What to do if I'm a smoker. Some time ago I heard that smokers get bladder cancer is bigger to us. Do you know any medic?

Don't understand ? It is not clear what you are asking, and you need to state your question more clearly, or perhaps have someone look it over to help you with it. There is an increase incidence of bladder cancer in smokers, but it is not even in the top 10 of cancers in smokers - lung cancer, cancer of mouth, throat, larynx, esophagus and stomach, and breast cancer are higher on the list. The best preventive - STOP.
