About the Procedure
What is Stereotactic Body Radiation Therapy (SBRT)?
Stereotactic Body Radiation Therapy (SBRT) is a highly precise, non-invasive radiation technique that delivers very high doses of focused radiation to small, well-defined tumors in the lung, liver, or pancreas over just a few sessions. It uses advanced imaging and immobilization to spare surrounding healthy tissue while achieving tumor control comparable to surgery in select cases. SBRT is commonly used for early-stage or inoperable tumors, oligometastatic disease, or as a boost after other therapies.
Who may be considered?
Stereotactic Body Radiation Therapy (SBRT) 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 a conventional linear accelerator with image-guided radiotherapy (IGRT) and precise immobilization devices to deliver 3-5 high-dose fractions to lung, liver, or pancreatic tumors.
3 approaches available for this procedure:
Linear Accelerator (LINAC)-based SBRT
Most CommonUses a conventional linear accelerator with image-guided radiotherapy (IGRT) and precise immobilization devices to deliver 3-5 high-dose fractions to lung, liver, or pancreatic tumors.
Comprehensive Investigations
Estimated cost: $400 - $1,200
CT simulation scan, PET-CT, pulmonary function tests, liver/kidney function tests, CBC, ECG, tumor marker tests (AFP/CA 19-9), biopsy confirmation report
Treatment / Procedure Estimate
Estimated cost in India: $4,000 - $7,000
Stay in India
Pre-procedure stay (outside hospital): ~3-4 days
Hospitalisation: ~5-6 days (outpatient sessions)
Recovery period (outside hospital): ~7 days recommended
Total stay: approx 14-17 days
Usually Included in Hospital Package
- CT simulation and treatment planning
- Immobilization device fabrication
- 3-5 SBRT treatment sessions
- Radiation oncologist and physicist consultations
- Post-treatment review consultation
Usually Not Included
- Pre-treatment biopsy procedure
- Fiducial marker placement (if required)
- Accommodation and travel costs
- Chemotherapy or systemic therapy
- Long-term follow-up imaging
Recovery and follow-up
Most patients resume normal daily activities within a few days after each session, with mild fatigue or localized irritation being common; follow-up imaging (CT or PET-CT) is typically scheduled 8-12 weeks post-treatment to assess response.
Risks
Potential risks include fatigue, skin irritation, and site-specific effects such as radiation pneumonitis (lung), gastritis or bowel irritation (pancreas), or liver inflammation, with rare risk of damage to adjacent healthy organs.
Alternatives
Alternative options depending on tumor site and stage include conventional fractionated external beam radiotherapy, surgical resection, radiofrequency or microwave ablation, transarterial chemoembolization (TACE) for liver tumors, and systemic chemotherapy.
What we need to prepare a formal estimate
Share whatever you have — the care team will confirm the final checklist after reviewing your case.
Reports required
- Contrast-enhanced CT scan of the chest/abdomen (site-specific)
- PET-CT scan report
- MRI of liver or pancreas (if applicable)
- Biopsy/histopathology report confirming diagnosis
- Tumor marker levels (AFP, CA 19-9, as relevant)
- Pulmonary function test report (for lung cases)
- Liver and kidney function test results
- Prior treatment records (surgery, chemotherapy, or radiotherapy)
Patient information needed
- Patient age and overall performance status
- Exact tumor location, size, and number of lesions
- Cancer stage and prior treatment history
- Current medications and known allergies
- Comorbidities (diabetes, cardiac or respiratory conditions)
- Ability to hold breath or tolerate immobilization for treatment
- Recent lab reports (CBC, liver/kidney function)
- Insurance or payment preference for treatment planning
Costs shown are indicative planning estimates based on typical pricing across leading Indian hospitals. They are not a quote — actual pricing depends on your case complexity, hospital choice, and length of stay. Share your reports for a personalized estimate.

Common questions
FAQs about Stereotactic Body Radiation Therapy (SBRT) in Chennai, India
What is Lung cancer?
Lung cancer is a malignant condition in which cells in one or both lungs multiply abnormally, most commonly arising in the cells lining the airways (non-small cell lung cancer) or in neuroendocrine cells of the lung (small cell lung cancer). The distinction between these types, along with the tumour's stage and molecular profile, directly shapes the treatment approach.
What are the symptoms and health risks of Lung cancer?
Common symptoms include a persistent or worsening cough, coughing up blood, unexplained shortness of breath, chest pain, hoarseness, unintentional weight loss, and recurrent chest infections. As the disease progresses or spreads, symptoms such as bone pain, headache, or swelling in the face and neck may also appear. It is important to note that these symptoms overlap with many other conditions, and their presence alone is not sufficient to establish a diagnosis.
How is Lung cancer diagnosed?
Diagnosis typically begins with a detailed clinical history and physical examination, followed by chest X-ray or CT scan to identify suspicious lesions. A tissue biopsy — obtained bronchoscopically, via CT-guided needle, or surgically — is required to confirm the cancer type and, increasingly, to test for specific genetic mutations (such as EGFR, ALK, or PD-L1 expression) that guide targeted therapy decisions. Staging, usually described using the TNM system (Stage I through IV for non-small cell, and limited versus extensive for small cell), along with PET scan and sometimes brain MRI, determines how far the cancer has spread and which treatment pathways are appropriate.
How is Lung cancer treated?
Treatment depends heavily on the cancer type, stage, molecular markers, and the patient's overall lung function and health status. Early-stage non-small cell lung cancer may be treated with surgery, stereotactic body radiation therapy (SBRT), or a combination of chemotherapy and radiation; advanced stages may involve systemic therapies such as chemotherapy, targeted agents, or immunotherapy, often combined with radiation therapy such as intensity-modulated radiation therapy (IMRT). Small cell lung cancer is generally managed with chemotherapy and radiation, and all decisions about sequencing and combining treatments are made by a multidisciplinary team following individual assessment.
Can Lung cancer be treated without a procedure?
Non-surgical pathways are well established and clinically significant for lung cancer. Stereotactic body radiation therapy (SBRT) is a recognised standard for early-stage tumours in patients who are not surgical candidates or who prefer to avoid surgery. For locally advanced or metastatic disease, chemotherapy, immunotherapy, targeted molecular therapies, and radiation therapy (including IMRT) form the backbone of treatment — meaning many patients receive effective care without any surgical procedure.
When is Stereotactic Body Radiation Therapy (SBRT) considered for Lung cancer?
Stereotactic Body Radiation Therapy (SBRT) 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 Lung cancer?
Lung cancer is typically evaluated and managed by a multidisciplinary team that may include a thoracic oncologist or medical oncologist (who oversees systemic therapies), a radiation oncologist (who plans and delivers SBRT or IMRT), a thoracic surgeon (for surgical cases), and a pulmonologist involved in initial diagnosis. A dedicated lung cancer tumour board — where specialists review each case collectively — is considered best practice at experienced centres.
How do I choose a doctor for Lung cancer?
When comparing providers, look for centres with a dedicated thoracic or lung cancer programme, access to molecular tumour profiling, and an active multidisciplinary tumour board, as these factors are associated with more personalised and coordinated care. It is also worth asking about the radiation oncology team's specific experience with SBRT and IMRT for lung tumours, the technology available (such as image-guided or motion-management systems), and what structured follow-up and supportive care are offered after treatment.
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.
How does GAF Healthcare help international patients plan treatment in India?
Our care coordination team can review the initial information, help identify suitable doctors and hospitals, request a medical opinion where available, explain next steps and indicative cost information, and support practical planning before travel. A remote opinion does not replace an in-person examination or emergency care.
