When two medical opinions disagree, compare the questions first
Separate differences in records, interpretation, options and priorities before discussing conflicting recommendations with your clinicians.
Before seeking a tie-breaking opinion, ask whether both clinicians reviewed the same information and answered the same question. Write down the specific disagreement and ask each to explain it. This organises the next conversation; it does not determine which recommendation is correct.
If timing or symptoms are a concern, contact your treating clinician or appropriate urgent service. A comparison exercise should not delay urgent assessment or lead you to stop or change treatment on your own.
Put the recommendations beside their reasons
Copy the actual wording, or mark your summary as your own. Keep the date, records reviewed and stated limitations with each recommendation. Avoid reducing a nuanced opinion to “operate” or “do not operate” if the clinician made it conditional.
The National Cancer Institute notes that a cancer second opinion can agree with the initial plan or suggest a different approach. That establishes neither which opinion is right nor a rule for other specialties.
Identify what kind of difference needs explaining
These are editorial categories for a discussion, not a clinical classification or diagnosis.
| Possible difference | Question for the clinicians |
|---|---|
| Different records or assessment dates | Did you review the same material, and has anything changed? |
| Different interpretation of the same finding | What finding leads you to a different conclusion? |
| Different question or review scope | Are both opinions addressing the same decision? |
| Different options or timing | What are the reasons for the proposed sequence and time frame? |
| Different priorities or trade-offs | Have both discussions accounted for what matters to me? |
| Unresolved uncertainty | What remains unknown, and would more information change the advice? |
NICE's shared decision making guidance emphasises discussing options in relation to a person's goals and making uncertainty clear. The table applies that conversational approach; it is not a NICE-endorsed decision aid.

Ask for clarification before counting votes
You might say: “I have two recommendations and want to understand the reasons for the difference. Could we look at whether they use the same information and assumptions?” Ask whether direct communication between the clinicians would help, and what permission or records sharing they require.
A third opinion may be something to discuss, but another vote does not automatically resolve different information or different goals. Ask what an additional review would need to clarify and whether there is time for it. Confirm who remains responsible for your current care and the agreed next step.
Use the written opinion question sheet to check the scope of each review and the preparation guide to organise the records.
