|Patient UK||Uterine cancer|
- Endometrial carcinomas originate from cells in the glands of the endometrium (uterine lining). These include the common and readily treatable well-differentiated endometrioid adenocarcinoma, as well as the more aggressive uterine papillary serous carcinoma and uterine clear-cell carcinoma.
- Endometrial stromal sarcomas originate from the connective tissues of the endometrium, and are far less common than endometrial carcinomas.
- Malignant mixed Müllerian tumors are rare endometrial tumors which show both glandular (carcinomatous) and stromal (sarcomatous) differentiation – carcinosarcoma behaves similar to a high grade carcinoma, and it is felt to be of epithelial origin rather than true sarcoma.
- Cervical cancer arises from the transformation zone of the cervix, the lower portion of the uterus and connects to the upper aspect of the vagina.
- Uterine sarcomas: sarcomas of the myometrium, or muscular layer of the uterus, are most commonly leiomyosarcomas.
- Gestational trophoblastic disease relates to neoplastic processes originating from tissue of a pregnancy that often is located in the uterus.
It is not known with certainty what the causes for uterine cancer may be, though hormone imbalance is speculated as a risk factor. Estrogen receptors, known to be present on the surfaces of the cells of this type of cancer, are thought to interact with the hormone causing increased cell growth, which can then result in cancer. The exact mechanism of how this occurs is not understood.
Uterine cancer resulted in about 58,000 deaths in 2010 up from 45,000 in 1990.
Uterine cancer is the fourth most common cancer in women in the UK (around 8,500 women were diagnosed with the disease in 2011), and it is the tenth most common cause of cancer death in women (around 2,000 people died in 2012).
