“…A tendency for women with breast cancer to secrete more growth hormone in response to a glucose load has been described by Greenwood, James, * Meggitt, Miller, and Taylor (1968) and Pearson, Llerena, Samaan, and Gonzales (1968), and recently * Murray, Mozaffarian, and Pearson (1972) have also reported increased levels of circulating prolactin in this disease. In our experience the growth hormone response to insulin hypoglycemia was normal in women with advanced malignancy of the breast (Stewart, Benson, Roberts, Forrest, and Greenwood, 1971) and circulating prolactin, estimated either by with benign disease of the breast, and those with (Forrest, 1972;Boyns, Cole, Griffiths, Roberts, Buchan, Wilson, and Forrest, 1973;Wilson et al, 1973). Recent results using a homologous assay are shown in the table.…”
