Hi Lizzie..Thanks for the note...I did google it ..But the only thing I seem to get is patients who have had removed and it being cancer...then there is a certain percentage of it coming back...But in my case...Mine was benign...Thank my Lord for that...I called my surgen yesterday the receptionist tells me that my second Cat Scan report said Patient has shadow and should follow up with further Cat Scans,...And that is all they tell me...I think i,m about ready to take a plane and go get a second opinion in Toronto....Frustrated...Karen
