About the Procedure
What is Stereotactic Radiosurgery (SRS)?
Stereotactic Radiosurgery (SRS) is a highly precise, non-invasive radiation therapy technique used to treat brain tumors, arteriovenous malformations, and other neurological conditions by delivering focused high-dose radiation beams to a small, precisely mapped target while sparing surrounding healthy brain tissue. It is typically performed in a single session or a few sessions using advanced imaging guidance, avoiding the need for open surgery. SRS is commonly recommended for small to medium-sized brain tumors, metastases, and vascular abnormalities, especially when surgery carries higher risk or is not feasible.
Who may be considered?
Stereotactic Radiosurgery (SRS) may be considered after a qualified specialist reviews your reports and medical history. Suitability varies from person to person and must be assessed by your treating doctor.
How does it work?
Uses precisely focused beams of gamma radiation from multiple cobalt-60 sources converging on the target lesion, ideal for small to medium intracranial lesions in a single outpatient session.
2 approaches available for this procedure:
Gamma Knife Radiosurgery
Most PopularUses precisely focused beams of gamma radiation from multiple cobalt-60 sources converging on the target lesion, ideal for small to medium intracranial lesions in a single outpatient session.
Comprehensive Investigations
Estimated cost: $300 - $900
MRI brain with contrast, CT brain, blood tests (CBC, coagulation profile), ECG, neurological examination, stereotactic head frame fitting
Treatment / Procedure Estimate
Estimated cost in India: $5,000 - $9,500
Stay in India
Pre-procedure stay (outside hospital): ~1 day
Hospitalisation: ~1 day
Recovery period (outside hospital): ~3-5 days recommended
Total stay: approx 5-7 days
Usually Included in Hospital Package
- Consultation with neuro-oncologist/radiation oncologist
- Stereotactic head frame placement
- Treatment planning imaging and dosimetry
- Single-session Gamma Knife treatment
- Post-procedure observation and initial follow-up
Usually Not Included
- International flights and visa costs
- Hotel accommodation for accompanying family
- Long-term MRI follow-up scans
- Treatment of unrelated medical conditions
- Medications for chronic pre-existing illness
Recovery and follow-up
Most patients resume normal daily activities within a few days to a week, with follow-up MRI scans typically scheduled at 3, 6, and 12 months to monitor treatment response. Mild fatigue or headache may occur temporarily after the procedure.
Risks
While SRS is minimally invasive, potential risks include temporary swelling, headache, fatigue, and in rare cases, radiation-induced changes to nearby healthy brain tissue or delayed neurological effects.
Alternatives
Alternative treatments may include conventional fractionated radiotherapy, open microsurgical resection, or a combination of surgery with adjuvant radiation, depending on tumor size, location, and patient condition.

Common questions
FAQs about Stereotactic Radiosurgery (SRS) in Chennai, India
What is Brain Tumors?
A brain tumor is an abnormal mass of cells growing in or around the brain, classified as benign (non-cancerous) or malignant (cancerous), and further distinguished by whether it started in the brain (primary) or spread from another part of the body (secondary or metastatic).
What are the symptoms and health risks of Brain Tumors?
Common symptoms include persistent or worsening headaches (often worse in the morning), seizures, nausea and vomiting, vision or hearing changes, weakness or numbness on one side of the body, balance difficulties, and gradual changes in memory, personality, or speech. The type, severity, and pattern of symptoms are strongly influenced by the tumor's location within the brain and its rate of growth. It is important to note that these symptoms overlap with many other neurological conditions, and symptoms alone are never sufficient to establish a diagnosis.
How is Brain Tumors diagnosed?
Diagnosis typically begins with a detailed neurological history and physical examination, followed by magnetic resonance imaging (MRI) with contrast—the primary imaging standard for evaluating brain tumors—and sometimes computed tomography (CT) when MRI is not available or to assess bone involvement. Tumors are graded (most commonly using the WHO grading system, Grades 1–4) to reflect how aggressive the cells appear under microscopy, which guides both prognosis and treatment planning. In many cases a tissue biopsy or surgical sample is required to confirm the tumor type and molecular markers, as these directly influence which treatment approach is most appropriate for that individual.
How is Brain Tumors treated?
Treatment for brain tumors is highly individualized and depends on the tumor's grade, type, size, location, molecular profile, and the patient's overall health and neurological status. Options range from active surveillance for small, slow-growing benign tumors to surgical resection, radiation therapy (including highly targeted techniques such as Stereotactic Radiosurgery and Gamma Knife Radiosurgery), chemotherapy, and combinations of these approaches. The appropriate path is determined through a multidisciplinary evaluation, and no single plan can be recommended without a qualified clinician reviewing that individual's full clinical picture.
Can Brain Tumors be treated without a procedure?
Non-procedural management plays a meaningful role for certain brain tumors: small, asymptomatic, slow-growing tumors (such as low-grade meningiomas or acoustic neuromas in older patients) may be managed with active surveillance using periodic MRI and clinical review. When the tumor requires treatment but surgery carries unacceptable risk due to location or patient health, radiation-based approaches—particularly Stereotactic Radiosurgery (SRS) or Gamma Knife Radiosurgery—can deliver precisely targeted radiation to the tumor without an open surgical incision, and chemotherapy or targeted drug therapy may be used alongside or instead of radiation depending on tumor biology. A complete non-interventional pathway is less common for high-grade or rapidly progressing tumors, where some form of active treatment is usually necessary.
When is Stereotactic Radiosurgery (SRS) considered for Brain Tumors?
Stereotactic Radiosurgery (SRS) 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.
Which doctor treats Brain Tumors?
Brain tumors are managed by a multidisciplinary team that typically includes a neuro-oncologist (a neurologist specializing in brain cancer), a neurosurgeon for cases requiring surgical intervention or biopsy, and a radiation oncologist who specializes in planning and delivering treatments such as Stereotactic Radiosurgery and Gamma Knife Radiosurgery. Depending on tumor type and treatment needs, a medical oncologist may also be involved in coordinating systemic therapies such as chemotherapy or targeted agents.
How do I choose a doctor for Brain Tumors?
When evaluating providers, look for a radiation oncologist or neurosurgeon with documented experience in brain tumor management and access to advanced radiosurgery technology (such as a dedicated Gamma Knife or linear accelerator-based SRS system), ideally within a center that operates a formal multidisciplinary tumor board. Confirm that the facility offers comprehensive follow-up imaging, neurological monitoring, and clear coordination between oncology, neurosurgery, and supportive care teams, as ongoing management after initial treatment is critical to outcomes.
What documents do international patients need to share for a medical evaluation?
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.
