Pronunciation
Definition 1
Stage II is divided into stages II and IIE. In stage II, cancer is found in two or more lymph node groups, and both are either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). In stage IIE, cancer is found in one or more lymph node groups either above or below the diaphragm and outside the lymph nodes in an organ or area on the same side of the diaphragm as the lymph nodes with cancer. (NCI Dictionary)
Definition 2
Ann Arbor Classification: Stage II: Involvement of two or more lymph node regions on the same side of the diaphragm (II); or localized involvement of a single extralymphatic organ or site in association with regional lymph node involvement with or without involvement of other lymph node regions on the same side of the diaphragm (IIE). The number of regions involved may be indicated by a subscript (e.g., II3). (NCI Thesaurus)
