How necessary is an additional Colonoscopy screening if I’ve already gone through a CT scan for cancer?

They found a suspicious mass on my spine at an MRI screening for my back. I’ve gone through a full-body CT scan that turned out clear, but now I’m being told I’ll also need a colonoscopy. Is this necessary now, as I’m already struggling with a broken back? Would the CT scan give an idea about colorectal cancer risk, without the need for a colonoscopy?

Total body CT is not an approved tool to screen for colon cancer. Special CT called CT colonography is required.

Yes, you should have a colonoscopy because the CT scan can miss masses. The colonoscopy inflates the colon so you can actually see polyps or masses.
