We just found out that my dad has cancer again. :Bawling: This is his 4th cancer. He's had mouth, skin, bladder and colon cancer. They took a tumor out of his bladder last week. It turned out to be a very aggressive type that would have killed him quick if we hadn't caught it early. We are terrified that if he gets a tumor somewhere that doesn't show symptons early, that the next one will get him permanently. Is there any screening test that will show tumors? Like a full body scan of some type that he could get every year as a screening. MRI or CATscan or ultra sound? Has anyone here done something like that?
