Brain Tumors

Brain tumors are abnormal growths of cells within the brain or the central spinal canal. They can be primary (originating in the brain) or metastatic (spreading from cancers elsewhere in the body). Primary brain tumors develop from brain cells, supportive tissue cells, or the brain's blood vessels. They vary widely in aggressiveness, from slow-growing benign tumors to rapidly growing malignant ones. The location of a brain tumor is often more critical than whether it's benign or malignant, as even benign tumors can be life-threatening if they compress vital brain structures. Brain tumors affect people of all ages, from children to older adults, though specific types are more common in certain age groups. Advances in diagnostic techniques, surgical approaches, radiation delivery methods, and targeted therapies have significantly improved outcomes for many patients with brain tumors.

What Causes It?

Genetic factors - Certain inherited conditions increase risk, including neurofibromatosis, tuberous sclerosis, Li-Fraumeni syndrome, von Hippel-Lindau disease, and retinoblastoma

Prior radiation exposure - Therapeutic radiation to the head for other conditions increases risk of later developing brain tumors

Immune system disorders - People with compromised immune systems have higher risk of central nervous system lymphoma

Age - Some tumor types are more common in specific age groups (e.g., medulloblastomas in children, meningiomas in older adults)

Family history - Having a first-degree relative with a brain tumor slightly increases risk

Exposure to certain chemicals - Some industrial chemicals, pesticides, and solvents have been associated with increased risk in some studies

Viral infections - Certain viruses, like Epstein-Barr virus, may increase risk of specific types of brain lymphoma

Race and ethnicity - Some tumor types show variations in incidence by race and ethnicity

For most primary brain tumors, the exact cause remains unknown

Metastatic brain tumors originate from primary cancers elsewhere in the body, commonly lung, breast, skin (melanoma), kidney, and colorectal cancers

Signs & Symptoms

Headaches - Often worse in the morning or that awaken you from sleep, may become more frequent and severe over time

Seizures - Especially in adults with no history of seizures

Cognitive changes - Problems with memory, thinking, concentration, or behavior

Personality changes - Mood swings, irritability, or abnormal behavior

Nausea and vomiting - Particularly in the morning or unrelated to other causes

Vision problems - Blurred vision, double vision, or partial or complete loss of vision

Speech difficulties - Problems finding words or speaking clearly

Balance problems - Dizziness, trouble walking, or lack of coordination

Weakness or numbness - Often on one side of the body or in specific limbs

Hearing problems - Ringing in ears (tinnitus) or gradual hearing loss

Symptoms vary widely depending on tumor location, size, and growth rate

Symptoms may develop gradually or appear suddenly

Some small or slow-growing tumors may not cause any symptoms initially

How We Diagnose

Our specialists use advanced diagnostic methods to accurately identify and assess your condition

Neurological Examination

A comprehensive assessment of brain function, including testing of reflexes, muscle strength, eye and mouth movement, coordination, balance, alertness, and other cognitive abilities. This helps identify which areas of the brain might be affected and guides subsequent diagnostic testing.

Advanced Imaging

Magnetic resonance imaging (MRI) with contrast is the gold standard for brain tumor detection, providing detailed images of brain structures and abnormalities. Functional MRI (fMRI) shows brain activity in relation to specific functions. Magnetic resonance spectroscopy (MRS) analyzes chemical composition of brain tissue. Diffusion tensor imaging (DTI) maps white matter tracts. Computed tomography (CT) scans may be used initially or when MRI is contraindicated. Positron emission tomography (PET) helps distinguish between tumor recurrence and radiation necrosis and may guide biopsy.

Biopsy

The definitive method for determining tumor type involves removing a sample of tumor tissue for examination by a neuropathologist. This may be performed as part of tumor removal surgery (resection) or as a separate procedure when complete removal isn't initially possible. Stereotactic biopsy uses precise 3D coordinates to target specific areas with minimal invasiveness. Advanced molecular and genetic testing of the sample helps classify the tumor and may guide treatment decisions.

Cerebrospinal Fluid Analysis

In some cases, a lumbar puncture (spinal tap) may be performed to examine cerebrospinal fluid for cancer cells or tumor markers, particularly when certain types of tumors are suspected or to check for leptomeningeal spread (cancer cells in the fluid surrounding the brain and spinal cord).

Blood Tests and Biomarkers

While blood tests can't diagnose brain tumors directly, they may detect hormonal imbalances associated with pituitary tumors or rule out other conditions. Emerging liquid biopsy techniques aim to detect tumor DNA circulating in blood, which may eventually allow for less invasive monitoring of certain brain tumors.

Neuropsychological Evaluation

Comprehensive testing to assess cognitive function, including memory, language, problem-solving, and other intellectual abilities. This provides a baseline for monitoring changes over time and helps guide rehabilitation strategies after treatment.

Treatment Options

Personalized treatment plans tailored to your specific needs and condition

Surgery

Removing as much tumor as safely possible is often the first treatment step for accessible brain tumors. Modern techniques maximize tumor removal while minimizing damage to surrounding healthy tissue. Advanced approaches include awake craniotomy (patient remains awake during surgery to monitor neurological function), intraoperative MRI (real-time imaging during surgery), computer-assisted navigation, fluorescent dye visualization (tumor cells glow when special dye is administered), and laser interstitial thermal therapy (minimally invasive laser treatment). Some deep-seated or critically located tumors may not be suitable for surgical removal.

Radiation Therapy

Uses high-energy beams to destroy tumor cells or slow their growth. External beam radiation delivers radiation from a machine outside the body. Intensity-modulated radiation therapy (IMRT) and proton therapy shape beams precisely to the tumor while minimizing exposure to healthy tissue. Stereotactic radiosurgery (like Gamma Knife or CyberKnife) delivers highly focused radiation in a single or few sessions, particularly useful for small tumors or those in sensitive locations. Brachytherapy implants radioactive sources directly into or near the tumor. Radiation may be used after surgery, as primary treatment when surgery isn't possible, or for recurrent tumors.

Chemotherapy

Uses drugs to kill rapidly dividing cells. May be given orally, intravenously, or directly into the cerebrospinal fluid. The blood-brain barrier prevents many drugs from reaching brain tissue, so special formulations or delivery methods may be needed. Temozolomide is commonly used for gliomas due to its ability to cross the blood-brain barrier. Chemotherapy wafers (Gliadel) placed in the surgical cavity slowly release medication directly to the tumor site. Chemotherapy may be used before or after surgery, often in combination with radiation for certain tumor types.

Targeted Therapy

Drugs that target specific abnormalities in tumor cells. Examples include bevacizumab (Avastin), which targets vascular endothelial growth factor (VEGF) to reduce blood vessel formation in tumors; EGFR inhibitors for tumors with epidermal growth factor receptor alterations; and BRAF inhibitors for tumors with BRAF mutations. Molecular profiling of the tumor helps identify which targeted therapies might be effective. These treatments may have fewer side effects than traditional chemotherapy and are increasingly important in personalized treatment approaches.

Tumor Treating Fields

A non-invasive technique using alternating electric fields delivered through adhesive patches worn on the scalp to disrupt division of cancer cells. FDA-approved for newly diagnosed and recurrent glioblastoma. Patients wear a portable device that creates the electrical fields continuously throughout the day. This approach has shown survival benefits when added to standard treatment for glioblastoma and has minimal side effects compared to other therapies.

Supportive Care

Medications and interventions to manage symptoms and treatment side effects. Anti-seizure medications control tumor-related seizures. Corticosteroids reduce brain swelling and associated symptoms. Pain management strategies address headaches and other discomfort. Physical, occupational, and speech therapy help maintain function and independence. Cognitive rehabilitation addresses thinking and memory problems. Psychosocial support helps patients and families cope with the emotional impact of diagnosis and treatment.

Home Remedies

Seizure Management

Take anti-seizure medications exactly as prescribed without missing doses. Identify and avoid personal seizure triggers, which may include stress, sleep deprivation, or alcohol. Create a safe home environment by padding sharp corners, using shower chairs, and avoiding heights. Educate family members about seizure first aid. Keep a seizure diary to track frequency, duration, and potential triggers to share with your healthcare team.

Fatigue Management

Plan activities for times of day when energy is typically higher. Prioritize essential tasks and ask for help with others. Balance activity with rest periods throughout the day. Light physical activity, as approved by your healthcare team, can paradoxically improve energy levels. Stay hydrated and maintain good nutrition. Discuss persistent fatigue with your healthcare team, as it may be related to treatable conditions like anemia or medication side effects.

Cognitive Support

Use memory aids like notebooks, smartphone apps, alarms, and calendars to compensate for memory difficulties. Establish consistent routines for daily activities. Minimize distractions when focusing on important tasks. Break complex activities into smaller, manageable steps. Schedule mentally demanding tasks during peak cognitive times. Consider formal cognitive rehabilitation therapy with a trained specialist to develop personalized strategies.

Headache Relief

Take pain medications as prescribed, including preventive medications if recommended. Apply cold or warm compresses to the head or neck, whichever provides more relief. Practice relaxation techniques like deep breathing, progressive muscle relaxation, or meditation. Maintain consistent sleep schedules and adequate hydration. Keep a headache diary to identify triggers. Contact your healthcare team promptly for new or changing headache patterns, as they may indicate changes in the tumor or treatment effects.

Emotional Wellbeing

Connect with others through brain tumor support groups, either in-person or online. Practice stress reduction techniques such as mindfulness meditation, guided imagery, or gentle yoga. Maintain open communication with loved ones about your needs and feelings. Consider professional counseling or therapy for persistent anxiety, depression, or difficulty coping. Many cancer centers offer psychosocial support services specifically for brain tumor patients and their families.

Prevention Tips

Most primary brain tumors cannot be prevented as their causes are largely unknown

For those with inherited conditions that increase brain tumor risk, genetic counseling and regular screening may help with early detection

Avoid unnecessary radiation exposure to the head, especially in childhood

If working with known carcinogens, follow safety guidelines and use protective equipment

Maintain a healthy lifestyle with regular physical activity, balanced nutrition, and adequate sleep to support overall health

Recognize and promptly report neurological symptoms like persistent headaches, new seizures, vision changes, or cognitive problems

For patients treated for a brain tumor, attend all scheduled follow-up appointments and imaging studies to monitor for recurrence

To help prevent metastatic brain tumors, follow screening guidelines for cancers that commonly spread to the brain (like lung, breast, and skin cancers)

Wear protective headgear during activities with risk of head injury, though no direct link between traumatic brain injury and brain tumors has been established

Stay informed about emerging research on brain tumor risk factors and prevention strategies

Surgical Solutions

Advanced surgical procedures performed by our expert specialists

Craniotomy

The most common surgical approach for brain tumor removal, involving temporary removal of a section of skull (bone flap) to access the brain. After tumor removal, the bone is replaced and secured. Advances include smaller incisions, specialized instruments, and enhanced visualization techniques. Microsurgical techniques use a surgical microscope for better visualization of small structures. Computer-assisted navigation uses preoperative imaging to create a 3D map of the brain, helping surgeons navigate to the tumor while avoiding critical structures.

Awake Craniotomy

Performed when a tumor is located near areas controlling speech, movement, or other critical functions. The patient is awakened during surgery and asked to perform specific tasks (like speaking or moving limbs) while the surgeon stimulates brain areas near the tumor. This helps identify and preserve functional regions while maximizing tumor removal. The procedure uses specialized anesthesia techniques to ensure patient comfort while allowing necessary participation.

Endoscopic Surgery

Minimally invasive approach using a thin tube with a light and camera (endoscope) inserted through a small incision or natural opening. Particularly useful for tumors in the pituitary gland or ventricular system. Transsphenoidal surgery accesses pituitary tumors through the nasal passage and sphenoid sinus, avoiding brain retraction and craniotomy. Endoscopic techniques typically result in faster recovery, shorter hospital stays, and fewer complications than traditional open approaches for suitable tumors.

Laser Interstitial Thermal Therapy (LITT)

Minimally invasive procedure using laser energy to heat and destroy tumor tissue. A small probe is inserted through a hole in the skull about the size of a pencil eraser. MRI guidance allows precise placement and real-time temperature monitoring to ensure targeted treatment while preserving surrounding healthy tissue. Particularly useful for deep-seated tumors that are difficult to access with traditional surgery, for smaller tumors, or for patients who cannot tolerate open surgery. Also used for radiation necrosis (tissue damage from previous radiation treatment).

Shunt Placement

Addresses hydrocephalus (buildup of cerebrospinal fluid) that can occur with some brain tumors. A thin tube (shunt) is placed in the brain to drain excess fluid to another part of the body, typically the abdomen, where it is absorbed. Programmable shunts allow adjustment of drainage rate without additional surgery. While not a tumor treatment itself, managing hydrocephalus is crucial for symptom relief and may be necessary before, during, or after tumor treatment.
