No one knows what causes breast cancer. But we do know that a woman’s risk of developing the disease is compounded by a number of factors—her age, genetic predisposition, age at start of menstruation.
The good news is that many of the risk factors can be controlled through diet, exercise, and alcohol and tobacco restriction or avoidance, respectively. Unfortunately, there are several factors that are either very difficult to control or are beyond a woman’s control, among them, her race, family history of cancer, as well as aspects of her own personal history, including her history of diseases, such as uterine and ovarian cancers. Her personal history also includes her current age, how old she was when she had her first child, age at the onset of menstruation and menopause, etc.
