Breast Cancer: Causes & Risk Factors
Breast density: In the past, the denseness of breast tissue was considered only a problem in being able to accurately see within breast tissue if there is evidence of early stage breast cancer growing. As of the end of 2010, it has been formally considered a risk factor for developing breast cancer.
Lifestyle choices: Unhealthy lifestyle choices may cause additional "wear and tear" on your body, which in turn can increase your chances of developing breast cancer. Alcohol consumption, doctors believe, is one example. Compared to women who do not drink, women who consume two or more alcoholic drinks per day have a 25% higher risk of developing breast cancer over the course of their lifetimes. Obesity and sedentary life style are also two factors that may increase your risk.
