Pediatric Brain Tumors: What You Need To Know

A diagnosis of a brain tumor in a child is one of the toughest moments any parent or caregiver will face. Between the medical decisions, emotional challenges, and questions about what comes next, it can be overwhelming. 

At The Preston Robert Tisch Brain Tumor Center, we believe that accurate, compassionate information empowers families. This guide aims to help you understand what pediatric brain tumors are, how they are detected and treated, the special considerations in children, and what support is available.

What Are Pediatric Brain Tumors?

Pediatric brain tumors are abnormal growths of cells in or around the brain or spinal cord in children. They can be benign (non-cancerous) or malignant (cancerous), fast-growing or slow-growing. Importantly, even non-malignant tumors in a child can cause serious problems, depending on their location, size, and how they affect developing brain structures.

Children’s brain anatomy, developmental stage, and biology differ from adults, which means tumors behave differently in kids. Also, treatment effects (surgery, radiation, chemotherapy) may have long-term consequences in children, on growth, cognition, and overall development.

Common Signs & Symptoms of Brain Tumors

Knowing what to watch for can lead to earlier diagnosis and better outcomes. Symptoms may vary depending on tumor size, type, and location. Some of the more common warning signs include:

  • Persistent headaches, often worse in the morning or awakening the child from sleep
  • Nausea and vomiting, especially upon waking or not tied to food intake
  • Vision changes, such as blurred, double vision, or a new impairment
  • Balance or coordination issues, including trouble walking, clumsiness, or unsteady gait
  • Seizures, even in children who have had no prior history
  • Behavioral or personality changes, mood swings, increased irritability, or confusion
  • Changes in school performance, memory, attention span, or cognitive skills

Because many childhood illnesses share symptoms like headaches or behavior changes, it’s important to consult a pediatrician or neuro-oncologist if symptoms persist or worsen.

How Pediatric Brain Tumors Are Classified

Understanding tumor classification helps guide decisions around treatment, prognosis, and expected challenges. Key classification features include:

  • Tumor Type (Histology): Determined via biopsy, this tells what kind of cell types are involved (e.g. gliomas, medulloblastomas, ependymomas, etc.).
  • Grade: Indicates how aggressive the tumor is: low grade (slower growth) versus high grade (rapid growth) and invasiveness.
  • Molecular & Genetic Features: Increasingly, pediatric brain tumors are classified by specific genetic or molecular markers (mutations, gene expression). These can guide targeted therapy.
  • Location: Where the tumor develops (cerebellum, brain stem, cerebral hemispheres, spinal cord) affects symptoms and treatment options, as well as risk of side effects.
  • Age & Developmental Stage of the Child: Younger children may have different treatment tolerances and long-term risks; developmental stage influences how aggressive treatments are used.

Diagnostic Process

When a brain tumor is suspected, a series of steps help confirm the diagnosis, assess extent, and plan treatment:

  • Medical History & Physical Examination - A pediatric neurologist or neuro-oncologist will review symptoms, history, and perform neurological exams (motor function, vision, reflexes, balance).
  • Imaging Studies - Imaging scans like MRI and CT scans play a key role in diagnostics. MRI is the standard imaging tool due to its detail and lack of radiation; sometimes MR spectroscopy or functional MRIs are used. In emergencies, CT scans may be done initially.
  • Lumbar Puncture (in some cases) - If there’s suspicion of cancer cells spreading into cerebrospinal fluid, or to help with certain tumor types.
  • Biopsy or Surgical Resection - Obtaining tissue is essential for determining tumor type, grade, and molecular markers. Sometimes surgery both diagnoses and treats by removing as much tumor as safely possible.
  • Molecular & Genetic Testing - Advanced testing of tumor tissue informs about specific mutations, which could open up targeted treatments or clinical trial options.

Treatment Options & Considerations

Treatment plans are tailored individually, balancing tumor features with the child’s age, health, and long-term quality of life. Common treatment modalities include:

Surgery

The first line for many tumors when safely operable. The goal is maximal safe resection,  removing as much tumor as possible without harming critical brain areas.

Radiation Therapy

Used either after surgery, for tumors that cannot be fully resected, or in specific aggressive types. In young children, care is taken with radiation for its potential long-term effects on brain development.

Chemotherapy

May be used in combination with surgery or radiation, or as an alternative when radiation must be delayed or minimized. Different regimens are chosen based on tumor type and molecular features.

Targeted Therapy & Immunotherapy

With advances in molecular biology, some tumors respond to therapies targeting specific genetic changes. Immunotherapy, leveraging the immune system, is a growing area of research.

Supportive & Rehabilitation Care

Because of the risk of impacts on cognition, motor skills, speech, and growth, rehabilitation (physical, occupational, speech therapy) is often part of the care plan. Attention is also paid to emotional, psychological, and neuropsychological support.

Special Challenges in Pediatric Patients

Children are not just small adults; their brains are developing, and side effects may be more significant in the long term. Some special considerations include:

  • Growth & Development: Treatments might affect physical growth, hormonal balance, or hearing and vision.
  • Cognitive and Educational Impact: Memory, attention, processing speed, reading, and learning may be affected. Long-term educational support is often needed.
  • Quality of Life: Beyond survival, preserving quality of life is critical, including managing fatigue, long-term neurological deficits, social/emotional development.
  • Family & Caregiver Burden: Decision-making, logistics, emotional stress, financial impact all weigh heavily.

Advances & Research Directions

Research is making pediatric brain tumor care better every year. Some promising areas include:

  • Precision Medicine: Using genomic sequencing of tumors to match patients with therapies most likely to work.
  • Less Harmful Radiation Approaches: Proton therapy, reduced doses, or delaying radiation when possible.
  • Novel Agents & Immunotherapies: New drugs targeting specific molecular pathways; immune checkpoint inhibitors; cell-based therapies.
  • Liquid Biopsies: Non-invasive blood or CSF tests to detect tumor DNA or signatures for earlier detection or monitoring.
  • Neurocognitive Rehabilitation: Better tools and programs to support children’s learning and development post-treatment.

Support & Resources at The Preston Robert Tisch Brain Tumor Center

At our Center, children and families receive holistic care, combining the best in clinical expertise and compassionate support:

  • Multidisciplinary teams (neuro-oncology, surgery, radiation oncology, supportive care, rehabilitation).
  • Access to clinical trials specific to pediatric brain tumors.
  • Neuropsychology, educational resources, speech/physical/occupational therapy.
  • Emotional, family, and caregiver support programs.
  • Transition planning for adolescents moving into adult care.

Pediatric brain tumors are complex, but not without hope. With earlier detection, newer therapies, improved surgical techniques, and enhanced support systems, many children not only survive but go on to live full lives. If your child has been diagnosed, or you suspect something, reach out. Our team of pediatric specialists are here to listen, guide, and partner with you every step of the way.
