Which is false about adenocarcinoma of the lung?
NSCLC is divided fuher into adenocarcinoma, squamous cell carcinoma (SCC), and large cell carcinoma histologies. Adenocarcinoma, arising from the bronchial mucosal glands, is the most frequent non-small cell lung cancer, representing 35-40% of all lung cancers. It usually occurs in a peripheral location within the lung. Adenocarcinoma is the most common histologic subtype, and may manifest as a "scar carcinoma". This is the subtype observed most commonly in persons who do not smoke. This type may manifest as multifocal tumors in a bronchoalveolar form.
