Definition

Cancer has spread to the upper two-thirds of the vagina or to the tissue around the uterus. Stage II is divided into stages IIA and IIB, based on how far the cancer has spread. In stage IIA, cancer has spread from the cervix to the upper two-thirds of the vagina but has not spread to the tissue around the uterus. Stage IIA is divided into stages IIA1 and IIA2, based on the size of the tumor. In stage IIA1, the tumor is 4 centimeters or smaller. In stage IIA2, the tumor is larger than 4 centimeters. In stage IIB, cancer has spread from the cervix to the tissue around the uterus.
