Energy balance refers to the integrated effects of diet, physical activity, and genetics on growth and body weight over an individual's lifetime. Scientists are increasingly aware of the importance of understanding the effects of energy balance on the development and progression of cancer and on cancer patients' quality of life after treatment. Weight, body composition, physical activity, and diet affect many physiologic systems and can alter the cancer process at many points.

Weight and Obesity

  • Obesity and Cancer Risk
    A fact sheet that summarizes research on the potential link between obesity and cancer risk.
  • Cancer Trends Progress Report: Weight
    This section of the Cancer Trends Progress Report focuses on the relationship between overweight and obesity and cancer risk.
  • Risk Factor Monitoring and Methods Branch: Obesity Policy Research
    The Risk Factor Monitoring Methods Branch (RFMMB) is part of the Applied Research Program within NCI's Division of Cancer Control and Population Sciences. RFMMB supports research on diet and physical activity that may inform policymaking at local, state or federal levels.
  • Obesity Research at the National Institutes of Health (NIH)
    This Web site has information about NIH-supported research to facilitate progress toward obesity prevention and treatment.
  • We Can!
