b) It is the most prevalent carcinoma of the lungs in both sexes and in nonsmokers, representing 35-40% of all tumors
c) It is more common in men than in women and occurs almost entirely in cigarette smokers
d) It is aggressive, with rapid growth and early local and distant metastases via the lymphatic and blood vessels.

Answer 1

Adenocarcinoma of the lung is the most common type of lung cancer, accounting for 35-40% of all lung tumors and occurs in both sexes and nonsmokers.

Step-by-step explanation:

The accurate statement about adenocarcinoma of the lung is that it is the most prevalent carcinoma in the lungs, representing 35-40% of all tumors. Adenocarcinoma is the most common type of lung cancer in both sexes, and it is particularly prevalent among nonsmokers, although smoking remains the major risk factor for developing any form of lung cancer. This type of cancer tends to have a more peripheral location in the lung tissues and can be associated with areas of scarring or fibrosis. Adenocarcinoma may indeed be aggressive with the potential for local and distant metastases.
