question: My husband was diagnosed with bladder cancer in June and since has had the tumors removed and they say that the cancer is invasive in the wall, he is doing chemo now and is scheduled to finish in Oct. they want to remove his bladder in November, I have asked for a PET scan and was told because it is so expensive, they just do the CAT scan, My concerns are, If the cancer is in other parts of the body, I dont believe the bladder should be remover, I think that we should get a second opinion, but my primary doctor keeps putting me off and not calling back. I would like to have your opionion of the PET scan
