There is a possibility after menopause to have hemmorhage in the vagina. In this case the patient should immediately inform the doctor, and have as soon as possible a pelvic exam and an atrial ultrasound.
During the pelvic exam we will determine whether the hemorrhage is caused by a trauma or an injury or polyp exists in the uterus.

Also during a vaginal ultrasound, the obstetrician will measure the thickness of the inner cervical or endometrial. The endometrium which is lack of estrogen during menopause should be less than 5 ml at its thickest point.

If there is no polyp in the cervix during gynecological examination or vaginal trauma that could be due to atrophy in the uterus of women in menaupause because of the low-estrogen, the female hormones. It is very important to be absolutely sure of the endometrial thickness. If the endometrial thickness is greater than 5 mm then an introspection of the internal uterine, a  hysteroscopy  should be performed in order to see if there is a problem within the uterine cavity.

Problems of this kind are polyps and endometrial cancer. It is very important to have a hysteroscopy in such cases because an incipient stage endometrial cancer is very easy to be cured by making a total hysterectomy.
But if a woman has vaginal hemorrhage and assume that it is nothing serious and does not inform the doctor, she may lose valuable time and endometrial cancer may develop so it is no longer curable and reduce life expectancy of the patient.
Especially women who have increased body weight ratio, ie increased weight, suffering from diabetes and not have children have more risk of getting this disease
