usually seeing blood in stool it is rectal cancer. Wasn't sure if you mention colon or rectal cancer (I just saw you put sigmoid colon, so its colon cancer). It doesn't sound like you have any metastases with that low CEA. Mine was 26 when originally diagnosed and I had no metastases. Even went up to 32 with no metastases. Now its over 500 and I am sure it will be down since I started chemo.
My doctor saw me on 12/19/2016 and tentatively scheduled surgery for the 1/3/2017. I was stage 3 at the time because of lymph node enlarged. After MRI, Cat Scan and Pet scan they wanted to do neoadjuvant chemo (radiation/chemo pills xeloda).
neoadjuvant is usually used for rectal cancer to shrink tumor so you have good margins to remove and leave some rectum intact, depending where it is located in the rectum.
It's a rough road, chemoradiation is rough. At some point radiation will cause pain when you go to have a bowel movement, but you will get passed it. Use creams and things they tell you to do. Listen to your doctors.
