    Can smoking cause Bowel Cancer?

    I have recently seen a doctor re rectal bleeding and a number of other symptoms synonymous with bowel cancer. I am currently awaiting test results and will be going in for a colonoscopy in a number of weeks. Although I am relatively young for this condition (34), there is a history of it in our family. I have looked on line regarding other contributing causes to bowel cancer but have found conflicting answers -- in short - is smoking a noted/significant cause of bowel cancer?
