You still need to get a biopsy, so you just wasted your time getting

The question is if you don't detect any signs of colon cancer or rectal
cancer, then you don't need a biopsy. Here's another example, when you
go to the dentist and he thinks there might be a cavity but can't see
it, he has two choices. Drill and look or get more information by
taking an xray. I think an xray would be prudent to confirm a cavity.
I'm not saying technology is all inclusive, but I sure would avail
myself of all the non invasive exams prior ot any "procedures".

There is a BIG difference between a cavity in a tooth and a tumor.
The scans (eg X-Rays, etc) are usually done in an attempt to find
tumors. After tumors are found--a biopsy is done or the tumor is
removed. The cells are examined under a microscope to determine if
cancer cells are present or not present.
