Purpose: To investigate the biomagnetic activity produced physiologically by the various normally occurring states of the female breast: puberty, reproductive age, pregnancy, lactation and menopause. Method: The mammary glands of 90 healthy women were examined using a Superconducting Quantum Interference Device (SQUID). Results: Biomagnetic activity was low at puberty (105.46+-3.77 fT/sqrootHz) and the menopause (111.66+-25.06 fT/sqrootHz), but was high during the reproductive years (142.13+-20.70 fT/sqrootHz), particularly in the hyperplastic states of late pregnancy (221.86+-12.14 fT/sqrootHz) and lactation (252.73+-54.77 fT/sqrootHz). The results were statistically significant (p<0.0001 ANOVA test). Conclusion: Our observations indicate the importance of SQUID in understanding the biomagnetic activity of the female breast at the various physiological states of life.
