What is the most common form of bronchogenic carcinoma?

Adenocarcinoma is identified as the most common form of bronchogenic carcinoma, particularly in the context of lung cancer overall. This classification of lung cancer is characterized by the presence of glandular cells that produce mucus and can be found in the outer regions of the lungs.

Adenocarcinoma has gained prevalence in recent years, largely attributed to the rise of lung cancer in non-smokers and changes in smoking patterns. It typically arises in the peripheral areas of the lungs and is associated with various risk factors, including exposure to certain environmental toxins, as well as mutations linked to genetic predispositions.

Other types of bronchogenic carcinoma, while significant, do not outpace adenocarcinoma in terms of prevalence. For example, squamous cell carcinoma, though common especially among smokers, represents a smaller percentage of lung cancer cases overall. Large cell carcinoma and lung neuroendocrine tumors are less common in comparison. This statistical predominance makes adenocarcinoma the leading type of bronchogenic carcinoma in clinical practice and research. Understanding its characteristics helps guide screening, diagnosis, and treatment approaches for lung cancer.
