Approximately 180,00 new cases of cancer are estimated to be reported annually and more than 40,000 women die each year of this disease in the United States. It is estimated that one out of every eight women in the United States will be diagnosed with breast cancer at some time in their lives.
Cells are the basic building blocks of all tissues of the human body.
The majority of cases of breast cancer arise from cells in the ductules and lobules of breast tissue, from which milk is produced when a woman is in her child-bearing years. It is spread of cancer to other organs, resulting in organ failure, which causes death from this disease. No one really knows what causes breast cancer. Certain risk factors have been identified, yet as many as seventy percent of women diagnosed with breast cancer have no identifiable risk factor. Consequently it is difficult to design breast cancer prevention programs.
