Abnormal uterine bleeding (AUB) is a very frequent symptom in women. The prevalence of AUB is estimated at 12% in the general population and increases with age, reaching 24% in those aged 36–40 years. When it is a single episode of irregular blood loss in non-pregnant women, it is most of the time harmless, but it can also be a first sign of serious pathology such as cancer of the cervix.
