Endometrial cancer is a type of cancer that develops in the cells of the inner lining of the uterus (called endometrium). The cells in endometrium begin to grow in an uncontrolled manner with this type of cancer. Endometrial cancer is sometimes called uterine cancer also. But there is a difference between the two.
Endometrial cancers may be formed from epithelial cells (carcinomas), mixed epithelial and mesenchymal tumours (carcinosarcomas), or mesenchymal tumours. Traditional classification of endometrial cancer is based either on clinical and endocrine features (such as types I and II) or on histopathological characteristics (such as endometrioid, serous, or clear-cell adenocarcinoma).
Endometrial cancer often metastasizes to ovaries and fallopian tubes when the cancer is located in the upper part of the uterus, and the cervix when the cancer is in the lower part of the uterus. Usually, endometrial cancer first spreads into the myometrium and the serosa, and then to other pelvic organs.
The lung is a common site for endometrial cancer metastasis. According to a study published in the Journal of Chinese medicine, pulmonary failure was reported to be observed in 1.9–9% of patients with first recurrence of the endometrial cancer. Endometrial cancer metastasis to lungs can cause severe lung complications.
Here is a list of commonly used terms in endometrial cancer and uterus cancer and their definitions. Endometrial cancer is quite common in women within a specific age group in the United States.
