Endometrial cancer symptoms can be judged by clinical manifestations, and endometrial cancer can be initially diagnosed by ultrasound. Transvaginal ultrasound can understand the size of uterus, whether there are superfluous organisms in the uterine cavity, thickness of endometrium, whether there is infiltration of myometrium, size and nature of adnexal masses, etc. It is the most commonly used non-invasive auxiliary examination method. It has high accuracy, especially in understanding myometrial infiltration and clinical staging. Typical ultrasound image of endometrial cancer is the presence of uneven echogenic area in the uterine cavity, and color Doppler imaging can show abundant blood flow signals. In addition to ultrasound examination, diagnosis can usually be confirmed by diagnostic curettage, scraping the tissues in the cervical canal, and then scraping the tissues from the two corners of the uterus and the anterior and posterior walls of the uterus for pathologic examination. Patients with endometrial cancer often have vaginal bleeding and menstrual disorders as their main clinical manifestations, often accompanied by lower abdominal distension and pain. When such symptoms occur, they should go to specialized hospitals for examination and treatment.
