Endometrial cancer, also known as uterine body cancer, refers to cancer of the endometrium, the majority of which is adenocarcinoma. It is one of the three most common malignant tumors of the female reproductive tract. The high incidence age is 58-61 years old. Endometrial cancer is more likely to occur in women who are obese, hypertensive, diabetic, unmarried, with few births, delayed menopause, suffering from polycystic ovary syndrome, anovulatory uterine hyperplasia, endometrial hyperplasia, taking single estrogen without progesterone antagonism for a long time after menopause, and having family history of tumor. In the early stage, there are usually no obvious symptoms, only incidentally discovered during screening or other reasons. Once symptoms appear, they are mostly postmenopausal vaginal bleeding and vaginal discharge. Treatment should be based on the stage of the tumor and the general condition of the patient. The main treatment is surgery, radiotherapy and drug therapy, which can be used alone or in combination. For women with perimenopausal menstrual disorders or irregular vaginal bleeding after menopause, endometrial cancer should be excluded and then treated as a benign disease, and segmental scraping is the most common and reliable method to confirm endometrial cancer.
