女性生殖系统的肿瘤约占女性肿瘤的一半左右,而子宫体癌是女性生殖道中仅次于子宫颈癌的常见的恶性肿瘤。本病好发在老年妇女。近年来不少作者指出本病发生率在上升,而子宫颈癌发生率相反下降。1965年Christopherson等指出:10年内子宫体癌发生率增加13％,而且有继续上升趋势。如日本东京肿瘤医院报道1949—1965年间子宫体癌占肿瘤发生率4.7％,而1966—1972年 Female reproductive system tumors account for about half of female tumors, while the uterine body cancer is the female genital tract, second only to cervical cancer common malignancy.
