The incidence of breast cancer among women in the United States appears to be rising. It is estimated that one out of every eight to nine women in this country develops breast cancer in her lifetime.

Any woman can get breast cancer.
Although it is much less common, males too can have breast cancer. Some women are more likely to develop breast cancer than others. The first sign of breast cancer is usually a lump in the breast.
