoking, these new data indicate that smoking is responsible for about half of female bladder cancer cases.
