The term “vacation” is generally used to refer to menstruation in women. If menstruation comes back after four or five years of menopause, it may be related to atrophic vaginitis or cervical cancer. 1. Atrophic vaginitis: when estrogen level decreases after menopause and local resistance decreases, the vaginal wall shrinks, and the vulva itches, burns and feels uncomfortable, and pus and blood vaginal discharge may appear, which can be mistaken for menstrual blood. 2. Cervical cancer: a common gynecological malignant tumor, women may have vaginal bleeding, such as contact bleeding, vaginal bleeding after sex, or irregular vaginal bleeding. There may be other reasons for vaginal bleeding after stopping menstruation. It is recommended to go to the hospital specialist in time to improve the relevant examination, and then treat with targeted treatment under the guidance of professional doctors for a clear diagnosis, so as to avoid delaying the condition.
