Lack of Association of Physical Activity and Obesity with Incident Pancreatic Cancer in Elderly Women

Abstract
Animal models have suggested that insulin and insulin resistance may play roles in the etiology of pancreatic cancer (3, 4) and epidemiologic studies have shown an association between diabetes mellitus and increased risk of pancreatic cancer (5-7). Obesity, measured by body mass index (BMI) and waist-to-hip ratio (WHR), and physical activity can play roles in both insulin resistance and type II diabetes (8, 9).
