Staging
If uterine cancer is diagnosed, the doctor needs to know the stage, or extent, of the disease to plan the best treatment. Staging is a careful attempt to find out whether the cancer has spread, and if so, to what parts of the body.
The doctor may order blood and urine tests and chest x-rays. The woman also may have other x-rays, CT scans, an ultrasound test, magnetic resonance imaging (MRI), sigmoidoscopy, or colonoscopy.
In most cases, the most reliable way to stage this disease is to remove the uterus (hysterectomy). (The description of surgery in the "Methods of Treatment" section has more information.) After the uterus has been removed, the surgeon can look for obvious signs that the cancer has invaded the muscle of the uterus. The surgeon also can check the lymph nodes and other organs in the pelvic area for signs of cancer. A pathologist uses a microscope to examine the uterus and other tissues removed by the surgeon.
These are the main features of each stage of the disease:
Stage I -- The cancer is only in the body of the uterus. It is not in the cervix.
Stage II -- The cancer has spread from the body of the uterus to the cervix.
Stage III -- The cancer has spread outside the uterus, but not outside the pelvis (and not to the bladder or rectum). Lymph nodes in the pelvis may contain cancer cells.
Stage IV -- The cancer has spread into the bladder or rectum. Or it has spread beyond the pelvis to other body parts.
