[Bronchial carcinoma. Epidemiology, diagnosis and therapy].

Bronchial carcinoma still has a dark prognosis and therapeutic progress remains painfully slow: the 5-year survival rate raised in the last 20 years from 11 to 15%. There are no early symptoms by the tumor and detection by screening is not effective. Worldwide incidence is raising, the falling rates in men in the western world have been compensated by a steep increase in eastern Europe an Asia.
