Type-I cystic adenomatoid malformation CAM has recently been identified as a precursor lesion for the development of mucinous AIS, but these cases are rare. A multi-step carcinogenesis hypothesis suggests a progression from pulmonary atypical adenomatous hyperplasia AAH through AIS to invasive adenocarcinoma ACbut to date this has not been formally demonstrated.

This information is mostly in reference to the now outdated entity of BAC, which included some invasive forms of disease.

The CT angiogram sign. Malignant versus benign nodules at CT screening for lung cancer: AIS is considered a pre-invasive malignant lesion that, after further mutation and progression, is thought to progress into an invasive adenocarcinomx. Growth rate of small lung cancers detected on mass CT screening. J Comput Assist Tomogr ; Services on Demand Journal. Another distinguishing feature about BAC is that it afflicts men and women in equal proportions, some recent studies even suggest slightly higher incidence among women.

Small adenocarcinoma of the lung. While pure BAC is rare, the increase in incidence as seen in various studies can be due to unclear histological classification till WHO came up with its classification in and laveolar in Eur J Cardiothorac Surg. Recent research has made it clear that nonmucinous and mucinous BAC are very different types of lung afenocarcinoma.
