Hi Barbara,... do you mean a P.E.T. scan of your body??? that they will do..just to scan your whole body for any other possible cancer... they give you a radioactive sugar injection.cancer likes sugar.. so it lights up with metabolism of the radioactive material.. or an M.R. I...of your breast.. which I also had.. there can be false positives.. but go to a very reputable center with strong radiologist... better safe than sorry... my M.R.I.. biopsy was positive.. as was as C. Applegate's... just very early detection...so If I just had a lumpectomy..I would have had a reoccurance later... with the M.R.I. spot.. I took the breast off.. called multicentric breast Ca...good luck, knowledge is power..love lia
