✦ Synopsis

Abstract

Plasma prolactin was measured in 2,572 premenopausal, 628 menopausal, and 1,666 peri‐ and postmenopausal women who were apparently healthy. Breast cancer was subsequently diagnosed in 47 of these women at a median time of 5 years after blood collection (pre‐cancer cases). Prolactin levels in pre‐menopausal cases increased significantly with age whereas this was not found in matched controls. The perimenopausal cases were characterized by extreme variability in prolactin levels. In post‐menopausal women who developed breast cancer, the prolactin levels were significantly elevated, being at or above the 70th percentile for the controls. In this group the results are consistent with prolactin acting as a late‐stage tumour promoter.

## Abstract The amount of prolactin has been determined in serial blood samples taken over 24 h from 20 pre‐ and 9 post‐menopausal women volunteers. All women had a large increase in prolactin at night (24.00 h‐03.00 h). A much smaller rise in prolactin occurred in the evening (18.00 h‐20.00 h) whi
