Endometrial cancer still has some early clinical symptoms that facilitate early detection: for example, irregular vaginal bleeding after menopause or menopausal menstrual disorders; irregular bleeding after long-term oral tamoxifen; irregular menstruation in infertile patients, such as polycystic ovary syndrome, long-term amenorrhea, but sudden irregular bleeding, etc., which should be examined early. Screening methods include doing ultrasound, which can look at the endometrium for abnormal echogenicity, inhomogeneous thickening, which needs to be identified as polyps or polyp-like hyperplasia of the endometrium, as well as inhomogeneous masses, disorganized echogenicity, or even abnormal blood flow signals, or changes in the hardness and elasticity of the endometrium, although it is not thickened. Ultrasound or ultrasound doctor will suggest early lesions, and CA125 tumor marker testing can be continued. In addition, hysteroscopic screening can also be done. Hysteroscopy is considered to be a better method to diagnose endometrial cancer. Because of its minimally invasive nature, hysteroscopy can be performed from under the microscope with direct view of the uterine cavity to avoid missing the early lesions. All in all, there are still early diagnosis methods for endometrial cancer, and if early symptoms appear, you must go to the hospital to ask the doctor for examination.
