50 yrs old every 10 yrs is right unless there is a family history. I was diagnosed with colon/rectal cancer when I was 46 yrs old. It has been recommended to my children that they get their first colonoscopy at around 35 yrs old.

Hi for myself I prefer an AMAS test to check for cancer since I have not the least wish for medicines which cause all kinds of body problems. This is a simple blood test and is cheaper anyway. If there is no cancer the test can be done again later if desired and is highly accurate according to reports.
Sometimes a colonoscope can't always get to the other side anyway and is therefore almost useless in some cases since the other side can't be viewed.
I had the amas blood test two years before I was diagnosed, it was negetive. Because of the large mass in my rectum, it is estimated that I had cancer for at least seven years before diagnosis. If I had a coloscopy earlier, it would have been detected. I might be an anomoly, but I don't think so. I don't think anything when dealing with colon cancer can be as effective as a colonoscopy.
