Which lung cancer is typically peripheral rather than central?

• A. Small Cell Lung Cancer
• B. Squamous Cell Carcinoma
• C. Bronchial Carcinoid Lung Cancer
• D. Adenocarcinoma

Answer: (C)

Adenocarcinoma is typically found in the peripheral regions of the lungs, which distinguishes it from other types of lung cancer that are more commonly central in location. The majority of adenocarcinomas originate in the glandular tissues of the lung, which are located in the outer areas. This subtype often arises in the bronchioles and alveoli, leading to peripheral growth patterns that can manifest as solitary nodules or masses. In contrast, small cell lung cancer and squamous cell carcinoma are generally associated with central lung locations due to their origins in the larger airways and their tendency to form obstructive lesions. Bronchial carcinoid tumor typically arises in the central airways as well, contributing to central growth patterns. Thus, adenocarcinoma is notably recognized for its peripheral occurrence, making it the correct choice in relation to the question.
