In this episode of KP Research Radio, Sue Rochman speaks with DOR Research Scientists Bette Caan, DrPH, and Elizabeth Cespedes Feliciano, ScD, whose studies have shown that body composition — which incorporates both muscle and adipose tissue, or fat — is a better measure than Body Mass Index (BMI) for studying weight, cancer risk, and cancer outcomes. Their findings are opening up new avenues for research on ways to improve cancer survivorship.
