Bladder cancer cannot be prevented, but you may be able to reduce some of your risk for getting it. 1  Stop smoking. Cigarette smokers are much more likely to get bladder cancer than nonsmokers. 2  Avoid exposure to industrial chemicals, such as benzene substances and arylamines.
A crude incidence, prevalence, or mortality (death rate) is one that relates to results for a population taken as a whole, without subdivision or refinement. The crude mortality from lung cancer in men in England and Wales during 1985-89 was 1034/million/year compared with 575/million/year during 1950-54.
Prevalence. The number of people in a population who developed a disease at a specified time, regardless of when it first appeared. This takes into account both old and new cases. It serves as an indicator of how seriously and how long a disease affects a population.
