I just got a notice from the Gastro place that I am due for a colonscopy. My last was 5 years ago and all was well. I thought 10 years was the recommendation, looked it up and Cancer Society and CDC both say every 10 years. Is this like all the other guidelines that seem to be creeping downward into more "illness"? Blood Pressure is not a problem at 140/80 and blood sugar above 100 and cholesterol at 200? I'm 67, healthy and had a screening at 52 and 62. I just hate to be "feared" into getting something not necessary.
