Mammography is the most accurate method currently available to detect breast disease when no symptoms exist. Mammography aides in evaluating a lump; it may also detect other areas that are not yet palpable. The possibility that you may have breast cancer is indeed very frightening, but keep in mind that most breast disease is not malignant (cancer).
The following new Mammography Guidelines for women with no symptoms are based on the consensus of a number of medical organizations:
Annual mammography for all women age 40 and over.
If you have a family history of breast cancer, or if you have had breast cancer before,
mammography may be recommended sooner than age 40.
Perform BSE (Breast Self-Examination) monthly
CBE (Clinical Breast Examination) annually by your health care provider
