Facing a cancer diagnosis can be overwhelming, and one of the first steps is understanding the medical professionals who will be by your side. Oncologists are specialists who play a pivotal role in cancer care, but what exactly do they do?

Key takeaways

  • Oncologists are doctors who specialize in diagnosing and treating cancer
  • There are three main types: medical, surgical, and radiation oncologists
  • They collaborate within multidisciplinary teams to provide comprehensive care

    What does an oncologist do?

    An oncologist is a medical doctor dedicated to diagnosing, treating, and managing cancer. They play a central role in a patient's cancer journey, from initial diagnosis to post-treatment care. But what exactly does that entail?

    Role and responsibilities

    Oncologists are at the forefront of cancer care. They:

    • Diagnose cancer: Using various tests and procedures to determine the presence and extent of cancer.
    • Explain the diagnosis and staging: Helping patients understand their condition and its implications for their health.
    • Develop treatment plans: Outlining the best course of action, which may include surgery, chemotherapy, radiation, or a combination.
    • Oversee treatment: Monitoring progress and making adjustments as necessary.
    • Manage symptoms and side effects: Providing support to alleviate discomfort from both the disease and its treatment, ensuring the patient's quality of life is maintained.

    Types of oncologists

    Cancer treatment is multifaceted, and different oncologists specialize in specific treatment methods.

    Medical oncologists

    Medical oncologists treat cancer using medications like chemotherapy, hormone therapy, immunotherapy, and targeted therapy. They often serve as the primary healthcare provider for cancer patients, coordinating with other specialists and offering supportive care throughout treatment.

    They are experts in using medications to attack cancer cells, including the latest advances in immunotherapy, which harnesses the patient's own immune system, and targeted therapy, which focuses on specific molecules involved in cancer growth.

    Surgical oncologists

    Surgical oncologists focus on the surgical removal of tumors and surrounding tissues. They also perform biopsies to diagnose cancer. Their expertise is crucial when surgery is part of the treatment plan, whether it’s to remove the entire tumor or to reduce its size before other treatments can be administered.

    Radiation oncologists

    Radiation oncologists use high-energy radiation to destroy cancer cells. They design and oversee radiation therapy treatments, ensuring precise targeting to minimize damage to healthy tissues. Advanced techniques allow them to focus radiation more accurately, improving outcomes and reducing side effects.

    Specialized oncology areas

    Beyond the primary types, some oncologists specialize further to focus on specific cancers or patient groups:

    • Hematologist oncologists: Experts in blood cancers like leukemia, lymphoma, and myeloma.
    • Gynecologic oncologists: Specialize in cancers of the female reproductive system.
    • Pediatric oncologists: Focus on cancers affecting children and teenagers.
    • Geriatric oncologists: Address the unique challenges of treating older adults with cancer.
    • Neuro-oncologists: Treat cancers of the brain, spinal cord, and nervous system.
    • Thoracic oncologists: Specialize in cancers of the chest area, including the lungs and esophagus.
    • Urologic oncologists: Focus on cancers in the genitourinary system, like the bladder and kidneys.

    Specialization allows oncologists to gain deeper insights into specific cancer types, providing patients with the most effective and cutting-edge treatments. For example, a pediatric oncologist understands the unique needs of children, whose cancers often differ from adults both biologically and in their response to treatment.

    VitaRx Tip

    Did you know the term "oncology" comes from the Greek word "onkos," meaning mass or tumor, combined with "logy," meaning study of. So, oncology literally means the study of tumors!

    Training and certification

    Becoming an oncologist requires extensive education and training:

    • Medical degree: Complete medical school to become a doctor.
    • Residency: Undertake residency training in internal medicine or general surgery.
    • Fellowship: Specialize further with a fellowship in oncology, which can take an additional 2-3 years.
    • Board certification: Obtain board certification in their oncology specialty.

    Many participate in continuing medical education and may be involved in clinical trials and research.

    Always stay informed

    Oncology is a rapidly evolving field, and oncologists must stay up-to-date with the latest advancements and research to provide the best care.

    In countries like Australia, oncologists are members of professional organizations, like:

    • FRACP: Fellow of the Royal Australasian College of Physicians for medical oncologists.
    • FRACS: Fellow of the Royal Australasian College of Surgeons for surgical oncologists.
    • FRANZCR: Fellow of the Royal Australian and New Zealand College of Radiologists for radiation oncologists.

    When should you see an oncologist?

    Typically, your primary care physician or specialist will refer you to an oncologist if:

    • You have a cancer diagnosis: To begin specialized treatment.
    • Cancer is suspected: Due to symptoms or test results.
    • High-risk factors: Such as a strong family history or exposure to carcinogens.

    Oncologists also play a role in:

    • Follow-up care: Monitoring after treatment completion to check for recurrence.
    • Palliative care: Managing symptoms and improving quality of life in advanced cancer.
