What Are Brain Tumors?
A brain tumor is an abnormal growth of cells within the brain or the central spinal canal. Brain tumors may be primary — originating in the brain itself — or secondary (metastatic), having spread from cancers elsewhere in the body such as the lung, breast, or colon. Primary brain tumors range from slow-growing benign lesions to highly aggressive malignancies. Neurosurgery also encompasses the treatment of cerebrovascular conditions, spinal disorders, and functional neurological diseases. Shanghai's Huashan Hospital, affiliated with Fudan University, is one of Asia's most renowned neurosurgical centers, consistently ranked among China's top hospitals for neurology and neurosurgery.
Common Neurosurgical Conditions
- Glioma — the most common primary brain tumor; includes low-grade glioma, glioblastoma multiforme (GBM), and astrocytoma
- Meningioma — typically benign tumor arising from the meninges; often large and requiring surgical removal
- Pituitary adenoma — benign tumor of the pituitary gland causing hormonal dysfunction and visual disturbance
- Acoustic neuroma (vestibular schwannoma) — benign tumor of the hearing nerve causing hearing loss and balance problems
- Brain metastases — secondary tumors from lung, breast, melanoma, and other primary cancers
- Cerebral arteriovenous malformation (AVM) — abnormal tangle of blood vessels prone to hemorrhage
- Cerebral cavernous malformation — clusters of abnormal blood vessels that can bleed
- Trigeminal neuralgia — severe facial pain caused by nerve compression
- Hydrocephalus — abnormal accumulation of cerebrospinal fluid in the brain
- Spinal tumors — intradural, extradural, and intramedullary spinal cord tumors
- Deep brain stimulation (DBS) for Parkinson's disease — surgical implantation of electrodes to control motor symptoms
Symptoms
Symptoms depend on tumor location and size:
- Persistent or worsening headaches, especially in the morning
- Seizures — new onset in an adult always warrants brain imaging
- Cognitive changes — memory loss, confusion, personality changes
- Weakness or numbness in the arms or legs
- Speech or language difficulties (aphasia)
- Vision changes — blurred vision, double vision, or visual field loss
- Balance and coordination problems
- Nausea and vomiting (from raised intracranial pressure)
- Hearing loss or tinnitus (acoustic neuroma)
- Hormonal symptoms — amenorrhea, galactorrhea, acromegaly (pituitary tumors)
Causes & Risk Factors
- Ionizing radiation exposure — prior cranial radiation therapy increases risk
- Genetic syndromes — neurofibromatosis (NF1, NF2), Li-Fraumeni syndrome, Von Hippel-Lindau disease, tuberous sclerosis
- Immune suppression — increases risk of primary CNS lymphoma
- Age — glioblastoma most common in adults over 60; medulloblastoma more common in children
- Family history of brain tumors
- For metastatic tumors: underlying primary cancer (lung, breast, melanoma, renal, colorectal)
Diagnosis
Huashan Hospital's neurosurgery team uses state-of-the-art neuroimaging and intraoperative technology:
- MRI brain with contrast (gadolinium) — the gold standard for brain tumor detection and characterization
- MR spectroscopy — to differentiate tumor from radiation necrosis and assess metabolic activity
- Functional MRI (fMRI) — to map eloquent cortex (language, motor areas) before surgery
- Diffusion tensor imaging (DTI) — to visualize white matter tracts and plan safe surgical corridors
- CT scan — for acute hemorrhage, calcification, and bone involvement
- PET scan — for metabolic tumor activity and metastasis detection
- Stereotactic biopsy — minimally invasive tissue sampling for histological and molecular diagnosis
- Molecular profiling — IDH mutation, MGMT methylation, 1p/19q codeletion, EGFR amplification — critical for glioma classification and treatment planning
- Visual field testing and neuro-ophthalmology assessment — for pituitary and optic pathway tumors
Treatment Options
Huashan Hospital offers the full spectrum of neurosurgical and neuro-oncological treatments:
- Microsurgical tumor resection — the cornerstone of brain tumor treatment; Huashan Hospital performs one of the highest volumes of craniotomies in China with excellent outcomes
- Awake craniotomy — surgery performed while the patient is conscious to preserve language and motor function in eloquent brain areas
- Neuronavigation-guided surgery — GPS-like real-time surgical guidance for precise tumor localization
- Intraoperative MRI (iMRI) — real-time imaging during surgery to maximize tumor resection while preserving function
- Intraoperative fluorescence (5-ALA) — tumor-specific fluorescent dye to distinguish tumor from normal brain tissue
- Endoscopic neurosurgery — minimally invasive transsphenoidal approach for pituitary adenomas; endoscopic third ventriculostomy for hydrocephalus
- Stereotactic radiosurgery (Gamma Knife / CyberKnife) — highly precise radiation for small tumors, AVMs, acoustic neuromas, and brain metastases; avoids open surgery
- Radiation therapy — conventional fractionated radiotherapy or IMRT post-surgery for malignant gliomas and metastases
- Temozolomide chemotherapy — standard adjuvant treatment for glioblastoma (Stupp protocol)
- Tumor treating fields (TTFields) — Optune device for glioblastoma; available at select Shanghai centers
- Microvascular decompression (MVD) — surgical treatment for trigeminal neuralgia and hemifacial spasm
- Deep brain stimulation (DBS) — for Parkinson's disease, essential tremor, and dystonia
- Ventriculoperitoneal (VP) shunt — for hydrocephalus management
