From January 1991 to December 1993 409 post-menopausal women were observed at the Center for the Study of Climateric Disorders of the Department of Obstetrics and Gynecology of the University of L'Aquila. The aim of the study was to evaluate the incidence of gynecologic neoplasm among this group of women. A total of 48 women at risk for malignant tumors were detected. The relationship between the climateric age and the oncologic risk is discussed.
