Best Neurosurgeons for Craniotomy in Chennai, India

A brain tumor is an abnormal mass of cells that develops in or around the brain; it may be benign (non-cancerous but potentially harmful depending on size and location) or malignant (cancerous, with a tendency to grow aggressively and affect surrounding structures).

Common symptoms can include persistent or worsening headaches (often worse in the morning), seizures, changes in vision, speech or memory, unexplained nausea or vomiting, weakness or numbness in the limbs, and shifts in personality or cognition. The type, location, and size of the tumor strongly influence which symptoms appear, and some tumors may grow with few noticeable symptoms until they reach a significant size. Experiencing any of these symptoms does not confirm the presence of a brain tumor, and only a qualified clinician can determine the cause through proper evaluation.

Diagnosis typically begins with a detailed neurological examination and a review of the patient's personal and family medical history, followed by advanced imaging—most commonly MRI with contrast, which can reveal the tumor's size, location, and relationship to surrounding structures. A CT scan may also be used, particularly in urgent settings. Definitive diagnosis and tumor classification—including grading on the WHO scale from Grade I (slow-growing, typically benign) to Grade IV (highly aggressive, such as glioblastoma)—generally requires a tissue biopsy, which informs prognosis and guides treatment decisions.

Treatment depends on the tumor's type, WHO grade, size, location, the patient's overall health, and neurological status, and is best determined through a multidisciplinary team assessment. Surgical removal (resection) via craniotomy is a common primary approach for many tumors, aiming to reduce tumor burden, relieve pressure, and obtain tissue for diagnosis. Depending on the findings, surgery may be combined with or replaced by radiation therapy, chemotherapy, targeted therapy, or active surveillance, particularly for low-grade or inoperable tumors.

For certain low-grade or slow-growing benign tumors—especially in older patients or those with significant surgical risk—active surveillance with periodic MRI scans may be an appropriate initial strategy. Radiation therapy (including stereotactic radiosurgery such as Gamma Knife or CyberKnife) and chemotherapy are established non-surgical or adjunct options, particularly for malignant tumors, recurrent disease, or tumors in locations that make surgical access difficult. Corticosteroids may be prescribed to manage swelling around the tumor, and anti-epileptic medications are commonly used when seizures are present. All non-surgical plans must be assessed and monitored by a specialist.

Craniotomy may be considered only when it is appropriate for the confirmed diagnosis and the expected benefit outweighs the individual risks. The decision may depend on symptom severity, investigation results, previous treatment, overall health and the patient's goals. A specialist should discuss alternatives and recovery before any procedure is planned.

Brain tumors are primarily evaluated and managed by a neurosurgeon, and most treatment decisions are made within a multidisciplinary team that also includes a neuro-oncologist, a radiation oncologist, and a specialist neuroradiologist. A neurologist may also be involved in ongoing symptom management, particularly for seizure control.

When comparing providers, look for a neurosurgeon with documented experience in brain tumor resection and craniotomy, ideally affiliated with a hospital that has a dedicated neuro-oncology program, intraoperative neurophysiological monitoring, and access to adjunct therapies such as radiation and chemotherapy. Confirm that the team offers structured post-operative follow-up, including repeat imaging and rehabilitation support where needed.

Share a concise medical summary, symptom timeline, previous diagnoses, investigation and imaging reports, procedure or biopsy reports where relevant, current medicines, allergies and related treatment records. Provide clear copies with translations when needed. The reviewing doctor may request additional information before giving an opinion.
