There is a book written by Dr. John R.Lee, WHAT YOUR DOCTOR MAY NOT TELL YOU ABOUT MENOPAUSE, that has information in it about fibrocystic breasts. He also has a site on the net, John Lee MD.. In his book he states that he has found that your problem is often a sign of estrogen dominance; relatively high estrogen and low progesterone. You will find his book very interesting and informative. You do not have to be in menopause to experience low levels of progesterone and estrogen dominance. This problem is widespread in women all over the world as is cancer. I advise you to have your hormone levels checked if you have not done so already. I had mine checked and found out that all my hormones were down. I began his program of using natural progesterone cream prescribed through my doctor a year ago. I just had my hormone levels checked again, and they all came back normal this time. I am feeling much better and my breasts are not sore anymore.
