Both single and multiple cysts are very common. The exact causes of cysts are not known, but they do tend to change with hormonal variations, either during normal menstrual cycles or from post-menopausal hormone replacement therapy . Cysts do not become cancer or increase the risk of cancer. Most of the time, cysts may be left alone, but sometimes a physician may drain them with a small needle using ultrasound guidance. This procedure is called cyst aspiration .
