Very recent studies have suggested that circulating RCP levels and the immunohistochemical staining of RCP in biopsy specimens may provide new markers for breast cancer diagnosis and prognosis. Termination of pregnancy has been demonstrated by immuno-neutralization of RCP in monkeys.
New research suggests that measuring circulating RCP levels and the presence of RCP in biopsy specimens can be used as indicators for breast cancer diagnosis and prediction of its course.  Immuno-neutralization of RCP in monkeys has demonstrated the ability to terminate pregnancy.
