What is your doctor recommending at this point? If you are not comfortable with the findings of the ultrasound, there is always needle aspiration of the cysts, or biopsy. These are the only means being absolutely certain, but typically cysts show on ultrasound as fluid-filled, while cancers are solid. How old are you? Do the lumps come and go with your monthly cycle? Are they painful sometimes, and other times not? These symptoms would also be consistent with cysts.
Hope this helps!
