Postmenopausal bleeding can be examined by gynecology, urine routine and ultrasound, and based on the results of the examination, a professional doctor will make a judgment whether it is cancer or not. Gynecological examination can check the condition of vagina, uterus, fallopian tubes, ovaries and pelvic cavity lining, urine routine examination can rule out whether there is infection, liver and gallbladder diseases, trichomonas infection, etc. Combined with ultrasound examination, it can check whether there is thickening of endometrial lining, ovarian cysts, pelvic masses, etc. Through the results of comprehensive examination, professional doctors will diagnose whether the bleeding after menopause is caused by cancer. Postmenopausal bleeding does not necessarily mean cancer. After menopause, the estrogen level in a woman’s body will decrease, which may lead to a decrease in body resistance and easily cause bacterial infection resulting in endometritis, vaginitis, etc., leading to bleeding, and uterine atrophy may also cause bleeding. It is recommended that patients go to the hospital in time to be diagnosed by the doctor, do not judge on your own, so as not to delay the condition.
