If your FIT is + for occult blood you need further follow up and maybe a new PCP.
I have reported this to my pcp and he still does not seemed concerned, and does not believe I need a colonoscopy.
...BUTT ... be pro-active and be your own best advocate
...and if you'd like .... tell your PCP that YOU would not be concerned if HE had a + FIT result either.
also : " You will miss MORE for not looking... than not knowing ! "
If he doesn't even LOOK for a cause how the hell would he expect to find it ?????
JMO, which you did ask for
Best wishes moving forward
my vote is : get the scope and / or a new doctor who will listen to your concerns and do what is needed
