Stage I uterine cancer
T1, N0, M0: The cancer is only growing in the body of the uterus. It may also be growing into the glands of the cervix but is not growing into the supporting connective tissue of the cervix. The cancer has not spread to lymph nodes or distant sites.
- Stage IA (T1a, N0, M0): In this earliest form of stage I, the cancer is in the endometrium (inner lining of the uterus) and may have grown from the endometrium less than halfway through the underlying muscle layer of the uterus (the myometrium). It has not spread to lymph nodes or distant sites.
- Stage IB (T1b, N0, M0): The cancer has grown from the endometrium into the myometrium, growing more than halfway through the myometrium. The cancer has not spread beyond the body of the uterus.
