Now, I know that blood tests cant diagnose you with cancer (except for leukemia and whatnot) but if you did have cancer, would you think there would be some red flags in a blood test? Or something suspicious? I got results back today for A LOT of things, not just CBC, and everything came back normal and fine except for some iron deficiency. If I had cancer, would my blood test results differ? Just looking for some reassurance of course lol. Health anxiety sucks
