Bronchioloalveolar carcinoma (BAC) is a rare type of lung cancer. It occurs more frequently among never-smokers, women and Asians.[cite journal | last =Raz | first =DJ | authorlink = | coauthors =He B, Rosell R, Jablons DM | title =Bronchioloalveolar carcinoma: a review | journal =Clinical Lung Cancer | volume =7 | issue =5 | pages =313–322 | publisher =Cancer Information Group | date =Mar 2006 | url =http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=16640802&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVAbstractPlus | doi = | id = | accessdate = ] ]By definition, BAC is not an invasive tumor. Therefore, pathologists classify it as a form of carcinoma in situ (CIS). However, unlike other forms of CIS, its behavior is malignant, often lethal. Major surgery, either a lobectomy or a pneumonectomy, is needed to control it, and recurrences are frequent. For this reason, oncologists classify it among the other malignant tumors, which are invasive tumors.
Classification
Bronchioloalveolar carcinoma is a sub-type of lung adenocarcinoma. However it is distinct from other lung adenocarcinomas by different clinical features, prognosis and response to treatment.
