Most colon cancer develops without any family history in the individual. All of us need to be vigilant about the risk of colon cancer. Young people can also get colon cancer without a family history. In fact, over the last few years or decade, we have noticed an increased incidence of colon cancer in younger people under 50 and specifically in their 30s and 40s with advanced stage colon cancer. The exact reason for this is really not clear. We believe it's something about an environmental factor - either with diet or activity level - but still yet to be determined. So we may actually think about lowering the age of doing a screening colonoscopy for people less than 50 but that still has not been decided.
