We conducted a case-control study to examine the relationship between breast density (BD) on mammography and breast cancer risk for postmenopausal Japanese women. The mammograms (205 cases and 223 controls) were classified by two doctors employing Wolfe's classification and used to measure BD with original computer software. A weak relationship between breast cancer risk and the parenchymal pattern of Wolfe's classification was found. The BD measured with the computer software, however, showed a significant relationship with breast cancer risk.
