That's certainly good news you don't have diabetes, but if I were you I would my doctors exactly what tests were run and what were the results (not just 'normal' but the numbers, the ranges, even better ask for copies of the lab reports). For example, even a slightly elevated fasting blood sugar can be a predicter of future diabetes that can be prevented by dietary changes. Changes in your blood work over time can be another good indicator, another good reason to have it all in your files. I ignored borderline results for years (at my doctors insistence), and in my case it would have been better if I changed my diet sooner.

Regarding mammograms and false positives. Yeh, we have to all make our own decisions, but I will continue to be screened for whatever I can be screened for. In my case I was sick of years and years of borderline abnormal paps. Finally, when I had a hysterectomy for a variety of reasons, only in part due to the abnormal paps, they checked the tissue and indeed found cells in the very early stages of cervical cancer, but the good news is they were surrounded by a ring of normal cells so it means they removed it all.
