Why consider treatment in India?
Many international patients consider India for liver cancer treatment for several reasons, including:
More affordable estimates
Competitive indicative costs compared with many other countries, for similar clinical standards.
Internationally accredited hospitals
Hospitals experienced in treating international patients.
Experienced specialists
Doctors who regularly manage similar cases.
Care coordination support
A team to help with planning, medical translation and follow-up.
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 Liver Cancer?
Liver cancer is a malignant growth arising in the liver tissue, most often hepatocellular carcinoma developing on a background of chronic liver disease or cirrhosis. Less commonly, it may originate in the bile ducts within the liver (intrahepatic cholangiocarcinoma) or spread to the liver from another primary site.
What are the symptoms and health risks of Liver Cancer?
Early-stage liver cancer frequently causes no noticeable symptoms, which is why it is often found during surveillance of high-risk patients. When symptoms do appear they may include persistent upper-right abdominal pain or a sense of fullness, unexplained weight loss, loss of appetite, jaundice (yellowing of the skin or eyes), fatigue, or abdominal swelling from fluid accumulation. These symptoms overlap with many other liver and gastrointestinal conditions, so their presence alone is not sufficient to establish a diagnosis.
How is Liver Cancer diagnosed?
Diagnosis typically begins with a detailed clinical history and physical examination, followed by blood tests including liver function panels and tumour markers such as AFP. Cross-sectional imaging—most commonly multiphase contrast-enhanced CT or MRI—is central to characterising the lesion and is often sufficient for diagnosis in the context of cirrhosis using established criteria (such as LI-RADS or EASL guidelines). Staging—most commonly using the Barcelona Clinic Liver Cancer (BCLC) system—integrates tumour size, number, vascular invasion, liver function (Child-Pugh score), and performance status to guide treatment planning; a tissue biopsy is obtained when imaging findings are inconclusive.
How is Liver Cancer treated?
Treatment is highly individualised and depends on tumour stage, underlying liver function, and the patient's overall health. Surgical options such as hepatic resection (surgical removal of the tumour-bearing portion of the liver) or liver transplantation offer the best chance of long-term disease control for eligible patients, while locoregional therapies—including radiofrequency ablation (RFA), transarterial chemoembolisation (TACE), and stereotactic body radiotherapy (SBRT)—are used for patients who are not suitable candidates for surgery. Systemic therapies, including targeted agents such as sorafenib or lenvatinib and immunotherapy combinations, are options for advanced-stage disease.
Can Liver Cancer be treated without a procedure?
Non-surgical pathways play a significant role in liver cancer management and are not limited to palliative intent. Locoregional treatments such as TACE, thermal ablation, or radioembolisation (SIRT) can achieve meaningful tumour control in intermediate-stage disease, and systemic targeted therapy or immunotherapy is the standard approach for advanced HCC. Active surveillance with regular imaging and AFP testing is an established strategy for very small, low-risk lesions identified in cirrhotic patients, with treatment initiated if the tumour progresses—all decisions are made on an individual basis by the treating team.
When is Stereotactic Body Radiation Therapy (SBRT) considered for Liver 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 Liver Cancer?
Liver cancer is typically managed by a hepatobiliary or surgical oncologist who specialises in liver surgery, working within a multidisciplinary team that usually includes a hepatologist (liver physician), a medical oncologist, an interventional radiologist, and a radiation oncologist. In cases where transplantation is considered, a transplant hepatologist and transplant surgeon are also involved.
How do I choose a doctor for Liver Cancer?
When selecting a provider, look for a surgeon or centre with documented experience in hepatic resection and liver cancer specifically, with access to a formal multidisciplinary tumour board, advanced imaging and locoregional treatment capabilities, and a clear plan for post-treatment surveillance and follow-up care.
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.
