The short answer

CyberKnife surgery in India costs between $4,500 and $9,000, against $30,000 to $60,000 in the US and Europe. It is a robotic radiosurgery system that delivers highly focused radiation to tumours anywhere in the body, from the brain to the spine, lung, liver and prostate, over just 1 to 5 sessions and without any incision.

About CyberKnife Surgery (Robotic Radiosurgery)

CyberKnife is a robotic radiosurgery system that delivers precisely focused radiation to tumours anywhere in the body, using a linear accelerator mounted on a robotic arm that moves around the patient with sub-millimetre accuracy. Despite the name, no cutting or incision is involved; it is a form of radiation therapy, not surgery in the traditional sense.

What sets CyberKnife apart

Unlike Gamma Knife, which is used specifically for conditions in the brain, CyberKnife can treat tumours throughout the body, including the brain, spine, lung, liver, pancreas and prostate. Its robotic arm continuously tracks the target in real time, adjusting for natural movement such as breathing, which allows it to treat tumours in areas that move, something older radiosurgery systems could not do as precisely. Most treatments do not require the rigid head frame used in some other radiosurgery systems, using a lightweight mask or no fixation device at all for body treatments.

Fewer, higher-dose sessions

CyberKnife typically delivers treatment over just 1 to 5 sessions, compared to the several weeks of daily sessions used in conventional radiotherapy, by giving a higher, more precisely targeted dose per session. This approach, called stereotactic body radiation therapy (SBRT) when used outside the brain, shortens the overall treatment timeline considerably while maintaining strong local tumour control.

Who it is used for

CyberKnife is often recommended for patients whose tumours are considered inoperable or high-risk for conventional surgery due to location or the patient's overall health, as well as for patients seeking a non-invasive alternative. It is commonly used for early-stage lung cancer, localised prostate cancer, spinal tumours, liver tumours, and brain metastases, among other conditions. Your radiation oncologist confirms suitability based on the size, number and location of your tumour(s).

Why patients choose India for this

Save 70-85% on the same Accuray CyberKnife system

Partner hospitals use the same Accuray-certified CyberKnife systems used at leading centres in the US and Europe, at a fraction of the cost.

Partner hospitals use the same Accuray-certified CyberKnife systems used at leading centres in the US and Europe, at a fraction of the cost.

Where a tumour sits in the lung, liver, spine or prostate rather than the brain, CyberKnife's whole-body capability and real-time motion tracking make it the more relevant radiosurgery option, and our partner centres are equipped for exactly this range.

Fewer sessions, shorter time in India

Because most CyberKnife courses are completed in 1-5 sessions rather than weeks of daily treatment, the total time needed in India is far shorter than for conventional radiotherapy.

Radiation oncology teams with real robotic radiosurgery experience

Partner hospitals run dedicated CyberKnife programs with radiation oncologists and medical physicists experienced specifically in this technology, not general radiotherapy departments offering it occasionally.

How CyberKnife Surgery (Robotic Radiosurgery) is done

  1. Consultation and reviewA radiation oncologist reviews your scans and diagnosis remotely to confirm whether CyberKnife is a suitable option for your tumour's size, location and number.
  2. Pre-treatment imagingOn arrival, CT or MRI imaging maps the exact target, and small markers may be placed near the tumour in certain cases to help the robotic arm track it precisely.
  3. Treatment planningThe team calculates the exact radiation dose, angles and number of sessions needed, tailored to your specific tumour.
  4. Treatment session(s)You lie comfortably while the robotic arm delivers radiation from multiple angles, continuously tracking the target and adjusting for movement such as breathing.
  5. Repeat sessions if plannedIf your plan involves multiple sessions, these are usually given on consecutive or near-consecutive days.
  6. Post-treatment reviewYour radiation oncologist reviews how the treatment went and confirms a follow-up imaging schedule.
  7. DischargeYou go home the same day as each session, with no hospital admission required, and a plan for follow-up imaging over the following months.

Recovery and what to expect

  • Day of each sessionMost patients feel normal immediately afterward and can resume light activity the same day.
  • First few daysMild, localised side effects may occur depending on the treatment site, such as fatigue or site-specific symptoms, and are generally short-lived.
  • 1-2 weeksMost patients have returned to normal daily activity by this point.
  • 6-12 weeksFollow-up imaging typically assesses how the treated tumour has responded, since CyberKnife's effects develop over time rather than immediately.
  • OngoingPeriodic follow-up imaging continues over the following months, coordinated with your home oncology team, to confirm long-term local control.

Where it is done

Frequently asked questions

Is CyberKnife actual surgery?
No, despite the name, there is no incision or cutting involved. It is an advanced form of radiation therapy delivered through a robotic arm.
How is CyberKnife different from Gamma Knife?
Gamma Knife treats conditions in the brain only. CyberKnife can treat tumours throughout the body, including the lung, liver, spine and prostate, and its robotic arm tracks tumour movement in real time.
How many sessions will I need?
Most treatment plans involve 1 to 5 sessions, though this depends on your tumour's size, location and type. Your radiation oncologist confirms the exact number during planning.
Is CyberKnife painful?
No. Sessions are painless, and no anaesthesia is required. You lie still while the machine delivers treatment around you.
How long do I need to stay in India?
Around 5-10 days in total, covering pre-treatment imaging, the sessions themselves, and a review before you travel home.
Is CyberKnife suitable for tumours that move, like in the lung?
Yes. Its real-time tracking system is specifically designed to adjust for movement such as breathing, which is one of its key advantages over some other radiosurgery systems.
Why is CyberKnife so much cheaper in India than in my home country?
Lower hospital overheads and staffing costs bring the price down significantly. The CyberKnife technology itself is the same Accuray-certified system used at leading centres internationally.
