What is bronchoalveolar carcinoma?

Bronchoalveolar carcinoma (BAC) is a sub-category of adenocarcinoma, a type of lung cancer that occurs in the marginal parts of the lungs. Bronchoalveolar carcinoma grows near the lung's air sacs (alveoli) or either of the two windpipes that branch out from the trachea to each lung (bronchi). Lung cancer is usually classified by which type of carcinoma cell invades the lungs. The types of carcinoma can be broken into small cell (appearing smaller than normal cells and attacking more aggressively) and non-small cell. Non-small cell carcinoma includes large cell (appearing bigger than normal cells), squamous cell (usually flat and found lining internal organs), or adenocarcinoma (usually appears similar to a gland), of which bronchoalveolar carcinoma is a sub-type.
