A Second Opinion in Oncology: What to Expect from an Online Consultation

This is why more patients seek a second opinion from oncologists to confirm whether their prescribed therapy is correct or explore alternative options. This is not a sign of distrust in their treating physician, but rather a safeguard against potential errors and an opportunity to learn about other available treatments.

Modern technology has simplified access to expert evaluations. Patients no longer need to travel abroad to consult with world-renowned specialists. An online oncology consultation allows them to receive opinions from leading global clinics without leaving home. This article explains how online second opinions in oncology work, what to expect, and why this step could be pivotal on the path to recovery.

Why a Second Opinion Is Crucial in Oncology

Oncology is one of the most complex and rapidly evolving fields in medicine. Even experienced specialists may encounter rare cases requiring additional expertise. Here’s why a second opinion in oncology is particularly important:

Risk of Mistakes in Initial Diagnosis

A 2024 review published in Frontiers in Public Health found that diagnostic mistakes in oncology can reach 10–30%, depending on the tumor type and case complexity. This doesn’t necessarily indicate the physician's incompetence—often, it involves rare cancer forms, a typical clinical picture, or limited experience with specific tumors.

Misinterpretation of biopsy, CT, or MRI results can lead to ineffective or excessive treatment. A second opinion helps confirm or refute the initial diagnosis with a fresh expert perspective.

Complex and Rare Cases

Oncology frequently involves complex cases. Not all tumors fit standard patterns—some are rare, such as sarcomas or neuroendocrine tumors, where standard protocols may fail. Certain tumors are so uncommon that even skilled oncologists may encounter them only a few times in their careers.

In such cases, the expertise of specialists from major oncology centers—who focus on rare cancers, have access to cutting-edge diagnostics, and participate in clinical trials—is invaluable.

Impact on Treatment Choices

Modern oncology offers multiple treatment approaches. Even with an accurate diagnosis, recommendations can vary. One specialist may suggest radical surgery, another may recommend starting with chemotherapy to shrink the tumor, and a third, identifying specific genetic mutations, may propose targeted or immunotherapy.

A second opinion helps determine whether the proposed treatment plan is optimal or if there are more effective, less invasive alternatives.

The Online Oncology Consultation: How It Works

Many patients feel that an online format isn't suitable for a serious condition like cancer. A common question is, “How can a doctor advise me without seeing me in person?” In reality, 90% of second opinions in oncology are based on the analysis of medical documents, not a physical examination. Modern platforms like MedicusUnion have streamlined this process to be simple and transparent.

What Documents and Data are Required?

For a high-quality online oncology consultation, the specialist will need all your medical records:

• Medical reports describing your symptoms and the examinations performed
• Results of laboratory tests (complete blood count, biochemical profile, tumor markers, etc.)
• Histology report (biopsy results)
• CT, MRI, and PET-CT scans in DICOM format or as high-quality images
• Ultrasound and other imaging
• A description of any previous treatments (if applicable)

What is the Process?

On the MedicusUnion platform, the process is simple and clear for the patient:

Step1. Document Upload: You register for a personal account and upload all your available medical files and reports. Our coordinators help organize the information and, if necessary, arrange for translation into the required language.

Step 2. Physician Selection and Data Analysis: We match you with a specialist from a leading oncology clinic who focuses specifically on your type of cancer. The doctor thoroughly reviews all your documents and re-evaluates your radiological scans. In complex cases, a multidisciplinary team of related specialists—such as radiologists, pathologists, urologists, or surgical oncologists—may be involved.

Step 3. Video Consultation: At a scheduled time that you select during registration, you will have an online meeting with the doctor. They will discuss the diagnosis, answer your questions, and explain potential treatment options. The consultation is conducted with a professional medical interpreter to avoid any language barriers. You can ask all your questions and discuss the details.

Step 4. Written Report: Following the consultation, you will receive a detailed official report from the international expert in two languages (the original and a translation). This document will contain their professional opinion, confirming or revising the initial diagnosis, and providing a recommended treatment plan or suggestions for further diagnostic tests. You can share this medical report with your local doctor.

The Role of a Radiological Re-Evaluation

It's worth noting that a key component of an online oncology second opinion is the independent review of your CT, MRI, or PET-CT scans. An experienced radiologist from a major cancer center may notice details that were overlooked in the initial report, such as the precise tumor size, if there are metastases, or if adjacent organs are affected. In many cases, a re-evaluation leads to a revised diagnosis and, consequently, a completely different treatment plan.

What to Expect from an Online Second Opinion

The outcome of an online consultation is more than just a conversation. What exactly does the patient receive?

Confirmation or Adjustment of Your Diagnosis

In a significant number of cases, a second opinion confirms the initial diagnosis and treatment plan. This provides peace of mind and confidence that you are on the right track before starting therapy.

However, for many patients, a second opinion refutes or adjusts the original diagnosis. For example, a specialist might clarify the tumor type or stage of the disease, or identify additional factors that influence the treatment strategy and prognosis.

Alternative Treatment Options

Cancer treatment methods are constantly evolving. What was standard five years ago may have more effective alternatives today. Specialists at leading clinics are often the first to gain access to new protocols and clinical trials.

You will receive information on the most current treatment protocols used in top global clinics. This may include:

• Less invasive treatment methods with the same level of effectiveness
• Targeted therapy based on the tumor's molecular genetic profile, which specifically targets cancer cells
• Immunotherapy as an alternative or supplement to chemotherapy
• Participation in clinical trials for new drugs
• Organ-sparing surgeries instead of radical interventions

Prognosis and Recommendations

The expert will provide their assessment of the disease prognosis and create a specific, step-by-step action plan. This may include lifestyle and dietary recommendations during treatment, information on potential side effects and how to manage them, a follow-up monitoring plan, and advice on rehabilitation after completing the main course of treatment. With this document, you can return to your treating physician to discuss the proposed alternatives or, if you choose, continue treatment abroad.

The Benefits of an Online Second Opinion in Oncology

Online consultations offer several significant advantages over traditional in-person visits abroad.

Access to World-Class Cancer Centers

You no longer need to travel to get an opinion from a professor at Charité University Hospital (Berlin), Vienna General Hospital, or Hadassah Medical Center (Israel). Online consultation platforms like MedicusUnion provide access to doctors from leading clinics in Germany, Austria, and Israel—countries with the best cancer treatment outcomes in the world.

German oncology centers are known for their innovative approaches and strict quality standards. Israeli clinics are leaders in developing personalized treatment protocols. Austrian specialists combine high European standards with an individualized approach to each patient.

With a traditional approach, getting a consultation with such a specialist would involve long wait times and significant financial costs.

Speed and No Travel Required

In oncology, time is critical—every week of delay can be crucial. An online consultation can be arranged in just 3–7 days, whereas traveling abroad requires weeks of preparation.

By using this service, you avoid the need to apply for visas, book flights, find accommodation in a foreign country, endure the physical strain of travel (which is especially important if the patient's condition is fragile), and handle logistical issues like finding a local medical interpreter.

You can do this from the comfort of your home, with the full support of the platform's coordinators.

Significant Cost Savings

An online consultation is considerably more affordable than traveling abroad for an in-person visit. The average cost of an online second opinion is a few hundred euros, while a full trip abroad, including flights, accommodation, and consultations, can cost several thousand euros.

Yet, the quality of medical expertise remains at the same high level—you are being consulted by the same doctor who sees patients in the clinic.

When to Seek a Second Opinion in Oncology

Getting a second opinion from an oncologist is a good step at almost any stage. However, there are situations where it is especially important.

• If Cancer is Suspected. If the diagnosis is not yet final, but test results are concerning, a second opinion can help find out if these suspicions are reasonable and what additional tests are needed.
• Before Starting Chemotherapy or Radiation Therapy. These cancer treatments have a significant impact on your body. Before beginning, you should ensure that the optimal drugs have been selected for your tumor type, the dosages are calculated correctly, all alternatives have been considered, and the treatment plan aligns with modern international protocols.
• Rare Tumors. With rare forms of cancer, it is crucial to get an opinion from a specialist who has experience with that specific disease. An online consultation provides access to highly specialized experts from dedicated centers.
• If Complex or Extensive Surgery is Recommended. In such cases, a second opinion can help determine if the recommended scope of surgery is truly necessary or if there are less invasive options.
• If Treatment Isn't Working as Expected. If therapy fails to improve your condition or the disease is progressing, a second opinion may offer alternative approaches or adjustments to the current treatment plan.
• For Peace of Mind and Confidence. Even if there are no formal reasons to doubt the diagnosis, psychological comfort and confidence in your choices are a vital part of treatment. Having an independent expert confirm the diagnosis can give you the strength to move forward.
