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 an
d 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 an
d intestine causing severe pain an
d nausea. I just came home from the hospital yesterday an
d am awaiting results from the biopsy.
