The solitary pulmonary lesion

Pulmonary cancer when localized to the lung, is curable by operation. Tumors found by routine x-ray examination before they cause symptoms are much more often confined to the lung and as such are curable. Unlike other internal growths which are more hidden, lung tumors can often be seen early on x-ray films of the chest.X-ray films of the chest were made routinely on all patients entering a hospital, regardless of the nature of their illness. In all, some 40,000 films were made. Sixty patients were found to have unsuspected solitary lesions in the lung. Twenty-four of the lesions were diagnosed and treated by operation and removal. Twelve were diagnosed by other methods. Of the 36, eight were cancer of the lung, an incidence of 22 per cent. There were also 14 localized tuberculous nodules which are best treated by removal. Since early cancer is surgically curable, it is felt that everyone over the age of 40 should have a routine x-ray examination of the chest every six months. Solitary lesions of the lung found should be excised for diagnosis.
