[Mammography in diagnosis of breast cancer]

Radiographic features of 50 breast cancers were evaluated in comparison with 83 benign lesions and the diagnostic accuracy is discussed. Most of the usual primary and secondary findings of cancer such as spicula formation, microcalcifications, skin, thickening and nipple retraction were present in these 50 cancer lesions and all of them were recognized in the benign lesions as well, although less frequently. Because breast parenchyma was dense in 81% of the cases evaluated, and mostly due to moderate to severe dysplasia, the diagnosis of the breast lesions was difficult. Therefore, we must be cautious in calling a lesion benign. The radiographic detectability of cancer was 94%, and the diagnostic accuracy was 72%, which are comparable to the results reported from other places.
