There are 4 main stages to uterine cancer, each of which is subdivided. In this article we will learn about the first two stages to this cancer.In stage I, based on how far the cancer has spread into the wall of the uterus, the uterine cancer is limited to just the uterus and has not spread to other organs or outside the uterus walls. This main stage is divided into IA, IB, and IC.In stage IA, the cancer affected just the inner tissue of the uterus and has not spread to anywhere else in the body. This is the earliest stage of the cancer.In stage IB, less then half of the muscular tissue is affected by cancer and the uterine cavity measures 8 or less centimeters.In stage IC, more the half of the muscular tissue is affected by cancer and the uterine cavity is larger than 8 centimeters.In stage II, the cancer has progressed to include the cervix area of the uterus. This stage is divided into IIA, IIB and IIC.In stage IIA, the cancer involves the uterus and only the surface lining of the cervix. In IIB, the cancer extends into deep layers of the cervix. At this time the disease has not yet spread.The next stages we will cover are stages III and IV in another article. Remember that your treatment options will depend on the stage at which the cancer is in as well as its severity, that being low medium or high. Your doctor will be able to tell you more.
