Histologic comparison of mammary carcinomas among a population of Southwestern American Indian, Spanish American, and Anglo women.
Primary carcinomas of the breast were studied in age-matched populations of Southwestern American Indian, Spanish American, and Anglo women from an area served by the New Mexico Tumor Registry. Histologic tumor type, nuclear grade, and stromal inflammatory response were compared among these three groups. Indian women presented with less favorable tumor stage at diagnosis. Histologic tumor types were similar with the the exception that lobular carcinoma was less frequent among Indian and Spanish American than among Anglo women. Carcinomas from Indian patients showed less differentiated nuclei than those from the other groups.
