Some general information from WebMD:
Stage 3:
Symptoms. Along with unusual vaginal bleeding or discharge, you may have pelvic or belly
pain. Other signs include
bloating, pain during
sex, feeling full quickly when eating, and changes in your bowel or bladder habits. You may also
lose weight or feel the tumor in your belly.
Treatment. If your doctor thinks that the cancer can be taken out with surgery, a surgeon may do a total or radical hysterectomy and remove your fallopian tubes and ovaries. They may also do a pelvic washing. This is followed by chemotherapy or radiation.
If the surgeon thinks that your cancer is too widespread, you may get radiation. This may help shrink the tumor enough for surgery.
Stage 4:
The cancer is in the bladder, rectum, or organs far from the uterus, such as the
lungs.
Stage IVA: The cancer has spread to the bladder or rectum, and possibly nearby lymph nodes.
Stage IVB: It's found in the upper abdomen, the
fat that supports your lower abdomen (called the omentum), or organs like your lungs,
liver, and bones. It may have spread to the groin lymph nodes.
Symptoms. They're the same as stage III. You may also have symptoms in the areas where the cancer has spread, such as pain in your bones or shortness of breath.
Treatment. For most people with stage IV endometrial cancer, the cancer has spread too far for a surgeon to remove it all, but you may still get surgery similar to the kind in earlier stages, as well as radiation, to keep you from bleeding too much.
