What Does a Medical Oncologist Do? Understanding Your Cancer Specialist

A cancer diagnosis can bring many questions, and one of the first may be: What does a medical oncologist do? You may have heard the terms oncologist, medical oncologist, surgical oncologist or radiation oncologist, but understanding the difference can help you know which specialist is involved in your cancer care.

A medical oncologist is a doctor who specialises in the medical treatment and management of cancer. Depending on the type and stage of cancer, a medical oncologist may use treatments such as chemotherapy, targeted therapy, immunotherapy, hormonal therapy and other systemic cancer treatments. A medical oncologist may also coordinate care with surgeons, radiation oncologists and other specialists as part of a multidisciplinary cancer treatment plan.

For many patients, the medical oncologist plays an important role from the time cancer is diagnosed through treatment, follow-up and, when appropriate, long-term cancer care.

What Is Medical Oncology?

Medical oncology is the branch of oncology focused primarily on treating cancer with medicines and systemic therapies. These treatments can travel through the bloodstream and act throughout the body, which is particularly important when cancer may have spread beyond its original location.

Medical oncology includes several different types of cancer treatment, including chemotherapy, hormonal therapy, targeted therapy and immunotherapy. The treatment selected depends on factors such as the type of cancer, stage, pathology, molecular characteristics, previous treatments and the patient's overall health.

Modern medical oncology is increasingly personalised. Rather than assuming that every patient with the same cancer should receive exactly the same treatment, oncologists consider the biological characteristics of the cancer and the individual circumstances of the patient when developing a treatment plan.

What Does a Medical Oncologist Do?

The role of a medical oncologist extends beyond simply giving chemotherapy. A medical oncologist evaluates the cancer, determines appropriate treatment options, monitors response to treatment and helps manage treatment-related problems.

Some of the major responsibilities include:

1. Evaluating the Cancer Diagnosis

After cancer has been diagnosed, the medical oncologist reviews the available medical information to understand exactly what type of cancer the patient has.

This may include reviewing biopsy and pathology reports, imaging scans, blood tests, molecular or genetic test results and other clinical information.

The oncologist also considers the cancer's stage and other characteristics that can influence treatment decisions.

2. Understanding the Stage and Biology of Cancer

Cancer is not one single disease. Different cancers behave differently, and even two patients with the same cancer type may have different biological characteristics.

A medical oncologist considers factors such as:

• Cancer type and location
• Stage of cancer
• Histological or pathological features
• Molecular and genetic characteristics
• Biomarkers that may influence treatment
• Previous cancer treatments
• Overall health and other medical conditions
• The patient's goals and preferences

This information helps the oncology team determine which treatment approaches may be appropriate.

3. Developing a Personalised Cancer Treatment Plan

One of the most important responsibilities of a medical oncologist is developing an individualised treatment strategy.

Depending on the cancer, treatment may involve chemotherapy, immunotherapy, targeted therapy, hormonal therapy or combinations of different treatments.

In some situations, systemic treatment may be given before surgery or radiation therapy. This is known as neoadjuvant treatment. In other situations, treatment may be given after surgery to reduce the risk of recurrence, which is commonly referred to as adjuvant treatment.

For advanced cancer, systemic treatment may be used to control the disease, relieve symptoms and help maintain quality of life.

The exact approach depends on the individual patient's diagnosis and clinical circumstances.

4. Administering and Managing Chemotherapy

Chemotherapy remains an important treatment for many types of cancer.

Medical oncologists determine whether chemotherapy is appropriate, select the regimen when indicated, determine dosing and treatment schedules, and monitor patients during treatment.

They also assess how the cancer is responding and help manage possible side effects such as nausea, fatigue, changes in blood counts, infection risk, neuropathy and hair loss.

Cancer treatment is not simply about administering medicines. Careful monitoring and supportive treatment are important parts of the process.

5. Using Targeted Therapy

Targeted therapies are designed to act on specific molecular features involved in cancer growth or survival.

When a cancer has a particular biomarker or molecular alteration, targeted treatment may be considered if an appropriate therapy is available.

This is one reason molecular and biomarker testing can be important in selected cancers. ASCO notes that precision medicine can help identify treatments for patients whose tumors have specific characteristics that make them susceptible to particular therapies.

Targeted therapy does not mean that the treatment is automatically suitable for every patient. The relevance of a particular biomarker depends on the cancer type, clinical situation and available evidence.

6. Providing Immunotherapy

Immunotherapy uses medicines that help the immune system recognize or respond to cancer.

One important group is immune checkpoint inhibitors, which can block signals that cancer cells use to suppress immune activity. Immunotherapy is now an important treatment option for selected patients with several types of cancer.

However, immunotherapy is not appropriate for every cancer or every patient. The medical oncologist evaluates the cancer characteristics, available evidence and potential benefits and risks before recommending treatment.

7. Considering Hormonal Therapy

Some cancers depend on hormones for growth. Hormonal or endocrine therapy can therefore play an important role in treating certain cancers, particularly some breast and prostate cancers.

The medical oncologist determines whether hormonal treatment is appropriate based on the biology of the cancer and the patient's individual circumstances.

8. Monitoring Treatment Response

Cancer treatment does not end after the first dose of medicine.

A medical oncologist regularly evaluates whether treatment is working and whether the patient is tolerating it appropriately.

Monitoring may involve:

• Physical examinations
• Blood tests
• Tumor markers in selected situations
• CT, MRI, PET or other imaging when clinically appropriate
• Pathology or molecular assessments in selected cases
• Assessment of symptoms and quality of life

Based on the results, treatment may be continued, modified, paused or changed.

9. Managing Cancer Treatment Side Effects

Managing side effects is an important part of medical oncology.

Different cancer treatments can cause different side effects. Depending on the treatment, patients may experience fatigue, nausea, vomiting, reduced blood counts, neuropathy, skin changes, appetite changes or hair loss.

A medical oncologist and the oncology care team can prescribe supportive medicines and recommend appropriate measures to reduce or manage these problems.

The goal is not only to treat the cancer but also to help patients remain as comfortable, functional and supported as possible during treatment.

10. Coordinating With Other Cancer Specialists

Cancer treatment is often multidisciplinary.

Depending on the diagnosis, a patient's treatment team may include a medical oncologist, surgical oncologist, radiation oncologist, pathologist, radiologist, specialist nurses, pharmacist, nutrition professional, physiotherapist and other healthcare professionals.

For example, a patient may undergo surgery followed by systemic treatment and radiation therapy. The medical oncologist may coordinate the systemic component of treatment while working with the other specialists.

The National Cancer Institute describes cancer care as a team effort involving multiple healthcare professionals who work together to provide comprehensive care.

What Is the Difference Between a Medical Oncologist and a Surgical Oncologist?

The simplest distinction is the type of treatment each specialist primarily provides.

A medical oncologist primarily manages cancer using medicines such as chemotherapy, targeted therapy, immunotherapy and hormonal therapy.

A surgical oncologist specialises in the surgical treatment of cancer and performs operations to remove tumors or manage cancer-related conditions.

These specialists often work together. Surgery may remove a localized tumor, while systemic treatment may be recommended before or after surgery depending on the cancer.

What Is the Difference Between a Medical Oncologist and a Radiation Oncologist?

A radiation oncologist specialises in treating cancer with radiation therapy.

A medical oncologist primarily uses systemic cancer treatments such as chemotherapy, targeted therapy, immunotherapy and hormonal therapy.

For some patients, these treatments are combined. The sequence and combination depend on the cancer type, stage and individual treatment plan.

When Should You See a Medical Oncologist?

You may be referred to a medical oncologist after a cancer diagnosis, particularly when systemic treatment may be required.

A consultation may also be appropriate when:

• A biopsy has confirmed cancer.
• Imaging suggests cancer that requires specialist evaluation.
• Surgery has been recommended and additional systemic treatment may be needed.
• Cancer has returned after previous treatment.
• Cancer has spread to other parts of the body.
• Molecular or biomarker testing may help guide treatment.
• You want a specialist opinion about available treatment options.

If you have recently received a cancer diagnosis, discussing your pathology, imaging and treatment options with an appropriate oncology specialist can help you understand the next steps.

What Happens During a Medical Oncology Consultation?

Your first consultation may involve a detailed review of your medical history and cancer-related reports.

The medical oncologist may discuss:

1. Your cancer diagnosis and pathology.
2. The stage and characteristics of the cancer.
3. Whether additional investigations are required.
4. Available treatment approaches.
5. The potential benefits and risks of treatment.
6. Possible treatment side effects.
7. The expected treatment schedule.
8. Follow-up and monitoring.

It can be helpful to bring pathology reports, imaging reports and discs when applicable, previous treatment records and a list of current medicines to your appointment.

Patients should also feel comfortable asking questions. Clear communication between patients and their cancer care team is an important part of cancer care.

Does Every Cancer Patient Need Chemotherapy?

No.

Chemotherapy is only one type of cancer treatment, and not every patient requires it.

Depending on the cancer, treatment may involve surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, hormonal therapy, active surveillance or combinations of these approaches.

The appropriate treatment depends on the cancer type, stage, biological characteristics, previous treatments and the individual patient's situation.

This is why cancer treatment should be individualized rather than based simply on the experience of another patient with a similar diagnosis.

How Medical Oncology Is Becoming More Personalised

Cancer treatment has increasingly moved toward a more personalized approach.

Modern oncology may incorporate pathology, imaging, biomarkers, genetic testing and molecular profiling to better understand an individual cancer.

For selected patients, molecular testing can identify alterations that may have treatment implications. Similarly, biomarkers can sometimes help determine whether a patient may be more likely to benefit from a particular treatment.

However, testing is not automatically necessary for every patient or every cancer. A medical oncologist can determine whether a particular test is clinically relevant.
