The doctor patient relationship has become like an assembly line. There is no intimacy and that ever widening gap makes it hard for a doctor to care about their parients. Back when doctors used to make house calls, things were different.
These days doctors try to see as many patients a day as possible. They schedule 15 or 20 an hour and barely recognize you at your follow up.
Most do not even feel the need to look into symptoms you describe. You are seriously worried about something, they can't get you out of the room fast enough.
It's really sad
Hypocondriacs and insurance frauders didn't help the doctor/patient relationship over the years either.
Like everything else in this world, it all comes down to money.
There will never be a cure for cancer, diabetes, etc as long as it remains more profitable to just treat symptoms.
I'd like to see some other countries that view us in angst to come up with the cure for AIDS or cancer to piss off our government, instead of building and launching nukes.
