Abstract: 164 patients with early cancer of the lungs, i.e., without extrathoracic spread or distant metastasis, were examined. Subjective and objective characteristics of the pain were studied. A correlation was found between the location of the neoplasm, the location of the pain and the characteristics of the sensory changes. These observations may be a useful contribution to the early diagnosis of primary carcinomas of the lungs.
Which is the apt title for the abstract? option1: Pain in early cancer of the lungs. option2: Partitioning of the L4-L5 dynamic moment into disc, ligamentous, and muscular components during lifting.
