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. Certain hormones are a contributing factor to obesity, and estrogen appears to help determine your body fat distribution.
Obesity leads to the reduction of SHBG (sex hormone binding globulin) a protein that binds estrogen levels and keeps them out of circulation. When these levels go down, estrogen levels go up, become active, and thus stimulate the growth of breast cancer cells. Over one hundred studies have investigated the links between obesity and breast cancer.
