Estimated cost: $3,000 – $7,000 · Average stay: 1–2 days
Radiofrequency ablation (RFA) uses high-frequency electrical current to generate heat within tumour tissue, destroying cancer cells. A needle electrode is inserted directly into the tumour under imaging guidance; radiofrequency energy is passed through the electrode, heating the surrounding tissue to 60–100°C and producing coagulative necrosis.
RFA is the most widely performed thermal ablation technique for primary liver cancer (hepatocellular carcinoma) and liver metastases from colorectal cancer. It is also used for renal cell carcinoma, lung metastases, adrenal metastases, bone metastases causing pain, and thyroid nodules.
India's interventional radiology and hepatology departments at Apollo, Medanta, Fortis, and Kokilaben Dhirubhai Ambani Hospital perform hundreds of RFA procedures each year. Procedure costs of $3,000–$7,000 compare to $15,000–$30,000 in Western countries.
How Does Radiofrequency Ablation Work?
An RFA electrode (a special needle with deployable tines at the tip) is inserted into the tumour under CT, ultrasound, or MRI guidance. Radiofrequency electrical current passes between the electrode and grounding pads on the patient's skin. The electrical resistance of tissue generates heat around the electrode tip. Temperatures of 60°C cause immediate coagulative necrosis; temperatures of 100°C cause boiling and carbonization which can impede further energy transmission.
Modern "cool-tip" electrodes circulate internal saline cooling to prevent charring at the electrode tip, allowing higher total energy delivery and larger ablation zones. Ablation zones of 3–5 cm diameter can be achieved, sufficient for most tumours up to 3 cm in diameter.
Who is a Candidate for RFA?
RFA is suitable for patients with: liver HCC with up to 3 lesions of ≤5 cm each (or a single lesion ≤7 cm); colorectal liver metastases not amenable to surgical resection; renal tumours ≤4 cm (T1a); lung metastases ≤3 cm in number ≤3; symptomatic bone metastases (osteolytic); and thyroid nodules requiring ablation as an alternative to thyroidectomy.
Patients with coagulopathy (INR >1.5) should have this corrected before RFA. Tumours adjacent to major hepatic veins or the main portal vein may be poorly ablated due to the "heat sink" effect (blood flow carrying heat away from the treatment zone). Biliary tumours are at risk of stricture after RFA near bile ducts.
How is the RFA Procedure Performed?
The patient lies in the CT or ultrasound suite. Under conscious sedation or general anaesthesia, the skin is cleaned and the electrode inserted through a 2–3mm skin nick directly into the tumour under continuous imaging guidance. Radiofrequency energy is applied for 10–20 minutes per ablation site. Multiple overlapping ablations may be required for larger tumours or to achieve an adequate safety margin. The electrode is removed, the entry point is sealed (sometimes coagulated with RFA on withdrawal to prevent bleeding), and the patient observed for 2–4 hours.
Procedure Steps
- Pre-procedure CT/MRI confirms tumour size, number, and proximity to vessels and bile ducts.
- Patient positioned; sedation or general anaesthesia administered.
- Skin prep and draping; entry point marked under imaging guidance.
- Electrode insertion to the centre of the tumour through a 2–3mm skin nick.
- Radiofrequency energy applied; real-time temperature and impedance monitoring.
- Ablation repeated at adjacent sites if tumour size requires multiple overlapping zones.
- Electrode withdrawal with ablation of tract to prevent bleeding.
- Post-procedure imaging to confirm ablation zone covers the tumour with margin.
- Observation for 2–4 hours; discharge same day or next morning.

RFA in India costs $3,000–$7,000 all-inclusive. Liver RFA at Apollo or Medanta costs approximately $3,500–$5,500 per session. The same procedure costs $15,000–$30,000 in the United States. Multiple sessions may be required for multiple tumours.
Recovery & Follow-up
RFA is typically a same-day or next-day discharge procedure. Patients experience mild pain, fever (post-ablation syndrome), and fatigue for 3–5 days. Return to normal activity occurs within 1–2 weeks. Follow-up CT or MRI at 1 month confirms complete ablation or identifies areas requiring re-treatment.
Recovery Tips
- Rest for 48 hours after the procedure; avoid strenuous activity for 1 week.
- Mild fever (37–38.5°C) is expected for 2–3 days post-ablation (post-ablation syndrome); paracetamol is adequate.
- Report any severe pain, high fever (>39°C), or jaundice immediately.
- Maintain adequate oral hydration.
- Attend 1-month follow-up CT/MRI; early detection of incomplete ablation allows prompt re-treatment.
Risks & Complications
RFA risks include post-ablation syndrome (fever, malaise — in 50% of patients, resolves within a week), pain, bleeding (1–2%), biliary injury with bile leak or stricture (for liver RFA near bile ducts), pneumothorax (for lung RFA, 10–15%), skin burns at grounding pad sites, and incomplete ablation requiring repeat treatment. Major complication rates at experienced centres are below 3%.
Why GAF Healthcare
Gaf Healthcare's interventional oncology coordinators arrange RFA consultations with experienced hepatobiliary interventional radiologists and hepatologists. We review your imaging to confirm suitability before arranging travel. Post-RFA follow-up imaging can be performed locally; we coordinate remote review by the treating team.
Frequently Asked Questions
How many RFA sessions will I need?
Most patients require 1–2 sessions. Multiple tumours may be treated in the same session if they are accessible from the same approach. Repeat RFA is performed at 1 month if imaging shows incomplete ablation.
Is RFA as effective as surgery for liver cancer?
For HCC tumours ≤3 cm, RFA achieves local tumour control equivalent to surgical resection in most randomised trials, with lower morbidity. For larger tumours or when surgery is feasible, resection generally offers better long-term results.
Can RFA be done for patients with cirrhosis?
Yes. RFA is specifically valuable for cirrhotic patients who are high surgical risk. It can be performed safely in patients with Child-Pugh A and selected B cirrhosis.
Will I need to stay in India after RFA?
Most patients stay 2–4 days after liver or kidney RFA. We arrange a 30-minute post-procedure check and basic liver function/blood tests before discharge. The 1-month follow-up CT can be performed locally with remote review by the treating team.
Is RFA painful?
The procedure is performed under sedation or general anaesthesia so patients feel nothing during the treatment. Post-procedure pain is typically mild to moderate and managed with oral analgesics.
