Brief Summary of Protocol:
Obesity is a risk factor for poor patient outcomes in specific cancers of the breast and colon. Changes in the levels of several blood components such as insulin, molecules of inflammation and fat cells may influence tumor growth. These varying levels may tell us what effect these factors have on either the tumor itself or surrounding tissue cells. A better understanding of the link between obesity, blood levels of these factors and tumor growth could lead to new treatments. For example, if insulin is found to influence tumor growth, a drug like Metformin, which reduces insulin levels, might be useful to prevent tumor growth in the obese. To better understand the underlying biology, this study will compare the effects of blood from obese men and postmenopausal women to men and postmenopausal women of normal weight on tumor growth and possibly the surrounding tissues.
