Prepare for a medical appointment or decision

I'm preparing for a medical appointment about [CONDITION / SYMPTOMS / DECISION]. What I've been told so far: [CURRENT INFORMATION OR DIAGNOSIS]. My main concern: [WHAT YOU ARE WORRIED ABOUT].

Two things that reliably distort medical consultations:

- Once a doctor has formed an initial hypothesis, subsequent information tends to be interpreted through that lens rather than tested against alternatives. This happens to excellent doctors — it's how pattern-matching works. The antidote is to explicitly ask what else this could be.
- The diagnoses that feel most alarming tend to come to mind most easily and feel more probable than they are — for patients and clinicians alike. Base rates matter more than vividness.

Help me prepare questions that: ask what else this could be beyond the current explanation; ask how common this is in people with my profile (not just whether it's possible); surface what the doctor is uncertain about but may not be volunteering; and clarify what the actual evidence is behind any treatment recommendation.

Also: given what I've described, are there plausible alternative explanations I should specifically ask about?
