The issue is that you're an individual, whereas the "standard of care" that your doctor is duty-bound to provide is based on population studies. Your doctor may be able to adapt this care to your specific case if you have obvious specific secondary conditions. Ideally, your doctor would be able to tailor your care to your genetics, your lifestyle as well as to your medical history. That is the goal of "personalized medicine". This will likely become more and more common-place over the next decade or two, in particular with respect to the genetic aspect. But for now it remains too expensive and uncertain to be rolled-out by HMOs and national healthcare systems. So you end up with "generic" advice, which is in fact in most cases the best they can do.
