The fact that approximately 20% to 50% of women suffer from the symptoms generated by fibroid tumors at some stage of their lives suggests that they are quite common growths in the reproductive system of a woman.

These tumors of the uterus tend to shrink after menopause. http://www.blossomivfindia.com/pages/fibroids-and-fertility
