Histologic differences in breast carcinoma of Japanese and American women

Abstract

Series of breast carcinoma cases from Nagoya, Japan, and New York were compared histologically. Japanese women showed significantly more lymphocytic infiltration around invasive mammary carcinomas (p < 0.01), confirming previous studies, a finding suggestive of greater host resistance to breast cancer among Japanese women.
