Second Opinion in Oncology: Steps to Guide You When Choosing Your Treatment Team

Published: 19.09.2026Dr. Ebru Gül Karakoç

Receiving a cancer diagnosis or managing a demanding course of treatment can be full of uncertainty for patients and their families; for this reason, seeking a second or even a third medical opinion is an entirely natural step in oncology, supported both scientifically and clinically. At our clinic we do not frown upon our patients seeking opinions from other physicians or from international centers; on the contrary, we see this step as a healthy sign of the patient's active participation in their own treatment. The oncology literature and psycho-oncology research show that second opinions largely confirm the existing treatment, thereby easing the patient's psychological burden and anxiety, and that in complex or rare cases they can provide vital refinements that optimize the treatment strategy. In this article we explain how you can assess the experience of the centers you consult when seeking a second opinion, and which criteria to look at when choosing the team that will carry out your treatment.


1. A Global Perspective and the Experience of Centers

Today, patients can obtain international opinions by sending their files to the world's leading cancer centers. Advanced oncology centers, our clinic among them, exchange views with respected reference centers abroad and with international Molecular Tumor Boards (MTB) in order to perfect their treatment scenarios.

When seeking an opinion from another physician or from abroad, what really matters is not merely how well known the center is, but its in-depth clinical experience with your specific type of cancer and, above all, in the field of "personalized oncology".


2. Steps to Guide You When Making Your Decision

Once you have gathered different opinions, choosing the team and the doctor who will actually carry out your treatment means assessing not only the medical plan on offer, but also the vision and philosophy of the clinic that will put that plan into practice. In this process, you may wish to keep the following criteria in mind:

  • Genomic Infrastructure and Team (MTB) Support: Does the doctor make the treatment decision alone, or is there a strong scientific team behind them? Are the credentials and scientific expertise of the members of the multidisciplinary board that makes these decisions (cancer geneticists, pathologists, oncology specialists) satisfactory and in line with international standards?
  • Scientific Activity and Depth: Does the clinic you are consulting conduct scientific research? Does it publish the results obtained from its own patient data in international peer-reviewed journals?
  • Innovative Vision: Is the center content merely to follow developments in oncology, or does it actually put them into practice? Does it give all of its patients only standard chemotherapy protocols, or does it have experience with genomic mapping, smart drug combinations and innovative treatments?
  • Case Experience and Side Effect Management: How much practical experience does the clinic have in reading complex genetic data and in managing the toxicity of targeted drugs and immunotherapies before a crisis arises (proactively, by means of pharmacogenomic tests)?
  • Transparent and Empathetic Communication: Is the physician you choose someone who answers all of your questions clearly, conveys the scientific data to you with due regard for the patient's state of mind, and makes you feel confident?

When you make your final decision after gathering all the scientific opinions, continuing with a physician who offers innovative treatments with scientific depth, who has a qualified team behind them, and with whom you feel safe when communicating will raise your belief in the treatment and your motivation to recover to the highest level.
