METHODS: We used Danish medical registries to conduct a population-based cohort study of women with a first hospital-diagnosed postmenopausal bleeding during 1995-2013. We computed the absolute risk of cancer and the standardised incidence ratio (SIR) comparing the observed cancer incidence with that expected in the general population.

CONCLUSIONS: In the Danish population, women with a first hospital-diagnosed postmenopausal bleeding have an increased 0-3 months risk of gynaecological, urological, gastrointestinal and haematological cancers.
