American Cancer Society Breast Health Guidelines | UCSF Health
The following information was contributed by the American Cancer Society.
The goal of screening examinations for early breast cancer detection is to find cancers before they start to cause symptoms. Breast cancers that are detected because they cause symptoms tend to be relatively larger and likely to have spread beyond the breast. In contrast, breast cancers found during screening examinations are more likely to be small and still confined to the breast.
The American Cancer Society believes the use of mammography, clinical breast examination and breast self-examination offers women the best opportunity for reducing the breast cancer death rate through early detection. This combined approach is clearly better than any one examination. The American Cancer Society does not recommend relying solely on any of these methods.
