Because the amount of atmospheric carbon is well known and conservation of matter requires a balanced global carbon budget, this previously unaccounted for source of carbon to the atmosphere implies the existence of an additional continental carbon sink such as higher rates of biomass accrual in forests.
(World Cancer Research Fund/American Institute for Cancer Research (2007) Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective. AICR: Washington, DC). AICR/WCRF was the first organization to note that, after smoking, obesity is the most important preventable cause of cancer. While obesity is clearly linked to risk for developing many forms of cancer, the deleterious impact of obesity on prognosis has proven even more compelling in several studies.
What is known about the relationship between obesity and cancer? How might obesity increase the risk of cancer? How many cancer cases may be due to obesity? Does avoiding weight gain or losing weight decrease the risk of cancer? How does obesity affect cancer survivorship? What research is being done on obesity and cancer? What is obesity? Obesity is a condition in which a person has an unhealthy amount and/or distribution of body fat. To measure obesity, researchers commonly use a scale known as the body mass index (BMI). BMI is calculated by dividing a personâs weight (in kilograms) by their height (in meters) squared (commonly expressed as kg/m2). BMI provides a more accurate measure of obesity than weight alone, and for most people it is a fairly good (although indirect) indicator of body fatness.
