الإجابة: A. Adenocarcinoma
A peripheral irregular lung mass in a non-smoking woman with haemoptysis and weight loss is most likely adenocarcinoma, the most common lung cancer in non-smokers and the one least linked to smoking; it is typically peripheral. Squamous cell carcinoma is strongly smoking-related and typically central. Sarcoidosis would show hilar nodes, and TB/PE do not fit a solitary irregular mass with this history.
