Lungs Non-Smoker Lung Carcinoma!

A 55-year-old female with recent cough and weight loss is found to have an irregular mass in the lower lobe of the left lung. She has never smoked and has no history of exposure to industrial pollutants. Bronchoscopy is scheduled to obtain tissue for histological examination. If a malignant is diagnosed, it is most likely to be which of the following types?

A. squamous cell carcinoma
B. adenocarcinoma
C. bronchioalveolar carcinoma
D. small cell carcinoma
E. large cell carcinoma

I can't tell between adenocarcinoma and bronchioalveolar carcinoma. Anyone could give me a clue? Thanks a lot!

its most likely adenocarcinoma ,,, its the most common tumor in nonsmokers and in females

bronchoalveolar is also in non- smokers but its less common than adenocarcinoma

i agree......and also adenoCA presents as irregular mass....this is unlikely in bronchoalveolar ca( mimic pnemonias and spread along alveolar walls)
