(When a woman of 62 came to me with similar problem, all I did was, I DECALCIFIED her body, through various means I have described in several of my books.
THAT woman and her learned daughter were very much and pleasantly surprised to find the total disappearance of two HUGE breast lumps she had earlier, which were essentially due to her taking 500mg x 2 tablets of Calcium supplementations - all these happened within about 45 days!)
That is again why the menopausal women suffer massive heart attacks.
