Both obesity and alcohol use can increase estrogen levels in the blood, which can contribute to an increased risk of breast cancer. Estrogen promotes cell division and growth in breast tissue, which can increase the likelihood of genetic mutations that can lead to cancer. Therefore, it is important for women to maintain a healthy weight and limit their alcohol consumption as ways to reduce their breast cancer risk.
