Just had abdominal pelvic sonogram which showed cyst on both ovaries 15.7/8.4/10.5 on the left, and 6.3/1.6/2.0 cm's on the right. CT Scan results of abd./pelvis were: cystadenoma, cystadenocarcinoma, or complex benign cyst. Was told results were "inconclusive" by Kaiser Permanente radiologist.That these were "differential" what does "differential mean" and is inconclusive because surgery is needed? Have heard that CA-125 levels are sometimes not accurate. GYN doctor has ordered CA-125 to determine if I need to be seen sooner than Nov 3, If surgery is next, should it be hysterectomy?
