IN LAST MONTH'S ISSUE OF LIFE EXTENSION magazine, we repeated our recommendation that prostate cancer patients should have there prolactin blood levels checked, as excess amounts of this hormone can promote prostate cancer cell proliferation and prevent successful treatment.
A new study indicates that high levels of prolactin predispose healthy women to an increased risk of breast cancer. Prolactin is produced by the pituitary gland and, along with other hormones, stimulates the growth of the mammary glands and the production of milk after childbirth.
