Most endometrial cancers are slow-growing, and some specific pathologic types, such as plasmacytoid carcinoma, clear cell carcinoma, carcinosarcoma, and high-grade endometrioid carcinoma, can develop rapidly. Most endometrial cancers, such as highly differentiated carcinomas, are slow-growing, confined to the endometrium or remain in the uterine cavity for a long time. Some specific pathologic types such as plasma carcinoma, clear cell carcinoma, carcinosarcoma, and high-grade endometrioid carcinoma may develop rapidly and metastasize in a short period of time. The main metastatic pathways of endometrial cancer are direct spread, lymphatic metastasis, and in advanced stages, hematogenous metastasis. Endometrial cancer is mostly seen in perimenopausal and postmenopausal women, with vaginal bleeding and abnormal vaginal fluid as the main clinical manifestations. Early stage patients are mainly treated by surgery. The prognosis of endometrial cancer is better if it can be detected early and treated well at an early stage.
