Metastatic brain tumor surgery treats cancer that has spread to the brain from another part of the body, such as the lung, breast, kidney, skin, or colon. Treatment may include craniotomy, stereotactic radiosurgery, radiation therapy, chemotherapy, targeted therapy, or a combination of treatments to relieve symptoms, preserve neurological function, and improve quality of life.
What Is a Metastatic Brain Tumor?
A metastatic brain tumor, also called a secondary brain tumor or brain metastasis, develops when cancer cells spread from another part of the body to the brain. Metastatic tumors are more common than primary brain tumors in adults.
These tumors may affect:
- Brain tissue
- Cranial nerves
- Cerebellum
- Brainstem
- Meninges
- Surrounding blood vessels
Common cancers that spread to the brain include:
- Lung cancer
- Breast cancer
- Melanoma
- Kidney cancer
- Colon cancer
At Midwest Spine & Brain Institute, our neurosurgical team evaluates complex brain tumors using advanced imaging, neurological testing, and multidisciplinary treatment planning across Minnesota and western Wisconsin.
Patients with metastatic tumors may also require evaluation through our Brain Tumor Surgery and Brain Tumors – Adult & Pediatric programs.
Symptoms of Metastatic Brain Tumors
Symptoms depend on the tumor’s size, number, and location within the brain.
Common Symptoms Include:
- Persistent headaches
- Seizures
- Weakness or numbness
- Difficulty walking or balance problems
- Vision changes
- Speech difficulties
- Memory loss or confusion
- Personality or behavior changes
- Nausea and vomiting
- Coordination problems
Symptoms may develop gradually or suddenly if swelling or bleeding occurs around the tumor.
Patients experiencing new neurological symptoms should seek immediate medical evaluation.
Causes and Risk Factors
Metastatic brain tumors occur when cancer cells travel through the bloodstream or lymphatic system to the brain.
Risk Factors Include:
- Existing cancer diagnosis
- Advanced-stage cancer
- Aggressive tumor biology
- Melanoma or lung cancer history
- Multiple metastatic lesions
- Immune suppression
Some metastatic tumors grow rapidly and may increase pressure inside the skull, requiring urgent treatment.
How Metastatic Brain Tumors Are Diagnosed
Accurate diagnosis is critical for determining the safest and most effective treatment plan.
Diagnostic Testing May Include:
MRI of the Brain
MRI with contrast is the gold-standard imaging study for identifying brain metastases, swelling, bleeding, and surrounding brain involvement.
CT Scan
CT imaging may be used in emergency situations or when bleeding is suspected.
Neurological Examination
A neurological exam evaluates:
- Reflexes
- Vision
- Strength
- Coordination
- Speech
- Cognitive function
Biopsy
A biopsy may be performed during surgery or through stereotactic techniques to confirm tumor type and guide treatment decisions.
Advanced Tumor Analysis
Pathology and molecular testing may identify:
- Tumor origin
- Genetic mutations
- Biomarkers
- Treatment-sensitive targets
Patients with complex vascular or deep brain tumors may also benefit from evaluation through our Complex Brain Surgery and Craniotomy programs.
Treatment Options for Metastatic Brain Tumors
Treatment depends on:
- Number of tumors
- Tumor location
- Cancer type
- Neurological symptoms
- Overall health
- Prior cancer treatment history
Many patients receive a combination of therapies.
Stereotactic Radiosurgery (SRS)
Stereotactic radiosurgery precisely delivers focused radiation to metastatic tumors while minimizing exposure to healthy brain tissue.
Benefits of Radiosurgery:
- Non-invasive treatment
- Outpatient option for many patients
- Minimal recovery time
- High precision targeting
- Effective for small or multiple tumors
Related treatments include:
Metastatic Brain Tumor Surgery
Surgery may be recommended when:
- The tumor causes pressure on the brain
- Significant neurological symptoms are present
- Tissue diagnosis is needed
- The tumor is accessible for safe removal
- A large lesion requires decompression
Craniotomy for Tumor Removal
A craniotomy is the most common surgical approach for metastatic brain tumor removal.
During surgery:
- A section of skull bone is temporarily removed.
- Advanced imaging and microsurgical techniques guide tumor removal.
- The surgeon removes as much tumor tissue as safely possible.
- The skull is reconstructed and secured.
The primary goal is maximal safe tumor removal while protecting healthy brain tissue and neurological function.
Patients with advanced tumors near critical structures may require specialized Skull Base Surgery or Craniotomy for Tumor Resection procedures.
Additional Treatments
Depending on the cancer type, treatment may also include:
- Chemotherapy
- Immunotherapy
- Targeted therapy
- Whole-brain radiation therapy
- Steroids to reduce swelling
- Anti-seizure medications
- Rehabilitation therapy
Care plans are coordinated with oncology, radiation oncology, neuroradiology, and neurosurgery specialists.
Benefits of Metastatic Brain Tumor Surgery
Potential benefits include:
- Reduced brain pressure
- Improved neurological function
- Relief of headaches and seizures
- Better mobility and coordination
- Tissue diagnosis for treatment planning
- Improved quality of life
Outcomes vary depending on tumor biology, overall health, and treatment response.
Risks and Complications
All brain procedures carry potential risks.
Possible complications include:
- Bleeding
- Infection
- Stroke
- Seizures
- Neurological deficits
- Brain swelling
- Fluid buildup
- Tumor recurrence
MSBI surgeons use advanced microsurgical techniques, neuronavigation, and imaging technologies to support patient safety and precision.
Recovery After Metastatic Brain Tumor Surgery
Recovery varies based on:
- Tumor size
- Number of lesions
- Surgical complexity
- Overall health
- Additional cancer treatments
Recovery May Include:
- Hospital monitoring
- Pain management
- Physical therapy
- Occupational therapy
- Speech therapy
- Follow-up MRI scans
- Oncology follow-up care
Some patients resume light activities within weeks, while others require longer rehabilitation.
When to See a Brain Tumor Specialist
Seek urgent evaluation if you experience:
- New seizures
- Sudden weakness
- Persistent headaches
- Vision loss
- Balance problems
- Confusion or personality changes
- Known cancer with new neurological symptoms
Early diagnosis and treatment can help reduce complications and improve neurological outcomes.

Frequently Asked Questions
What is a metastatic brain tumor?
A metastatic brain tumor is cancer that spreads to the brain from another part of the body, such as the lungs, breast, skin, or kidneys.
Can metastatic brain tumors be removed surgically?
Yes. Surgery may be recommended if the tumor is accessible, causing symptoms, or creating pressure inside the brain.
What is the survival rate after metastatic brain tumor surgery?
Survival varies widely based on cancer type, number of metastases, overall health, and treatment response. Your neurosurgeon and oncology team will discuss individualized expectations.
Is stereotactic radiosurgery the same as traditional surgery?
No. Stereotactic radiosurgery uses focused radiation beams and does not require an incision.
What symptoms do metastatic brain tumors cause?
Common symptoms include headaches, seizures, weakness, speech problems, balance issues, memory changes, and vision disturbances.
Can metastatic brain tumors come back?
Yes. Ongoing MRI monitoring and follow-up care are important because recurrence or new metastatic lesions can occur.
How long is recovery after craniotomy?
Recovery varies by patient and procedure complexity. Some patients recover within weeks, while others need rehabilitation and ongoing cancer treatment.
Are metastatic brain tumors always cancerous?
Yes. By definition, metastatic brain tumors originate from cancer elsewhere in the body.
Can radiosurgery treat multiple tumors?
Yes. Stereotactic radiosurgery is commonly used to treat one or multiple metastatic brain lesions.
When should someone seek emergency care?
Emergency evaluation is needed for sudden weakness, seizures, severe headaches, confusion, or rapidly worsening neurological symptoms.
