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.
Cancer prevalence is defined as the number of living people who have ever been diagnosed with cancer. It includes people diagnosed with cancer in the past as well those who were recently diagnosed. Cancer prevalence is determined by how often a cancer occurs (incidence) and by how long people normally live after diagnosis (survival). This means prevalence counts are highest for the most common cancers with the longest survival.
