If endometrial (uterine) cancer is diagnosed, your doctor needs to learn the extent (stage) of the disease to help you choose the best treatment. The stage is based on whether the cancer has invaded nearby tissues or spread to other parts of the body.
When cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary (original) tumor. For example, if uterine cancer spreads to the lung, the cancer cells in the lung are actually uterine cancer cells. The disease is metastatic uterine cancer, not lung cancer. It’s treated as uterine cancer, not as lung cancer. Doctors sometimes call the new tumor “distant” disease.

After the uterus is removed, it is checked to see how deeply the tumor has grown. Also, the other tissue samples are checked for cancer cells.
These are the stages of uterine cancer:
