What is the womb?
The womb is part of the female reproductive system together with the ovaries, the fallopian tubes, the cervix and the vagina. The womb is also called the uterus. It is a muscular, pear-shaped organ found in your lower abdomen, between your bladder and back passage (rectum).
The lining of your womb is called the endometrium. Every month this lining thickens and grows and then falls away from the womb as a monthly period. There are also layers of muscle in the womb. The lower part of the womb is called the cervix or sometimes 'the neck of the womb'. During pregnancy, your womb protects the growing baby.
What is cancer of the womb?
When cancer develops in the womb, the cells change and grow in an abnormal way. A group of these cancer cells can form a tumour. Womb cancer is often called cancer of the uterus or uterine cancer. There are different types of womb cancer but the most common type is endometrial cancer. This affects the lining of the womb or endometrium. When cancer cells occur in the muscle layers of the womb, it is called sarcoma of the womb. The most common type is leiomyosarcoma.
Other types include:
- papillary serous carcinoma
- endometrioid adenocarcinoma
- clear cell carcinoma
There are also some benign conditions of the womb such as endometriosis and fibroids.
