Abstract : Mammography has proven to be reliable as a screening tool for breast cancer. However, the specificity of mammography for breast cancer may be as low as 10% as evidenced by the number of biopsies recommended compared to the number of cancers confirmed (Moskowitz and Gartside, 1982). Therefore, of significant health care benefit would be a method used in conjunction with mammography which could reduce the number of biopsies required while maintaining or improving survival rates. In terms of health care costs, Adler et al. (1990) estimated that more than half of the mammographic screening costs for breast cancer are the result of required biopsies or excisions due to low specificity. Again, an alternative method for establishing the type of lesion present would be of great benefit. Any improvement in early detection of breast cancer is clearly important as survival is significantly improved when cancers are detected in the 0.5 to 1 cm diameter size range (Axtel et al, 1976).
