Danny, about Pet scans, Packer was never offered one in the past 5 years til we went to Dana Farber, they did Pet, Cat, and MRI, from what I understand is that Pet will pick up cancer cells sooner that Cat and MRI....Packer had a clear Cat Scan in March, and the end of July he another, which picked up a 16 mm tumor,I wonder if a Pet scan in March would have picked it up sooner.....it hasn`t grown much since July, so something tells me it was there in March and the Cat didn`t pick it up.............Dana Farber does all 3 tests, to compare results..........Dee
