If endometrial cancer spreads, it tends to first go to places near the uterus. This may be the fallopian tubes, ovaries, cervix, or vagina. It can then spread to the lymph nodes, bladder, or rectum. Advanced stages of endometrial cancer can spread as far as the bones and lungs. Most cases of endometrial cancer are found in the early stages before they have spread outside the uterus.
Cancer that spreads to other parts of the body is called metastatic cancer. The process is called metastasis. Metastasis is a complex process. The cancer cells of the tumor grow into other tissues, blood vessels, and the lymph system. They then travel through the bloodstream or lymph system to reach other parts of the body where they grow into new tumors.
