Abstract
From 1960 to 1989, 563 cases of primary breast cancer in our clinic were divided into the young group (under 35 years of age) and the elder group (over 35 years of age), and compared for clinicopathological features.
The results were: 1) Breast cancer in young patients represented 10.5% (59 cases) of all 563 breast cancer in young patients; 2) there was no significant difference in the cumulative survival rate between young and elder groups; and 3) There was a tendency to have poor prognosis in the young group compared to the other when they had a tumor occupying the total area of the breast, or an advanced cancer of n1β, n2, Stage IIIa, or Stage IIIb.
