What Is a Neuro-Oncologist & What Do They Do?

A neuro-oncologist is a specialized medical doctor who diagnoses and treats cancers affecting the nervous system, including tumors of the brain, spinal cord, and peripheral nerves. These physicians combine expertise from neurology and oncology to provide comprehensive care for individuals with these complex conditions. Their objective is to manage the disease while preserving neurological function.

Role and Scope of Practice

Neuro-oncologists diagnose and manage tumors originating in the brain or spinal cord (primary tumors), such as glioblastomas, gliomas (astrocytomas, oligodendrogliomas), and meningiomas. They also treat metastatic cancers that have spread to the nervous system from other body parts. Their scope includes primary central nervous system lymphomas and other less common nervous system tumors.

Neuro-oncologists use diverse treatment approaches tailored to each patient’s tumor type. They utilize medical therapies such as chemotherapy, targeted therapies, and immunotherapy, which harnesses the body’s immune system. These interventions are often combined with radiation therapy.

Beyond direct tumor treatment, neuro-oncologists manage symptoms caused by the tumor or its therapies. This includes addressing neurological complications like seizures, headaches, and cognitive changes to improve patient comfort and daily functioning. Their care plan emphasizes preserving neurological function and enhancing overall quality of life.

Training and Specialization

Becoming a neuro-oncologist requires specialized medical training. Training begins with medical school. Following this, physicians undergo a residency program, typically in neurology or internal medicine with an oncology focus, providing a foundation in nervous system disorders or cancer.

After residency, aspiring neuro-oncologists complete a specialized neuro-oncology fellowship, typically lasting one to two years. This fellowship provides training in diagnosing and managing brain and spinal cord tumors. They gain knowledge of nervous system cancer challenges, including their biology and impact on neurological function. This training leads to board certification, signifying expertise in both neurology and oncology for nervous system cancers.

When to Consult a Neuro-Oncologist

A referral to a neuro-oncologist is considered with a suspected or confirmed diagnosis of a tumor affecting the brain, spinal cord, or peripheral nerves. This includes individuals newly diagnosed with primary brain or spinal cord tumors, or those whose cancer has spread to the nervous system from elsewhere. Patients previously treated for nervous system cancers who experience a recurrence also commonly consult a neuro-oncologist.

Certain neurological symptoms can indicate the need for evaluation by a neuro-oncologist. These symptoms arise from the tumor’s pressure on or infiltration of nervous system structures. Examples include:
Persistent or worsening headaches
Unexplained seizures
Changes in vision
Difficulties with speech or understanding
New weakness or numbness in limbs
Problems with balance or coordination
Noticeable changes in memory, personality, or behavior

A physician will often order imaging studies, such as an MRI, if these symptoms suggest a potential nervous system mass, which can then lead to a neuro-oncology consultation.

The Collaborative Care Team

Neuro-oncologists are members of a larger, multidisciplinary healthcare team, recognizing that comprehensive cancer care requires diverse expertise. They work closely with neurosurgeons, who perform surgical removal of brain and spinal cord tumors. Radiation oncologists are also collaborators, delivering targeted radiation therapy to destroy cancer cells or prevent recurrence.

Collaboration extends to:
Medical oncologists, who manage systemic cancer treatments.
Neurologists, who address general neurological issues.
Neuropathologists, who analyze tissue samples to diagnose tumor type and grade.
Radiologists, who interpret imaging studies for tumor location and characteristics.

Supportive care professionals like physical therapists, occupational therapists, and social workers also help manage symptoms and support patient well-being. This collaborative model ensures individualized and well-coordinated care throughout the treatment journey.
