Cysts are normal for all of us. They can cause problems as we get older because our hormone balance is not what it was when we were younger. This is especially true during menopause and after that stage of our life. Your mom is clearly in this latter group. She clearly needs to follow the recommendations of the Gynecologist on the management of this situation. There may be some "natural/homeopathic" things that she can use to manage this situation, but she should do this in the light of modern medicine as well.
