Uterine cancer, also known as womb cancer, is any type of "cancer that emerges from the tissue of the "uterus. It can refer to several types of cancer, with "cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries. "Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from "developed countries.
Risk factors depend on specific type, but "obesity, older age, and "human papillomavirus infection add the greatest risk of developing uterine cancer. Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop. If caught early, most types of uterine cancer can be cured using surgical or medical methods. When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of "chemotherapy, "radiation therapy, or "surgery may be required.
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.
The terms uterine cancer and womb cancer may refer to any of several different types of "cancer which occur in the "uterus, namely:
- 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.

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).
