When surgery is risky, the tumour is hard to reach, or you simply want to avoid the operating table, CyberKnife offers a powerful alternative. A robotic arm delivers hundreds of pinpoint radiation beams to the tumour with sub-millimetre accuracy — tracking it in real time, even as you breathe — while sparing the healthy tissue around it. No incision, no blood loss, no general anaesthesia, no hospital stay. Treatment is completed in just 1–5 painless sessions. Medifly's senior radiation oncologists in Chennai deliver this on the same Accuray platform used worldwide, at $5,500–$8,500 all-inclusive — 60–90% less than the US or UK.
CyberKnife is a form of robotic radiosurgery. Despite the name, nothing is cut. Instead, a compact linear accelerator mounted on a flexible robotic arm fires hundreds of finely focused radiation beams at a tumour from many different angles. Where the beams cross, they deliver a powerful, tumour-destroying dose — while each individual beam passes through healthy tissue too weakly to harm it. The result is the precision of a scalpel delivered entirely by radiation.
What makes CyberKnife unique is its real-time tracking. Continuous X-ray imaging follows the tumour throughout the session and the robotic arm constantly re-aims to compensate for the smallest movement — even the rise and fall of your chest as you breathe. According to the National Cancer Institute ↗, stereotactic techniques like this allow very high, precise doses to be delivered safely in far fewer sessions than conventional radiation.
At Medifly Healthcare's partner hospitals, radiation oncologists and medical physicists work as one team to plan and deliver every treatment. Whether the target is a brain or spine tumour, a lung, liver or pancreatic lesion, prostate cancer, or a benign condition like trigeminal neuralgia, the same world-class technology and the same internationally trained specialists are available at a fraction of Western prices. For many patients it is the ideal answer when conventional radiation therapy would take too long, or when open surgery carries too much risk.
Whether you have been told your tumour is inoperable, you are dreading weeks of daily radiation, or you have been quoted an impossible price abroad, these are the questions that keep patients awake at night — and exactly how we resolve them.
Many tumours sit in places open surgery cannot safely reach — deep in the brain, wrapped around the spine, or beside vital organs. CyberKnife changes that picture entirely. Because the dose is delivered by beams from outside the body, the robot can reach targets a surgeon's hands cannot, with no cutting at all. "Inoperable" rarely means "untreatable" once CyberKnife is on the table.
Our radiation oncologists review your scans and tell you honestly whether CyberKnife can treat your specific tumour — within 24 hours of receiving your reports.
Conventional radiotherapy often means 30–40 sessions over six to eight weeks — exhausting, especially for someone travelling from another country. CyberKnife delivers the entire course in just 1–5 sessions over one or two weeks, thanks to the very high precision dose. Far less time off work, far less time away from home, far less fatigue.
We compress your whole journey — arrival, planning, treatment and review — into a single short trip, and coordinate everything end to end.
In the US a single CyberKnife session can cost $35,000–$45,000; in the UK around £22,000. For most families that is out of reach. In India the same Accuray technology costs $5,500–$8,500 for the full course — typically 60–90% less — delivered by radiation oncologists with equivalent international training, at JCI-accredited hospitals.
You receive a clear, written, all-inclusive package up front — no hidden charges, no surprises, with hospital and pricing matched to your case.
Recurrence after previous radiotherapy is one of the most frightening situations a patient can face, because tissue can usually only be irradiated to a limited total dose. CyberKnife's pinpoint accuracy makes re-treatment possible in many cases where broad-beam radiation cannot be repeated — concentrating dose on the recurrence while sparing already-treated tissue.
We arrange a specialist re-irradiation review so you get a clear, expert opinion on whether CyberKnife can safely treat a recurrent tumour.
Arranging treatment in another country can feel overwhelming: visas, flights, choosing a hospital, understanding the plan, language, accommodation, and someone to lean on through it all. Medifly handles the entire pathway for you. From the moment you send your reports, a single coordinator who knows your case manages every step — so you can focus on getting well, not on logistics. Because CyberKnife needs no hospital admission and recovery is so quick, most international patients spend only one to two weeks in India and fly home soon after the final session.
Medical visa support, airport pickup, hospital matching, accommodation near the centre, multi-language coordinators, and lifelong follow-up coordination with your home doctor — all arranged for you. See how medical tourism with Medifly works →
CyberKnife itself is fast and painless. Getting to the right plan, the right hospital and back home safely is where Medifly does the heavy lifting — so the only thing you have to think about is your recovery.
Your scans are reviewed by senior radiation oncologists and a medical physics team who confirm whether CyberKnife is right for your tumour and design the treatment plan.
We match you to the right NABH/JCI-accredited CyberKnife centre and give you a clear, all-inclusive written package before you commit to anything.
For international patients we organise the full logistics so the trip is short, smooth and relaxed from landing to take-off.
Understanding exactly what happens removes most of the fear. CyberKnife is delivered in clear, well-defined stages — and the treatment itself is one of the calmest experiences in modern cancer care.
A high-resolution CT, often with MRI or PET, maps the exact size, shape and location of the tumour. For soft-tissue targets (prostate, liver, pancreas) tiny gold markers called fiducials may be placed first as tracking reference points.
The radiation oncologist and medical physicist use the scans to outline the tumour and the structures to protect, then design a plan that shapes the dose precisely to the target. This planning step takes a few days — no patient needed.
You lie comfortably on the couch — no rigid frame, no anaesthesia. The robotic arm moves around you, delivering beams from many angles while live imaging tracks the tumour. Each session lasts about 30–60 minutes.
There is no wound and no hospital stay — most people resume normal activity within a day or two. The tumour shrinks gradually over weeks to months. Follow-up imaging confirms the response and is coordinated with your home doctor.
CyberKnife treats cancerous and non-cancerous (benign) tumours almost anywhere, plus selected non-tumour conditions. Below are the most common applications offered at Medifly's partner centres.
Primary brain tumours, acoustic neuromas, meningiomas, pituitary adenomas, and brain metastases. The skull is tracked directly, so no invasive head frame is needed — unlike older radiosurgery systems.
Frameless · single or few sessionsOrgan-confined prostate cancer is treated in around five sessions. Gold fiducials and, where used, a protective spacer help target the prostate precisely while sparing the bladder and rectum.
~5 sessions · gland-sparingEarly-stage and inoperable lung cancers, and lung metastases. Real-time motion tracking follows the tumour as you breathe — a major advantage where the chest constantly moves.
Breath-synchronised trackingPrimary liver cancer, liver metastases, and pancreatic tumours — often in patients who are not surgical candidates. Fiducial tracking handles the movement of these abdominal organs.
For inoperable / complex casesTumours on or near the spinal cord, where even a millimetre matters. The vertebral anatomy is tracked directly, allowing high, safe doses close to the cord.
Cord-sparing precisionA non-tumour use: for this intensely painful facial-nerve condition, a focused dose to the trigeminal nerve can relieve pain when medication has failed — without any open surgery.
Functional · pain reliefHead and neck tumours, skull-base lesions, and arteriovenous malformations (AVMs) in the brain — delicate areas surrounded by critical structures where pinpoint targeting is essential.
Delicate, high-stakes sitesA small number of metastases (oligometastatic disease) and selected kidney tumours can be ablated with CyberKnife, often alongside chemotherapy or other treatment, to gain strong local control.
Targeted local controlIt is not a replacement for every cancer treatment — but in the right cases it offers something no other option can. Here are the typical indications. Green is a strong fit, amber needs case-by-case review, red is usually not suitable.
Compact tumours with clear edges are ideal targets for high-precision radiosurgery.
Targets too deep or too close to vital structures for safe open surgery.
Patients whose age or other health problems make general anaesthesia and surgery too risky.
Cancer that has returned after previous radiation — CyberKnife can often re-treat where broad beams cannot.
Metastases, meningiomas, acoustic neuromas, and tumours beside the spinal cord.
Organ-confined disease treated in around five sessions instead of weeks of daily radiation.
A limited number of metastases that can be targeted to gain strong local control.
When an eligible patient simply wishes to avoid an incision, anaesthesia and a hospital stay.
Severe facial-nerve pain unresponsive to medication — a focused, non-surgical option.
Larger lesions may be treated, but suitability depends on location and proximity to organs — reviewed case by case.
Often treatable thanks to precision, but dose limits to nearby structures must be checked carefully.
Very large tumours or widely disseminated cancer are usually better suited to surgery, systemic therapy, or conventional radiation.
CyberKnife offers remarkable advantages, but no treatment is right for everyone or without side effects. Here is what to genuinely expect, in plain language.
CyberKnife is one of the shortest cancer-treatment journeys there is — most international patients are in India for only one to two weeks. Here is the standard timeline.

These patients chose CyberKnife when surgery was risky, when conventional radiation felt impossible, or when the cost abroad was simply out of reach. Start your story →
"A small brain tumour, and three surgeons too nervous to operate near it. Medifly arranged CyberKnife in Chennai — three sessions, no cut, no anaesthesia. I walked out each day and went sightseeing. A year on, my scans are stable and I feel completely myself."
"Early prostate cancer at 64. My US quote for CyberKnife was over $40,000 and my insurance fought me on it. Medifly arranged the same five-session treatment in India for $7,200. Back at work within days. PSA is right where my doctor wants it."
"I'm from Patna. A lung tumour that moved with every breath — my local centre couldn't target it. Medifly's team in Chennai used CyberKnife with breathing tracking. Four sessions, fully outpatient. Six months later the tumour has shrunk and I'm breathing easy. ₹5.4 lakh, all in."
"A spinal tumour pressing close to the cord. Surgery felt terrifying. The Chennai radiosurgery team had treated hundreds of spine cases — CyberKnife in two sessions. The pain eased within weeks. Total cost was a fraction of the Dubai quote, including our accommodation."
"My cancer returned after radiation years ago, and I was told it couldn't be re-irradiated. Medifly's specialist disagreed — CyberKnife was precise enough. One focused course. My follow-up scans are clean and I am living my life again. The coordinator checked on me daily."
"Years of trigeminal neuralgia — the pain was unbearable and medication had stopped working. The NHS wait was long and surgery scared me. Medifly arranged CyberKnife to the nerve in Chennai. The relief, over the following weeks, changed my life. The team still keep in touch with my GP."
According to the World Health Organization ↗, cancer is among the leading causes of death worldwide — and precise, tissue-sparing radiosurgery has become a key tool for treating tumours that are inoperable or difficult to reach.
You have been told surgery is too risky or impossible because of the tumour's location. CyberKnife can often reach and treat targets a surgeon cannot, with no incision at all.
Your cancer has returned and you have been told it cannot be re-irradiated. CyberKnife's precision makes re-treatment possible in many such cases.
If you have been quoted $35,000–$95,000 in the US, around £22,000 in the UK, or a very high figure in the UAE, India offers the same Accuray platform at $5,500–$8,500 all-inclusive.
If radiosurgery in your country involves months of waiting, that delay can be agonising. Medifly typically arranges the full pathway within one to two weeks.
If you are eligible and simply wish to avoid an incision, general anaesthesia and a hospital admission, CyberKnife offers a powerful, outpatient alternative.
If your city or country has no CyberKnife facility or limited radiosurgery expertise, Medifly arranges your full pathway in Chennai — from consultation through treatment to follow-up.
