stage IIA non-small cell lung cancer

(... sel lung KAN-ser)

Stage II non-small cell lung cancer is divided into stages IIA and IIB. In stage IIA, cancer has spread to lymph nodes on the same side of the chest as the tumor. Also, one or more of the following is true: (1) the tumor is not larger than 5 centimeters; (2) cancer has spread to the main bronchus and is at least 2 centimeters below where the trachea joins the bronchus; (3) cancer has spread to the innermost layer of the membrane that covers the lung; and/or (4) part of the lung has collapsed or become inflamed. OR in stage IIA, cancer has not spread to lymph nodes and one or more of the following is true: (1) the tumor is larger than 5 centimeters but not larger than 7 centimeters; (2) cancer has spread to the main bronchus and is at least 2 centimeters below where the trachea joins the bronchus; (3) cancer has spread to the innermost layer of the membrane that covers the lung; and/or (4) part of the lung has collapsed or become inflamed.

Two-panel drawing of stage IIA non-small cell lung cancer. First panel shows cancer (5 cm or less), and cancer in the right main bronchus and lymph nodes; also shown are the trachea, bronchioles, and diaphragm. Second panel shows cancer (more than 5 cm but not more than 7 cm), and cancer in the left main bronchus; also shown are the trachea, lymph nodes, bronchioles, and diaphragm. Insets show cancer that has spread from the lung into the innermost layer of the lung lining; a rib is also shown.

Stage IIA non-small cell lung cancer. Cancer has spread to certain lymph nodes on the same side of the chest as the primary tumor; the cancer is (a) 5 cm or smaller, (b) has spread to the main bronchus, and/or (c) has spread to the innermost layer of the lung lining. OR, cancer has not spread to lymph nodes; the cancer is (d) larger than 5 cm but not larger than 7 cm, (e) has spread to the main bronchus, and/or (f) has spread to the innermost layer of the lung lining. Part of the lung may have collapsed or become inflamed (not shown).
