The womb (uterus) is a pear-shaped organ where a baby is carried during pregnancy. It is low in the pelvis (the area between the hips) and is supported by the pelvic floor muscles.

Most womb cancers start in glandular cells found in the lining of the womb (the endometrium). They are called endometrial cancers. There are different types of endometrial cancers. Endometrial cancer is usually diagnosed early and treated successfully.
