Adenocarcinoma in situ of the lung
A true diagnosis of AIS can only be made once the entire tumor has been surgically removed, because it must be evaluated for evidence of microscopic invasion into the adjacent normal lung. This marked change was done in order to isolate BAC as a purely non-invasive tumor with better prognosis.
