Re: color doppler ultrasound to detect prostate cancer?

The key words here are "detecting signs of colon cancer or rectal
cancer".
You still need to get a biopsy, so you just wasted your time getting
the
virtual bull***, and will need an endoscopic colonoscopy anyway to get
a
biopsy

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".
