I was a lab rat, got a PhD, and I can't think of practicing anything else in medicine other than Pathology.
I get to confirm cancer diagnoses on tissue biopsies so patients can start getting the treatments they need. Occasionally I get to make diagnoses that are totally unexpected by my clinical colleagues, which is cool. Most of the time the biopsies are benign, which is good news for patients.
Sure, there's not a lot of patient contact (there are the occasional FNAs and bone marrow biopsies), but that doesn't mean I'm totally isolated. I'm usually on the phone (in my office... where I work out of) talking with other doctors about frozen section results, preliminary diagnoses, getting more clinical history to make a better diagnosis, or recommending re-biopsies (missed lesion or insufficient tumor for further characterization).
I understand Pathology is not for everyone. Yeah, if looking into the microscope makes you physically sick, then Pathology is probably not for you. If you can't do without patient contact or praise from patients, or if you absolutely have the need for people to know you went to medical school, then Pathology's probably not for you. Personally I don't have any interest in the rounding, charting, med prescribing, followups, clinics, or [insert clinical activity here] that my clinical colleagues need to do day after day. And I'm glad to leave all that stuff to them. 🙂
