Endometrial cancer occurs within the uterus (hollow cavity compose of muscle in the pelvic area where fetus develops). Endometrial cancer develops in the endometrium, the inner lining of the uterus. Certain times, it is known as uterine cancer.
As endometrial cancer causes unusual bleeding from the vagina therefore it can be detected at the first stage. When endometrial cancer is found in early stage, surgical removal of the uterus tends to cure the cancer.
The definite causes of endometrial cancer are unknown. The mutation of endometrial cell causes uncontrolled duplication resulting in forming a mass of cells also known as a tumor. This tumor then begins to invade and destroy the normal cell. These cells have the tendency to metastasize (spread to other parts of the body).
When a rare type of tumor in the ovaries release estrogen, the risk of developing endometrial cancer increases.
