I just had the same issue.They told me that there was still a small amount of ovary adhered to the lining of my inside. When they pulled blood and
took hormone levels it showed still producing enough to cause a regrowth. This produced enough hormone to generate a new cyst
, being the size of a walnut between my kidney and
intestine causing severe pain and
nausea. I just came home from the hospital yesterday and
am awaiting results from the biopsy.
