Adenocarcinoma in situ (AIS) of the lung —previously included in the category of "bronchioloalveolar carcinoma" (BAC)—is a subtype of lung adenocarcinoma.It tends to arise in the distal bronchioles or alveoli and is defined by a non-invasive growth pattern.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
In “Type 2” the bronchus is contained in the tumor. These types are more common in malignant nodules. A compressed and narrowed bronchus is defined as “Type 3”, and can occur in both benign and malignant nodules. Narrowing of the proximal bronchial tree is described as “type 4” and is associated with malignancy.
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction.Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.
A lobule of the lung enclosed in septa and supplied by a terminal bronchiole that branches into the respiratory bronchioles. Each respiratory bronchiole supplies the alveoli held in each acinus accompanied by a pulmonary artery branch. The pulmonary lobule is the portion of the lung ventilated by one bronchiole.
Note the five lung lobes divided by the three lung fissures and the main, lobar and segmental bronchi. Anatomic resections refer to procedures where a section of the lung is removed with respect to lobar or segmental anatomy. [20] These include pneumonectomies, lobectomies and segmentectomies and are commonly used for the treatment of NSCLC.

Despite the medical advances of detection, diagnosis and treatment methods throughout the past 50 years, lung cancer causes more deaths than any other cancer in both men and women. [5] Currently, lung cancer is the most common form of cancer diagnosed in the United States and a major cause of death, accounting for 14% of all cancers.
