How to get a second opinion

Why does getting a second opinion matter?

A second opinion matters because a serious diagnosis leads to major treatment decisions, and those decisions can significantly affect your quality of life, your time, and your body. Getting a second specialist view before you commit is a reasonable, sensible check.

Second opinions can confirm a diagnosis, uncover alternative treatment options, introduce you to clinical trials you were not told about, or occasionally identify a different diagnosis entirely. Even when the second opinion agrees completely with the first, many people find that the confidence of having two specialists reach the same conclusion is itself valuable.

Research in medicine consistently shows that second opinions change management plans in a meaningful proportion of cases. For rare or complex diagnoses, the rate is even higher.

When should I seek a second opinion?

There is no wrong time to seek a second opinion, but the following situations particularly warrant one.

The diagnosis is rare, complex, or unusual. Your current specialist has limited experience with your specific condition. The recommended treatment is aggressive or has significant side effects. You feel uncertain, unheard, or rushed. The recommended treatment conflicts with what you want for your quality of life. You have been told there are no more treatment options. You are considering a clinical trial.

If you feel any doubt, that is enough reason. You do not need a specific justification.

How do I ask for a second opinion?

The most straightforward way is to go back to your GP and ask for a referral to a second specialist. Tell your GP you would like a second opinion and why. They should support this without hesitation. If they do not, that itself is useful information.

You do not need to tell your current specialist you are seeking a second opinion, though it is often better if you do. Many specialists will actively help you arrange one. A straightforward way to raise it: "I would like a second opinion before we finalise the treatment plan. Would you be able to recommend someone, or can I see someone at [specific hospital or centre]?"

You can also ask your GP to refer you directly to a different specialist at a different hospital, without involving your current specialist at all. That is your right.

What should I bring to a second opinion appointment?

The second specialist needs to review your case as thoroughly as your first. Bring everything.

Bring copies of all test results, pathology reports, imaging reports, and the actual scan images if possible (usually available on CD or USB from the radiology department). Bring a summary of your current diagnosis and treatment plan as you understand it. Bring a list of your current medications. Bring a list of your questions.

If possible, ask your current specialist or their rooms to send a referral letter to the second specialist before your appointment. This gives the second specialist context and ensures they have your full history.

Where can I get a second opinion in Australia?

For complex diagnoses, major public teaching hospitals are often the best place to seek a second opinion, particularly those with dedicated specialist centres. These hospitals have multidisciplinary teams who meet regularly to discuss difficult cases.

In Victoria, Peter MacCallum Cancer Centre accepts referrals from anywhere in Australia and sees patients from interstate. The Royal Melbourne Hospital and Alfred Hospital both have significant specialist teams.

In New South Wales, Chris O'Brien Lifehouse and Royal Prince Alfred Hospital in Sydney are major specialist centres. In Queensland, Princess Alexandra Hospital and Royal Brisbane and Women's Hospital. In Western Australia, Sir Charles Gairdner Hospital and Fiona Stanley Hospital. In South Australia, the Royal Adelaide Hospital.

For rare diseases or unusual presentations, consider whether there is a specialist at a teaching hospital interstate who has particular expertise in your specific condition. A telehealth second opinion is a legitimate option if travel is difficult.

What do I do if the two opinions disagree?

If the second specialist agrees with your first, you can proceed with greater confidence. If they disagree, that is important information, not a problem.

Differing opinions can mean different specialists weight the same evidence differently. It can mean the second specialist has more recent information about treatment options. Or, in rare cases, it can indicate a genuine diagnostic uncertainty that warrants further investigation.

When opinions differ, go back to both specialists and tell each one what the other said. Ask each to explain their reasoning. Ask what would change their view. In some cases, you may want to seek a third opinion, particularly from a specialist at a major centre with high volume experience in your condition.

Ultimately, treatment decisions are yours to make. Your job is to have enough information to make a decision you are comfortable with. Differing specialist opinions are not a problem to solve alone. Your GP can help you navigate them.

What will a second opinion cost and how long does it take?

A second opinion is covered by Medicare in the public system, and in the private system there is usually an out-of-pocket cost. It typically adds a week or two before you start treatment, which for most serious diagnoses will not meaningfully change outcomes. Ask the specialist's rooms about fees before your appointment. Healthdirect (healthdirect.gov.au) has a find-a-health-service tool that can help you locate public specialist services in your area.

Taking that time may significantly improve the quality of your decision. Ask your first specialist whether the timing is important given your specific situation.

If your situation is urgent and time-sensitive, tell the second specialist's rooms when you call to book. Ask for the earliest possible appointment and explain why.
