Cell lung cancer stage II non-small. Definition

Medical Definition: Cell lung cancer stage II non-small

Stage II is divided into stages IIA and IIB. In stage IIA, the tumor is 3 centimeters or smaller and the cancer has spread to lymph nodes near the same side of the chest as the tumor. In stage IIB, cancer has spread to lymph nodes near the same side of the chest as the tumor and one or more of the following situations: (1) the tumor is larger than 3 centimeters, (2) cancer has spread to the main bronchus of the lung and 2 centimeters or more from the carina (where the trachea joins the bronchi), (3) the cancer has spread to the deeper layer of the membrane lining the lungs, or (4) the tumor partly blocks the bronchus or bronchioles and part of the lung has collapsed or has developed pneumonitis (inflammation of the lung). Or, in stage IIB, cancer has NOT spread to lymph nodes and one or more of the following situations: (1) the tumor may be any size and cancer has spread to the chest wall, or diaphragm, or the pleura between the lungs, or the membranes lining the heart (2) the cancer has spread to the main bronchus of the lung and to no more than 2 centimeters from the carina (where the trachea joins the bronchi ), but has not spread to the trachea, or (3) Cancer blocks the bronchus or bronchioles and the whole lung has collapsed or developed pneumonitis (inflammation of the lung).
