Malignant tumors originating from endometrial glands are also called uterine body cancers, most of which are adenocarcinomas. It is one of the three major malignant tumors of the female genitalia. In my country, endometrial cancer is much lower than cervical cancer, but in some developed Western countries, this disease is higher than cervical cancer and ranks first among gynecological malignancies. The peak age is 58 to 61 years old, accounting for about 7% of the total number of female cancers and 20% to 30% of reproductive tract malignancies. The incidence rate has been on the rise in recent years, and has approached or even exceeded that of cervical cancer. It is related to long-term estrogen stimulation, obesity, hypertension, diabetes, infertility or sterility, menopause and other physical and genetic factors.
