i don't have too much knowledge but can tell you that i had a petscan that took a couple of hours and ruled out any metastacies. i would ask for that. i found once igot on a program i could better deal with the c word. ifinally realized that whatever happens happens and to take every day with my wife and three kids(8,5,and5)as a blessing.i was 40 when diagnosed and it has been a long 10 months since then.but i would not trade some of the experiences i've had for anything.have faith that things will work out and that your family and friends are there for you. also the people at this wonderful site.
