This hit home. My dad was diagnosed with colon cancer last week and had a large portion of his colon removed last Thursday. Polyps, which often become cancerous given time, can take a few years to get there. So you don't have to get screened every year but should definitely get the ball rolling. They'll usually be able to take them out during the procedure.

The guidlines are where i live (Austria) First Colo at 45, if nothing found -> Every 5 years. Once a poly is found and removed get one every 2-3 years.
