The most common cause for the patient to present to the doctor is vaginal blood loss. This is an unexpected and worrying symptom for women past the menopause and a symptom that the doctor will always take seriously. In other instances, the patient complains of a vaginal discharge which may or may not be tinged with blood. In pre-menopausal women, the complaint may be of intermenstrual blood loss or discharge and a change to the pattern of the menses.
