Abstract

Although the usefulness of mammography as screening test for breast cancer is still in dispute,its use to patients over 50 years of age is valid.

Since Wolfe fisrt classified breast parenchymal pattern of mammography into 4 patterns, N1, Pl, P2, DY, many authors have adopted the clitoris in studing the changes of the parenchymal patterns for certain ages and the risk for breast cancer of certain parenchymal patterns.

Authors reviewed 50 cases of breast cancer which diagnosed by radiologic studies including mammography, galactography, and computed tomography, and confirmed by pathologically.

The results were as follows :

1) Incidence of breast cancer according to parenchymal pattern was : 9 cases(18%) in N1 type breast 5 cases(10%) in Pl type breast 32 cases(64%) in P2 type breast, 4 cases(8%)in DY type breast.

2) Detection rate of cancer lesion according to parenchymal pattern was : 89% in N1 typebreast, 80% in Pl type breast 63% in P2 type breast 25% in DY type breast.

Most frequent age distribution was 5th and 6th decade.

In conclusion, mammographic parenchymal pattern is valid indicator for breast cancer.
