Epidemiology of lung cancer, secondhand smoke

Issue of the passive smoking and its dependence to human health is broadly studied; especially its impact on the genesis of bronchogenic carcinoma. As we can see in the clinical characteristics, diagnostics and follow up therapy, the main troubles of lung cancer generally are diagnostics and surgical treatment of the early stages. Earlier stages of lung cancer are frequently asymptomatic. The potency for radical therapy is worse for the patients in the advanced stages. Lung cancer is still one of the most extended cancer diseases in the world and also in Czech. Incidence of men lung cancer decreases in last years, but is still warningly high. Incidence of women lung cancer is growing up in Czech and in the world. Men and women mortality is still very high Main risk factors for lung cancer are active and also passive smoking. More than 90 percent of the patients with that disease are active smokers. However, the role of passive smoking is broadly explored today. Relationship of the passive smoking and lung cancer is significant. Strength of this relationship is object of many studies today. I try to find relationship between lung cancers and passive smoking by my own study too. I used to questionnaires filled by patients of FNB (The Faculty Hospital Na Bulovce). Odds ratio for passive-smokers/nonsmokers was..
