It entails discrete proliferation of type II pneumocytes or Clara cells along the alveolar walls and occasionally also the respiratory bronchioles. Adenocarcinoma is usually a slow-growing cancer, but can be difficult to detect because the disease typically involves the periphery of the lung, resulting in fewer early symptoms than cancers that develop centrally, near the airways.
