Oncologist Online — Consultation and Second Opinion

Oncologist Online—Consultation and Second Opinion

A cancer diagnosis, or even the suspicion of one, can feel overwhelming. You ask yourself hundreds of questions: Could there be a mistake? What should I do next? Where do I find help? Am I running out of time? It feels like you need to decide right here and now.

An oncologist online on the MedicusUnion platform gives you access to practicing oncologists at leading clinics in Germany, Austria, and Switzerland—from your home, with no flights or visas required. An online oncologist consultation is right for you whether you've just noticed worrying symptoms or already have a diagnosis in hand but need confidence that the chosen treatment path is the right one.

We work in two formats. The first is an initial video consultation: the doctor reviews your test results and imaging, answers your questions, and outlines a plan for further workup. The second is a second opinion in oncology: an independent expert re-evaluates your diagnosis and test results, then provides a detailed assessment of your treatment strategy.

Below, we explain in detail how to get a second opinion from an oncologist, how the consultation works, what documents you need to prepare, which diagnoses and situations we help with, who exactly will be consulting you, how much an online oncologist consultation costs, and what to do if you need in-person treatment abroad after your consultation.

What Is a Second Opinion in Oncology, and Why Do You Need One?

In short, it's an independent assessment of your diagnosis and treatment plan by another oncologist. In practice, here's how it works: you send your medical records—discharge reports, biopsy results, CT, MRI, and PET-CT scans—to an independent specialist who was not involved in your original diagnosis or treatment decisions. The doctor reviews the materials, conducts a video consultation if needed, and issues a comprehensive written opinion that confirms or questions the diagnosis, clarifies the stage, suggests an alternative strategy, or adjusts the treatment plan.

The numbers show this is not a formality. According to a study published in JCO Oncology Practice, 23–57% of patients diagnosed with lung cancer, head and neck cancer, colorectal cancer, or myeloma (a form of blood cancer) had their treatment plan significantly changed after getting a second opinion in oncology. In some cases, this meant avoiding an overly aggressive intervention. In others, it meant accessing a treatment that had not originally been considered.

Many patients hesitate to seek a second opinion, worried they'll offend their treating physician or appear distrustful. In reality, a second opinion is not a distrust—it's a vital part of high-quality cancer care. At leading clinics in Germany, Austria, and Switzerland, every serious diagnosis is reviewed by a multidisciplinary tumor board—a group of specialists who discuss the case together.

When You Need an Online Oncologist Consultation

A consultation with an international specialist is often the first step toward arranging treatment at one of the world's leading clinics. The doctor can recommend a specific clinic and treatment method, and even coordinate directly with colleagues on-site.

When is seeing an oncologist online the optimal choice?

Online Oncologist Consultation or In-Person Clinic Visit: Which to Choose?

This isn't a choice between a good option and a bad one — the two complement each other. An online consultation covers most of what you need at the stage of understanding your diagnosis and defining a plan. If further diagnostic workup or treatment abroad turns out to be necessary, MedicusUnion handles the medical travel arrangements.

What to Do If You Need Treatment Abroad After Your Consultation?

If it becomes clear after consultation that in-person treatment abroad is the optimal choice, MedicusUnion will help you select a clinic, assist with organizational matters, and support you at every stage of your trip.

Important: only you decide whether to travel. After your consultation, you receive a written opinion and recommendations, and you decide whether to continue treatment at a foreign clinic or be monitored at home.

How to Get a Second Opinion from an Oncologist at MedicusUnion

We’ve built a process that is as simple and transparent as possible, and you can get a second opinion in oncology right from the comfort of your home. Your path consists of a few clear steps:

1. Submitting a Request and Gathering Medical Records

You upload all the medical documents you already have on hand: pathology reports, imaging (CT, MRI, PET-CT), discharge reports, and lab results, and submit a request.

2. Translating and Preparing Documents

If your documents are in a language the doctor doesn’t speak, the MedicusUnion team handles the professional medical translation into the language they speak (typically German or English).

3. Matching You with a Specialized Oncologist Online

We do not send requests to just any available doctor. Your personal coordinator selects an expert who specializes specifically in your type of cancer and has extensive experience treating similar cases.

4. Case Review by the Doctor

An international oncologist online thoroughly reviews your medical history, imaging, and protocols within 3–5 business days.

5. Video Consultation or Written Report

Next, depending on the format you choose, you get:

• Video consultation: A real-time appointment with the doctor via video. The doctor explains their findings in detail, breaks down the treatment strategy, and answers all your questions. If needed, a medical interpreter joins the online oncologist consultation to ensure full and seamless communication with the doctor.
• Written report: A comprehensive document containing an evaluation of your diagnosis, recommendations for further workup, and a treatment plan in German or English, accompanied by a certified translation into your language if needed.

If you choose the video consultation format, the doctor will also provide a detailed written report with the diagnosis and recommendations.

The main advantage of this format: You do not need to plan a complicated trip, purchase tickets, or worry about visas. A high-quality second opinion in oncology is available from the comfort of your home, saving you time, effort, and money.

Diagnoses and Situations We Can Help With

Online oncologists on the MedicusUnion platform work with a wide range of cancer diagnoses. We already provide support in the areas listed below, and we've put together detailed, practical resources on each one. If your situation isn't on the list, reach out to our coordinator—we will make sure to find the right specialist for you. 

Suspected Cancer: What to Do Right at the Start

When test results are concerning but a diagnosis hasn't been confirmed yet, it's important not to waste precious time, but also not to jump to conclusions. We walk through which steps to take first and how to avoid common mistakes at this stage.

Read our detailed step-by-step guide for early symptoms and conflicting test results here: Suspected Cancer: Second Opinion and Treatment Abroad.

Lung Cancer: Second Opinion and Treatment Strategy

In lung cancer, the treatment choice depends on the tumor type, location, disease stage, molecular and genetic profile, and the patient's overall condition. A second opinion in oncology from a thoracic oncologist helps evaluate the proposed treatment strategy, the need for surgery, systemic therapy, or radiation treatment.

Learn more about the nuances of choosing protocols and the role of thoracic oncologists in our article: [Second Opinion for Lung Cancer].

Gastrointestinal Cancers

Treating the digestive system tumors lies at the intersection of oncology, gastroenterology, and abdominal surgery. An online oncologist consultation allows you to compare endoscopy findings, pathology results, and imaging studies to assess whether radical surgery is required or whether the chemotherapy protocol needs adjustment.

A detailed breakdown of treatment strategies for digestive tract tumors is available in our article: [Second Opinion for Gastrointestinal Cancers].

CAR-T and Innovative Cell Therapy

Immunotherapy and CAR-T cell therapy are cutting-edge treatment methods that train the immune system's cells to recognize and destroy tumors. They are typically used when traditional methods didn’t prove to be effective. An oncologist online can help determine if this method is right for your specific situation and which medical centers offer this treatment.

Learn more in our guide: [CAR-T Therapy: When a Second Opinion Is Essential].

Psycho-Oncology Support

A patient's emotional well-being—and that of their family—directly impacts treatment outcomes. Working with a specialized psycho-oncologist isn't a sign of weakness; it's an important part of comprehensive care that helps patients cope with fear and anxiety. This support benefits not just the patient, but their family as well, throughout every stage of treatment.

Read about how psychological support affects treatment outcomes in our article: [Online Psycho-Oncologist: Support for Patients and Families].

Rehabilitation After Treatment

After surgery, chemotherapy, or radiation therapy, the body needs a well-structured rehabilitation plan to restore organ function and return to a normal rhythm of life. We help build a rehabilitation program tailored to the specific treatment you’ve received.

Learn more about rehabilitation methods in our article: [Rehabilitation After Cancer Treatment].

Who Conducts the Consultations — Our Doctors and Clinics

At MedicusUnion, consultations aren't handled by just any oncologist—they're conducted by practicing specialists from leading international and university clinics. We don't connect you with the first available doctor; instead, we match you individually with a specialist based on your tumor location, disease stage, test results, and the goal of your request. For example, if you're dealing with lung cancer, your consultation will be led by a thoracic oncologist rather than a general oncologist.

We work with doctors from leading clinics in Germany, Austria, Switzerland, and other countries who follow current international protocols and have extensive experience managing complex clinical cases.

Professor Mutlu Demiray is an innovative oncologist with over 20 years of experience, recognized for his pioneering approach to personalized treatment using molecular and genetic profiling. He has developed protocols for precision oncology and has participated in international clinical trials in immunotherapy. He regularly lectures on targeted therapy and translational oncology.

Professor Ofer Spilberg is a member of the Israeli Hemato-Oncology Association and the author of more than 70 scientific publications. He teaches at the Tel Aviv University Medical School and also at the medical center affiliated with the University of Pittsburgh.

Professor Irene Kührer brings 33 years of experience. She is a leading physician at the University Clinic of the General Hospital of Vienna (AKH, Austria) and a recognized expert in the diagnosis and treatment of breast cancer as well as other oncological diseases.

Beyond breast cancer, Dr. Kührer treats a wide range of cancer cases—including stomach, intestines, liver, brain, skin, and reproductive system tumors.

She chairs the Oncology Board of the University Clinic of Vienna and is a co-founder of the EFR (European Federation for Colorectal Cancer), a pan-European platform dedicated to improving treatment methods for colorectal cancer.

Transparency is another core principle at MedicusUnion. You know upfront what exactly you get and how much it costs, with no hidden fees.

All medical reports are prepared to international standards with official translation. You can share and discuss this report with your doctor back home.

For guidance on how to present a medical opinion from abroad to your doctor and build a constructive dialogue, see our guide [How to Discuss a Foreign Medical Report With Your Doctor].

How Much Does an Online Oncologist Consultation Cost?

The cost of a consultation with a specific specialist is listed on their profile page on our website and depends on the expert’s status and qualifications. For example, a consultation with a department head or an internationally recognized professor may cost more.

The final price also depends on additional factors:

• Consultation format: A live video consultation, a detailed written second opinion in oncology, or a combination of the two.
• Translation needs: How many documents require certified translation, or whether you need an interpreter during the video consultation.

If you'd like to find out how much a consultation would cost in your specific case, submit a request on our website. A coordinator will confirm the details and give you a price within one business day. This is free and comes with no obligation.

Frequently Asked Questions

• Can I Trust a Diagnosis Made Online?

An online oncologist doesn't make a diagnosis from scratch based on a description of symptoms. The doctor doesn't work blind—they review your records, pathology results, CT, MRI, and PET-CT scans, and discharge summaries in advance, and only then provide a medical opinion.

• What If the Doctor’s Opinion Differs from My Treating Physician’s?

Different recommendations don't mean one of the doctors is wrong. In oncology, several treatment options can often be possible, depending on the specialist’s experience, available technology, and international clinical protocols. Once you have a second opinion, you can discuss it with your treating physician and make an informed decision.

• How Secure Is My Information?

Data security is an absolute priority for us. MedicusUnion strictly complies with the European General Data Protection Regulation (GDPR). All medical records, discharge reports, and digital imaging are transmitted through a secure platform over encrypted channels and can be accessed only by your coordinator and assigned specialist.

• Do I Need to Speak a Foreign Language for the Consultation?

No, knowing a foreign language isn't required. The MedicusUnion team handles certified translation of all your medical documentation. A qualified medical interpreter also joins your video consultation, and you'll receive the final written report in the clinic's language along with a translation into your language.

• How Quickly Can I Get a Consultation?

On average, preparing for and completing a consultation takes 3 to 5 business days from the moment you upload your full set of documents. This time is necessary for high-quality translation and a thorough review by the international expert.

• Is the Online Format Suitable for Urgent or Emergency Cases?

If you have acute symptoms—bleeding, high fever, severe pain—seek emergency care locally first. However, if you need to decide about chemotherapy or a planned surgery, an online oncologist consultation can give you an authoritative opinion within days. It will help you avoid a costly mistake.

• How Do I Get a Second Opinion from an Oncologist if I've Already Started Treatment?

Yes, this is one of the most common situations we see. Patients seek a second opinion from an oncologist during treatment, either to confirm that the chosen approach is correct or to learn about alternative methods that might be more effective. The doctor will review your medical history, assess how your condition has progressed, and advise whether to continue your current treatment, adjust it, or consider other options.
