Brain Tumor Diagnosis in Beverly Hills: What Patients and Families Should Know

Few phrases carry the emotional weight of "brain tumor." Whether you've just received this diagnosis yourself or you're supporting a family member or loved one who has, the combination of fear, uncertainty, and urgency can feel completely paralyzing. Questions flood in: Is it cancer? Does it need surgery? How fast do we need to act? What does the future look like?

Dr. Albert P. Wong is a neurosurgeon in Beverly Hills who works closely with patients and families navigating this difficult journey - and one of the most important things he communicates from the very first consultation is this: a brain tumor diagnosis is the beginning of a process, not the end of a story. With the right information, the right team, and a clear treatment plan, many patients go on to live full and meaningful lives after diagnosis. Understanding what lies ahead can help you begin to regain a sense of agency and control.

Not All Brain Tumors Are the Same

This is arguably the most important point to understand from the outset: "brain tumor" is not a single diagnosis. It is an umbrella term that covers dozens of distinct conditions, each with different characteristics, behaviors, treatment approaches, and prognoses. The specifics of your tumor - its type, grade, size, and location - will determine virtually everything about what happens next.

Benign vs. Malignant Benign brain tumors do not contain cancer cells and typically grow slowly. They do not invade surrounding brain tissue and do not spread to other parts of the body. However, even benign tumors can cause serious, life-altering problems depending on where they are located and how large they become - a benign tumor pressing on the brainstem or an optic nerve, for example, can be every bit as dangerous as a malignant one.

Malignant brain tumors are cancerous. They grow more rapidly, tend to invade surrounding brain tissue, and may spread through the cerebrospinal fluid. They generally require more aggressive treatment including surgery, radiation, and chemotherapy.

Primary vs. Metastatic Primary brain tumors originate in the brain or its surrounding structures. They can arise from brain cells (gliomas), the meninges (meningiomas), the pituitary gland, or the nerves entering the brain.

Metastatic brain tumors originate from cancer elsewhere in the body - most commonly the lungs, breast, colon, kidney, or skin - and travel to the brain through the bloodstream. Metastatic tumors in the brain are actually more common than primary brain tumors.

Grade Brain tumors are classified on a scale from Grade I to Grade IV based on how abnormal the cells appear under a microscope and how rapidly they are likely to grow. Grade I and II tumors are generally slow-growing and less aggressive. Grade III and IV tumors are faster-growing and require more urgent and intensive treatment.

Common Types of Brain Tumors

Glioblastoma (GBM) Glioblastoma is a Grade IV glioma and the most aggressive primary brain tumor. It arises from astrocytes - star-shaped brain cells - and grows rapidly, often infiltrating surrounding brain tissue. Treatment typically involves surgical resection, followed by concurrent radiation and chemotherapy. Despite treatment, the recurrence rate is high, and ongoing research into new therapies is a significant area of clinical focus.

Meningioma Meningiomas arise from the meninges - the protective membranes surrounding the brain and spinal cord. They are the most common primary brain tumor overall and are benign in the vast majority of cases. Many grow slowly enough that observation with periodic MRI imaging is appropriate rather than immediate surgery. When treatment is needed, surgical removal is often curative.

Acoustic Neuroma (Vestibular Schwannoma) This is a benign tumor that grows on the vestibular nerve - the nerve connecting the inner ear to the brain. It typically causes progressive hearing loss, tinnitus (ringing in the ear), and balance problems. Treatment options include observation, radiosurgery, or microsurgical removal depending on size and symptom severity.

Pituitary Adenoma These tumors arise from the pituitary gland at the base of the brain. They can be functioning (producing excess hormones) or non-functioning, and they vary widely in size. Large pituitary adenomas can compress the optic nerves and cause vision problems. They are often treated with minimally invasive endoscopic surgery through the nose, avoiding any external incisions.

Diagnosis: The Tests You Will Need

The diagnostic process for a suspected brain tumor typically begins when a patient presents with new symptoms - persistent or progressively worsening headaches, new seizures, changes in vision, cognitive changes, personality changes, or focal neurological symptoms such as weakness on one side of the body.

MRI with contrast - The gold standard imaging modality for brain tumor evaluation. Contrast-enhanced MRI provides detailed images of the tumor's location, size, borders, and relationship to surrounding structures.
CT scan - Often the first imaging obtained in emergency settings due to its speed and availability. Less detailed than MRI but useful for identifying large masses, bleeding, or swelling.
PET scan - Used to assess the metabolic activity of a tumor, helping distinguish between high-grade and low-grade lesions and between tumor recurrence and treatment-related changes.
Functional MRI (fMRI) - Maps important brain functions such as language and motor control to determine how close the tumor is to these critical areas - essential for surgical planning.
Biopsy - A tissue sample, obtained either during open surgery or through a stereotactic needle procedure, provides a definitive pathological diagnosis and guides all subsequent treatment decisions.

Treatment Options for Brain Tumors

Treatment is not one-size-fits-all. The approach depends on the tumor's type, grade, and location; the patient's age and overall health; the presence or absence of neurological symptoms; and the patient's personal goals and values.

Surgery (Craniotomy) For many brain tumors, surgical resection - removing as much of the tumor as safely possible - is the first and most important step. Modern neurosurgical techniques have transformed the safety and precision of brain surgery. Advances including neuronavigation systems, robotic-assisted approaches, intraoperative MRI, fluorescence-guided surgery, and awake craniotomy (where the patient remains conscious during parts of the procedure to allow real-time monitoring of language and motor function) have dramatically expanded what surgeons can safely accomplish.

Radiation Therapy Radiation is commonly used after surgery to target any remaining tumor cells. For some patients, stereotactic radiosurgery - delivered by systems such as Gamma Knife or CyberKnife - delivers a highly focused, high-dose radiation treatment to the tumor in one or a few sessions, with minimal effect on surrounding brain tissue.

Chemotherapy Chemotherapy is used in conjunction with surgery and radiation for malignant tumors, particularly glioblastoma. Temozolomide is the most commonly used chemotherapy agent for GBM, often administered concurrently with radiation and then continued for several months afterward.

Observation (Active Monitoring) For small, slow-growing benign tumors - particularly in older patients or those with minimal symptoms - close monitoring with periodic MRI scans may be the most appropriate initial approach. The goal is to intervene before symptoms become significant while avoiding unnecessary treatment.

Building Your Care Team

Brain tumor care is a team effort. As your neurosurgeon, Dr. Wong's role is to evaluate the surgical risk and potential benefit, perform any necessary procedure with the highest level of technical precision, and remain an accessible and consistent resource throughout your care journey - before surgery, immediately afterward, and during long-term follow-up.

But the neurosurgeon is one part of a larger team that typically includes a neuro-oncologist, a radiation oncologist, a neuropsychologist to assess and monitor cognitive function, a social worker to assist with practical and emotional support, and rehabilitation specialists to help restore any functions affected by the tumor or its treatment.
