Proton Therapy in India — Availability, Cost and Waiting Time

Medically reviewed by Dr. Venkata Sushma P, Radiation Oncologist, MBBS · MD (Radiation Oncology) · Last reviewed August 2026

Proton therapy isn't automatically the "stronger" option — its real advantage is indication-specific, and it's available in India at only a handful of specialised centres. This page covers the logistics you actually need: where it's offered, an indicative cost range, and how insurance and waiting times typically work, referencing ASTRO model policy guidance throughout.

  • Not automatically better — proton therapy's benefit is indication-specific, not a general upgrade over modern conventional radiotherapy.
  • Limited availability — a small number of centres nationwide, which usually means travel and a temporary stay.
  • Real, dated cost range — an indicative figure as of August 2026, not a marketing number.
  • Insurance varies — coverage depends on your specific policy; we help you check before you commit.

Where is proton therapy available in India?

Proton therapy is available in India only at a small number of specialised centres, because it needs a large, purpose-built facility that most cancer hospitals — including CION's own partner network — do not have. As of August 2026, dedicated proton centres remain concentrated in a few major metro cities, and total capacity nationwide is still limited compared with conventional radiotherapy, which is delivered at NABH-accredited centres far more widely.

CION does not own or operate a proton facility — no single hospital group in India owns every radiotherapy technology. What CION can do is review your reports, give you a direct opinion on whether proton therapy is likely to add real benefit for your specific cancer, and coordinate a referral to a specialised centre when it's appropriate.

Coordinating care for a family member from another city or from abroad? Most patients relocate temporarily near the centre for the full course — factor that into your planning early, not after you've already scheduled.

Did you know?

Proton therapy’s physical advantage is called the Bragg peak — protons deposit most of their energy at a set depth in tissue and then stop, unlike photon (X-ray) beams, which continue through tissue beyond the tumour. ASTRO’s model policy guidance recognises clear, evidence-based benefit for specific cancers such as certain paediatric tumours, skull-base and ocular cancers — while for many common adult cancers, evidence of added benefit over modern conventional techniques is still developing.

Cost, plainly

What does proton therapy cost in India?

Indicative cost, as of August 2026: a full course of proton therapy in India commonly ranges from roughly ₹20 lakh to ₹35 lakh, though this is a broad range, not a quote. The final figure depends on your cancer type and site, the number of fractions your plan needs, planning and simulation charges, and whether you need extended inpatient or outpatient stay near the centre.

If you're travelling from another city or country, add realistic travel and accommodation costs to whatever estimate a centre gives you before you compare it with other treatment options.

Before you get a quote

What drives the cost up or down

Use this to ask sharper questions when a centre gives you an estimate — not to predict your own number.

  • Number of fractions — more treatment sessions generally mean a higher total cost; your fraction count depends on your cancer type and stage, decided by your tumour board.
  • Cancer type and site — complex tumour locations that need more precise planning typically cost more than simpler, more accessible sites.
  • Planning and simulation — detailed imaging and dose simulation before treatment starts is usually billed separately from the sessions themselves.
  • Travel and accommodation — since proton centres are limited to a few cities, most patients and a caregiver relocate temporarily; factor this into your real-world total.
  • Centre-specific pricing — each specialised centre sets its own charges; get a written, itemised estimate directly rather than relying on a general range.

All figures above are indicative, as of August 2026, and will vary by centre and individual treatment plan.

Before you commit

Is proton therapy covered by insurance in India?

Coverage varies widely by insurer and policy. Many standard retail health insurance plans in India exclude or cap proton therapy, while some higher-tier and corporate covers include it, usually with a pre-authorisation process. Aarogyasri and CGHS coverage for proton therapy is limited and evaluated case by case, not guaranteed.

Always get your policy's exact terms confirmed in writing by your insurer and the treating centre's billing team before you schedule anything, so there are no surprises partway through a course of treatment. CION's team can help you read your policy documents and know which questions to ask.

Timing matters too

How long is the waiting time for proton therapy in India?

Waiting times vary by centre, current caseload and how urgent your case is. Because only a small number of proton centres exist nationwide, scheduling windows can be longer than for widely available techniques like IMRT or SBRT, especially for non-urgent cases.

Ask the specific centre directly for its current wait once your reports are ready, and discuss with your tumour board whether any delay affects your treatment goals — for some cancers timing matters more than for others.

Proton therapy vs conventional (photon) radiotherapy

A general comparison to help you ask sharper questions — not a personal recommendation. Your tumour board decides what fits your specific cancer.

Factor Conventional radiotherapy (IMRT/VMAT) Proton therapy
What it delivers High-energy X-ray (photon) beams Proton particle beams
How the dose behaves Continues through tissue beyond the tumour, at a lower dose Deposits most energy at a set depth, then stops (the "Bragg peak")
Availability in India Delivered at NABH-accredited centres across most major cities Available at a small number of specialised centres nationwide
Typical candidates A wide range of adult and paediatric cancers Select cases — certain paediatric, skull-base, ocular and re-irradiation cases where sparing nearby tissue matters most
Indicative cost* Typically lower; varies by technique and course length Typically higher — commonly ₹20–35 lakh for a full course
Evidence base Backed by decades of NCCN/ASTRO-aligned clinical use Growing evidence for specific indications; ASTRO model policies guide which cancers show clear added benefit
Who decides Your tumour board, based on tumour site, stage and goals Your tumour board, based on tumour site, stage and goals

*Cost figures are indicative, as of August 2026, and vary by centre and treatment plan.

Logistics, not a sales pitch

How CION helps you evaluate proton therapy

1

Review your reports and staging

Share your diagnosis, imaging and pathology reports; a radiation oncologist reviews them before any recommendation is made.

2

Discuss whether proton adds real benefit for your case

You get a direct, indication-specific opinion — not a blanket recommendation — on whether proton therapy is likely to help more than a conventional technique for your specific cancer.

3

Explain the realistic logistics

Indicative cost, typical insurance coverage, and what travel and stay near a centre would actually involve — explained plainly before you decide.

4

Coordinate a referral, where appropriate

If proton therapy fits your case, CION helps coordinate your referral to a specialised centre and keeps your local oncology team informed.

5

Present the NABH-accredited alternative

If a conventional technique is equally appropriate for your cancer, CION coordinates that treatment at an NABH-accredited partner centre closer to home — without the added cost and travel.

Want an Honest Second Opinion on Proton Therapy?

Bring your reports and get a direct, written second opinion on whether proton therapy is likely to help your specific cancer — before you travel or spend on it. Free, confidential, no commitment to start treatment.

Indication-specific, not universal

Who proton therapy typically suits

This is general guidance, not a diagnosis of your own case — only your tumour board can say what applies to you.

Selected cases

Paediatric cancers

Sparing healthy, still-developing tissue near a tumour matters more in a growing child; several paediatric protocols consider proton therapy for specific tumour types and stages.

Selected cases

Skull-base and ocular tumours

Where a tumour sits close to the brainstem, optic nerve or eye, proton therapy's sharper dose fall-off can help spare structures that are hard to protect with conventional beams.

Selected cases

Re-irradiation

When a patient needs radiation again in an area already treated once, limiting extra dose to that tissue becomes more important — one situation where proton therapy is often considered.

Most patients

Many other adult cancers

For many common adult cancers, modern conventional radiotherapy — IMRT, VMAT, SBRT — delivers comparably effective, well-established results without the added travel and cost.

Common questions

Proton therapy in India — your questions answered

Where is proton therapy available in India?

Proton therapy is available in India only at a small number of specialised centres, because it needs a large, purpose-built facility that most cancer hospitals — including CION's own partner network — do not have. As of August 2026, dedicated proton centres remain concentrated in a few major metro cities, and total capacity nationwide is still limited compared with conventional radiotherapy, which is far more widely available. If you're coordinating care from another city or from abroad for a family member, factor in travel and a stay near the centre, since most patients relocate temporarily for the full course.

What does proton therapy cost in India?

Indicative cost, as of August 2026: a full course of proton therapy in India commonly ranges from roughly ₹20 lakh to ₹35 lakh, though this is a broad range, not a quote. The final figure depends on your cancer type and site, the number of fractions your plan needs, simulation and planning charges, and whether you need extended inpatient or outpatient stay near the centre. If you're travelling from another city, add realistic travel and accommodation costs to whatever estimate a centre gives you before you compare it with other treatment options.

Is proton therapy covered by insurance in India?

Coverage varies widely by insurer and policy. Many standard retail health insurance plans in India exclude or cap proton therapy, while some higher-tier and corporate covers include it, usually with a pre-authorisation process. Aarogyasri and CGHS coverage for proton therapy is limited and evaluated case by case, not guaranteed. Always get your policy's exact terms confirmed in writing by your insurer and the treating centre's billing team before you schedule anything, so there are no surprises partway through a course of treatment.

Is proton therapy always better than conventional radiotherapy?

No, not automatically. Proton therapy's physical advantage — depositing most of its energy at a set depth and then stopping — gives it a genuine benefit for select cancers, particularly certain paediatric tumours, skull-base and ocular cancers, and some re-irradiation cases where sparing nearby healthy tissue matters most. For many common adult cancers, modern conventional techniques such as IMRT and VMAT deliver comparably effective, well-established results, and evidence of added benefit from proton therapy over these techniques is still developing for several indications. Whether it adds meaningful value for your specific cancer is a question for your tumour board, not a general rule.

How long is the waiting time for proton therapy in India?

Waiting times vary by centre, current caseload and how urgent your case is. Because only a small number of proton centres exist nationwide, scheduling windows can be longer than for widely available techniques like IMRT or SBRT, especially for non-urgent cases. Ask the specific centre directly for its current wait once your reports are ready, and discuss with your tumour board whether any delay affects your treatment goals — for some cancers timing matters more than for others.

Does CION offer proton therapy directly?

No. CION Cancer Clinics does not own or operate a proton therapy facility, a linear accelerator, CyberKnife or Gamma Knife — no single hospital group in India owns every radiotherapy technology. What CION does is review your reports and staging, give you a direct opinion on whether proton therapy is likely to add meaningful benefit for your specific cancer, explain realistic cost, insurance and travel logistics, and coordinate a referral to a specialised proton centre when it's appropriate — or explain the conventional, NABH-accredited partner-centre alternatives when it isn't.

This page explains general availability, cost and insurance logistics for proton therapy in India; it is not a substitute for guidance from your own oncology team about your specific diagnosis, staging and treatment plan.
