[Studies into carcino-embryonic antigen (CEA) and enzyme activities of alkaline and acid phosphatase in patients with fibrocystic breast disease (author's transl)].

CEA as well as alkaline and acid phosphatase were measured in patients with fibrocystic breast disease. The values recorded from the punctured fluids were compared to those in peripheral blood. CEA concentrations in cyst fluid were elevated in patients with proliferative breast disease, whereas no correlations could be established between alkaline and acid phosphatase, on the one hand, and various histological forms of breast disease, on the other.
