Cancer Second Opinion

Overview

A cancer diagnosis is life-changing, and the treatment decisions that follow are among the most important you will ever make. An expert second opinion helps confirm that you have the most accurate diagnosis and the most appropriate plan before beginning chemotherapy, radiation or surgery. Reviews can lead to a changed diagnosis or a modified treatment plan in a notable share of cases, though every case is different.

This page explains how a cancer second opinion works so you can decide whether it is right for you. It is educational only and is not medical advice; a second opinion informs the decisions you make with your treating oncologist and does not replace their care.

Who May Consider It

• You have a new cancer diagnosis and want to confirm it before starting treatment.
• Your recommended plan involves major surgery, chemotherapy or radiation.
• You have a rare or complex cancer type, such as sarcoma, glioblastoma or pancreatic cancer.
• Your cancer has not responded to initial treatment as expected.
• You are considering a clinical trial or exploring options not available locally.
• You have been told there are no further options and want another perspective.
• You are planning to travel abroad for cancer treatment and want pre-travel confirmation.

Documents You May Need

• Pathology report — the full report, with the actual slides available for re-review if possible.
• Imaging studies and reports — CT, MRI, PET-CT, ultrasound or X-ray, including images on disc and the radiology reports.
• Biopsy results — including immunohistochemistry and molecular testing.
• Treatment plan — your oncologist’s recommended protocol, including drugs, doses, radiation plan or surgical approach.
• Medical history summary — previous cancers, treatments and response to treatment.
• Current medications and staging workup results, such as TNM staging, tumour markers and genetic testing.

How the Review Works

• Submit your case — complete the form with your diagnosis and upload your reports and imaging.
• Specialist matching — you are matched with a board-certified oncologist specialising in your cancer type (medical, surgical or radiation oncology as appropriate).
• Comprehensive review — the specialist reviews your pathology, imaging, staging and proposed treatment plan.
• Written report — you receive a detailed report, typically within 48–72 hours, covering confirmation or questioning of the diagnosis, staging accuracy, evaluation of the plan, alternative options and recommended next steps.

What It Can & Cannot Do

A second opinion is a review of your existing information, not a substitute for hands-on care. It can confirm or question the diagnosis and type, assess whether staging is accurate and complete, evaluate whether the proposed treatment follows current guidelines, suggest alternative or additional options, and identify clinical trials you may be eligible for.

It cannot replace your treating oncologist, provide emergency cancer care, guarantee a specific outcome or cure, prescribe medications or order tests directly, or establish a doctor-patient relationship. If you are planning treatment abroad, our hospital directory and cost guides can help you compare accredited cancer centres, and you can request a personalised written quote.

Privacy & Confidentiality

Your medical information, including pathology and imaging, is handled with strict confidentiality. Data is encrypted during transmission and storage and shared only with the reviewing oncologist assigned to your case. You control who else receives the report, and you can request deletion of your data.
