Trial of Vaginal Estrogen for Urogenital Symptom Relief in Women on Aromatase Inhibitors

Vagifem, is the most appropriate medication to treat bladder and vaginal symptoms such as vaginal dryness and urinary discomfort. The purpose of this research study is to see the benefit this three month vaginal estrogen tablet, Vagifem, has on the bladder, vaginal symptoms and health. The investigators also want to monitor whether the bones might be impacted by estrogen or its absence. If there is an effect on bones, it means that some estrogen may be absorbed from the tablet to affect other places in the body. The investigators are hoping to prove this is not the case. The investigators will also be measuring the quality of life of women participating in the study.
