Effect of abdominal transplanted mammary tumor on peritoneal fluid cytology in mice

In this study C3H/HeJ female mice received an intraperitoneal injection of mammary tumor suspended in saline; After 14 days, the presence of mammary neoplasm was detected by a significant change in the cytodifferential counts of aspirated peritoneal fluid. Previous studies suggest that ovarian cancer can be detected in mice and in women by the characteristic changes produced in abdominal cellular fluid distribution.
