The presence of sudden bleeding after 5 years of menopause does not mean the presence of cancer, just that bleeding after menopause has a tendency to become cancerous, not 100% of the time. It is necessary to go to the hospital for ultrasound examination to determine whether there is any abnormality in the shape of the uterine cavity, for example, there is separated fluid in the uterine cavity, uterine fibroids, endometrial polyps, which can cause bleeding, and at this time, you can restore normal health through surgery. However, in the case of no bleeding, TCT and HPV cancer screening should also be performed to rule out the chance that there will be cervical pre-cancer, so it is also necessary to carry out screening. If there is no abnormality in the shape of the uterine cavity, you can also consider hysteroscopy to remove a part of the uterine lining for laboratory tests to rule out the possibility of endometrial degeneration, which also needs to be examined.
