Early breast cancer usually does not cause pain and may cause no symptoms at all.
Breast cancer ranks second among cancer deaths in women after lung cancer.
Factors that appear to raise a woman's risk for breast cancer include advancing age, family history, benign breast conditions, and a late menopause.
It is important to remember that a lump or other changes in the breast, or an abnormal area on a mammogram, may be caused by cancer or by other, less serious problems.
