Therefore if your relative was diagnosed at age 36 or younger, you should be screened now, otherwise you do not yet need colonoscopy and your insurance is unlikely to approve the procedure
unless it is medically necessary. The procedure
is not a big deal, although the prep is unpleasant.
At 26 you are unlikely to have colon cancer, even with a family history, however you should have a fecal occult blood test and if it is positive your doctor should follow up. Good luck.
