Endometrial cancer often manifests as vaginal bleeding after menopause, and in women who have not experienced menopause, it often presents as menstrual irregularities. The diagnostic methods for endometrial cancer include the following: 1. Fractional curettage is the most important method for diagnosing endometrial cancer. First, scrape the cervical canal, then sequentially scrape the endometrial tissue from each part of the uterine body, label the specimens separately, and send them for pathological examination together. 2. Cytological examination is a method for screening for endometrial cancer. A specially made uterine cavity suction tube or brush is inserted into the uterine cavity to collect secretions for cytological culture. 3. Hysteroscopic examination allows direct observation of the growth of endometrial lesions and can also obtain live tissue for pathological examination. It involves pelvic ultrasound examination to understand the size of the lesion, surrounding infiltration, etc. 5. Other methods, such as lymphangiography, CT, MRI, and serum CA125 testing.
