The Centers for Disease Control and Prevention estimates around 35 percent of American adults are obese, meaning they have a body mass index higher than 30. Obesity is the leading cause of preventable death and contributes to health problems such as diabetes and heart disease.

One of the most significant questions raised by the new study is what, if any, effect the striking rise in estrogen has on a woman's risk of breast cancer. Studies show that estrogen therapy protects against heart disease and osteoporosis but may increase the risk of breast cancer. Some research also shows that moderate alcohol consumption -- one drink a day for a woman -- may decrease the risk of heart disease and increase the risk of breast cancer, as well.
