                                               EXAM ( EPIDEMIOLOGY SECTION)

A prospective study for lung cancer and cigarettes smoking was done on a cohort of  960 persons,  75% of them  were  not smokers. Lung cancer was found in 192 persons and 144 of them were smokers  . Retrospective  and  a  prevalence studies showed the same results.

A NEW SCREENING TEST FOR LUNG CANCER WAS EVALUATED IN THE SAME COHORT OF 960 PERSONS. THE TEST WAS POSITIVE IN 96 HEALTHY PERSONS AND WAS  NEGATIVE IN 48 PATIENTS.
