<unk>  <unk>  is a rare type of lung cancer which more frequently among never-smokers, women and Asians( particularly Eastern-Asian). In the new WHO classification of lung adenocarcinoma's, changes were made as proposed by the 2011 IASLC/ATS/ERS and bronchioloalveloar carcinoma <unk>  is now classified as a subtype of lung adenoacarcinoma and the term<unk>  is no longer in use. It is also known as "lepidic predominant adenocarcinoma" due to its progression along the alveolar walls without invading stromal, pleural or vascular tissue. By definition,<unk>  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.
