Repeated pleas for early detection of bronchogenic carcinoma have been published. Periodic thoracic roentgenograms, and particularly the mass surveys designed principally to find tuberculosis, have played important roles in answering these pleas; however, the entire array of diagnostic aids that is available today often does not provide the accurate diagnosis necessary for effective treatment of pulmonary diseases.
