Uterine cancer
All cancer begins in cells, cells make up tissues, and tissues make up all organs of the body. Uterine cancer is the most common cancer of the female reproductive system. The uterus is the female reproductive organ in which a baby grows if a woman becomes pregnant. The uterus consists of three main parts, the cervix is the lower portion of the uterus, the broad middle part is the corpus or body, and the dome-shaped top of the uterus is the fundus. When a woman develops uterine cancer, a tumor is formed on her uterus of abnormal or old cells and can either be benign or malignant.

Types

There several different types of uterine cancer. The most common form, endometrial carcinoma, originates in the glands of the lining of the uterus, also known as the endometrium. Less common forms of uterine cancer include uterine sarcomas, such as leiomyosarcomas, which develop from the muscle layer of the uterus (myometrium), or sarcomas of the endometrial stroma (non-glandular endometrium). Malignant mixed müllerian tumors are unusual endometrial tumors which show both glandular (carcinomatous) and stromal (sarcomatous) differentiation - their true cell of origin is unknown.
