I agree with Angie's sage advice. Most cysts
are benign. However, a cyst that is growing
should be removed. A CT scan can help triage waiting for surgery versus surgery right away. That is, if the CT scan is perfect - no fluid, no thickening in the bowel walls or the lining of the abdomen, no enlarged lymph nodes - then waiting a few more months is fine.
What was your CA 125 result?
