If one is breastfeeding and can not undergo a colonoscopy, what would be the best (and easiest) test to undergo to rule out symptomatic colon cancer.

Diagnosis bycamera: Talk to your hospitals x-ray department and ask them if you can swallow a capsule that contains a miniature camera and takes pictures of you GI tract.

You can have one: If you're breastfeeding, you can have a colonoscopy. You should pump and discard for 24 hours after receiving sedation drugs. The preparation for colonoscopy is not harmful. If you have symptoms, you should see a gastroenterologist or colon/rectal surgeon right away. Don't wait until you finish breastfeeding.

Maybe not related: See a gastroenterilogist. The short anesthetic used is not likely a contraindication to breast feeding. Also can ask your pediatrician. If a colonoscooy is indicated then it is probably alright. Swallowing a camera does not visuslize the colon, only small intestine. Ct colonography involves bowel prep with x-ray & contrast exposure.

Pump?: If the concerns for colon cancer are so great as to warrant an intervention such as a colonoscopy, perhaps you could use formula or pre-pumped breast milk during the period of time you are unable to breast feed.
