When you receive a cancer diagnosis, the instinct is to move fast. Start treatment. Trust the team in front of you. And often, that's the right call.
But speed without scrutiny is not the same as good care. A second opinion isn't about doubt — it's about due diligence on the most important decision you may ever face.
Why second opinions matter in oncology
Studies consistently show that second opinions in cancer change the diagnosis, staging, or recommended treatment plan in a significant proportion of cases. This isn't because the first team was incompetent — it's because cancer is complex, multidisciplinary, and evolving rapidly.
Different centres have access to different clinical trials. Different oncologists specialise in different subtypes. What's considered standard at one hospital may not reflect the most current evidence available elsewhere.
How to get a second opinion through the NHS
You have the right to a second opinion on the NHS. Your GP or current consultant can refer you to another specialist — ideally at a different hospital trust with a specialist cancer centre for your specific type.
Key considerations: request that all imaging, pathology slides, and test results are transferred rather than repeated where possible. Ask specifically for a centre that runs clinical trials in your cancer type, as this indicates they're at the frontier of treatment.
Going private for a second opinion
A private second opinion consultation typically costs between £250 and £500. For this, you should receive a full review of your case, a written report, and a clear explanation of whether the recommended treatment plan is appropriate — or whether alternatives should be considered.
The most valuable private second opinions come from consultants who also work in the NHS at major cancer centres. They bring institutional knowledge and access to multidisciplinary team discussions that solo private practitioners may not have.
What a meaningful second opinion should include
A second opinion that simply says "I agree with the plan" isn't worth the appointment. A meaningful review should cover whether the staging is accurate, whether the proposed treatment reflects current guidelines and evidence, whether there are clinical trials you'd be eligible for, whether the surgical approach (if applicable) is optimal, and whether the sequencing of treatment is correct.
What I do for clients navigating cancer
I research the specific cancer type and subtype, identify the leading UK and international specialists, prepare a structured case summary for the second opinion appointment, review whether current treatment aligns with the latest published evidence, and identify relevant clinical trials. The goal is never to override your clinical team — it's to ensure every option has been properly considered.
