Purpose : This study is to describe authors'experience on mammographic findings of breast cancer and to knowif there is difference between 35 years of age or younger and older groups. Materials and Methods : Mammograms of72 patients with breast cancer detected from January, 1991 to December, 1993 were retrospectively analysed.Mammographic findings were classified into mass only, mass with microcalcifications, microcalcifications only andothers. Marginal characteristics of mass were classified into spiculated, poorly marginated and well marginated.Shape of microcalcifications were classified into casting, granular and mixed types. These findings were comparedbetween 35 years of age or younger and older groups. Results : Mammogram showed mass only in 33 patients(46%), mass with microcalcifications in 26 patients(36%), microcalcifications only in seven(10%) and other findings insix(8%). Other findings wear architectural distortion, asymmetric high density and incidental breast carcinomafrom paraffinoma in one patient respectively, and dense breast in three patients. The margins of the breast masswere spiculated in ten(17%) poorly marginated in 30(51%), well-marginated in 19(32%). Shape of microcalcificationswere casting type in 13(40%), granular in 14(42%) and mixed in six(18%) cases. 3 patients had dense breast withwhich mammography did not demonstrate the lesion. 3 patients without mammographically demonstrable lesion due todense breasts were under 35years in age. and there was statistically significant difference between the twogroups(p-value<0.05). Microcalcifications only was more common findings in 35 years of age or younger. Conclusion: The most important mammographic findings of breast cancer were mass and microcalcifications. Architecturaldistortion and asymmetric high density were additional findings. In 35 years of age or younger, microcalcifications only was an important finding because mass lesions are frequently masked by dense breast. Thusother imaging modalities, such as ultrasonography, were required.
