Adenocarcinoma of the lung tends to be located where?

Adenocarcinoma tends to arise from glandular cells in the distal airways and alveoli, so it commonly forms a lesion toward the outer edges of the lung. This peripheral location makes tumors look like peripheral nodules or masses near the pleura on imaging. Central tumors that rise in the hilum and grow into the major airways are more typical of squamous cell and small cell carcinomas, whereas adenocarcinoma is characteristic for being peripheral.
