This will provide a rationale and opportunity for earlier screening, and reduce colon cancer morbidity and mortality secondary to the Lynch syndrome gene.', 'detailedDescription': 'This is an observational cohort study. Tissue specimens obtained that have been labeled with the diagnosis of endometrial hyperplasia will be identified and their chart reviewed for demographic date of age, race, body mass index, and co-morbidities.
