The authors review any possible correlation between prolactin and growth hormone in human breast cancer. They find neither a significant relationship between growth hormone and breast cancer nor between prolactin and growth hormone. In many cases however, prolactin levels may be used as a neoplastic marker. The excess of prolactin could originate either in a tumor factor stimulating its secretion by the hypophysis or in an ectopic production of the hormone by tumor tissue.
