Breast cancer screening: <i>Preliminary report of 207 biopsies performed in 4,128 volunteer screenees</i>

Abstract

Thirty-six carcinomas of the breast were pathologically verified in the first 207 biopsies performed to date on women attending the Breast Cancer Detection Center at The University of Cincinnati. Fifty-three percent of these have been minimal breast cancer, 14 being totally in situ. This is compared with a similar number of breast biopsies performed prior to the opening of the Breast Cancer Project. In the latter group of cases there were 45 carcinomas proven, only 1 of which was in situ, 24 of which were invasive Stage I and 20 Stage II or higher. In addition, 65 biopsies demonstrated proliferative disease of varying degrees of severity as compared to a total of 13 in the non screened population.
