Will CT Scans from BC pick up other cancers?

It depends on how much of your body is being scanned. I had a pre-op chest CT because I was a smoker, and my MO wanted more detail than an x-ray would show. It caught the top half of my kidney, with a good-sized tumor sitting on it. So I had to have another CT, this time with contrast, later that month before meeting with the urologist. But that first CT was only for the upper torso. That one also showed an aortic aneurysm, so now I've got a cardiothoracic surgeon in my life. I'm trying to get them all to cooperate and coordinate my CTs, because the kidney protocol is scans every six months for three to five years, and the aneurysm gets scanned annually to monitor its growth. I'll probably die from contrast exposure first!

Your scan probably just showed the upper loop of the bowel. According to my MO, they don't order CTs after treatment unless there are symptoms or other indicators to justify it.

and...I was worried about the same thing during treatment for bc. I was diagnosed at 50 and was planning on my colonoscopy that year...then I had to wait until treatments and surgery was over. I looked back at my ct scan and got some comfort until I had my colonoscopy post treatment.

Yes... my pcp, gyn and oncologist still advised me to get the colonoscopy. My guess is that there are tiny precancerous lesions that a ct might not pick up in the colon? The most deadly and aggressive colon cancers start out as flat lesions that are very hard to see...which is why the colon cleanse is critical. The regular polyps are much easier to spot.

My aunt had colon cancer so I didn't want to take any chances.

For what it's worth, a lot of the symptoms of colon cancer also are symptoms of other noncancerous gastrointestinal conditions that are treatable.
