Proton therapy is a form of radiation treatment that uses charged particles instead of X-rays. Because a proton beam deposits most of its energy at a set depth and then stops, it can target a tumour precisely while sparing more of the surrounding healthy tissue.

Precision matters where millimetres count. See which tumours proton therapy treats best.
From the first WhatsApp message to follow-up scans back home.
Diagnostic MRI or CT, PET-CT if done, biopsy or histopathology report, and any previous radiotherapy records including the dose and dates. Photographs of paper reports on WhatsApp are perfectly fine.
A proton radiation oncologist tells you honestly whether protons will help in your case, or whether modern IMRT, SBRT or surgery would give you the same result for far less. Many patients are told they do not need protons.
Site, technique, number of fractions, anaesthesia, stay and travel priced end to end in one itemised document, with the hospital invitation letter for a medical visa usually issued in 2–4 hours.
e-Medical Visa approved in 24–48 hours for all countries; regular medical visa in 2–5 working days. Attendant visas for family are arranged at the same time, along with accommodation near the centre.
A planning CT in the exact treatment position, with a thermoplastic mask for head sites or a vacuum cradle for the body, plus MRI or PET fusion. Fiducial markers or a rectal spacer are placed on this visit if needed.
The team builds a pencil beam scanning plan, stress-tests it against setup and range uncertainty, and puts it side by side with an X-ray plan. You are shown both dose maps before anything is signed off.
Each session takes 15–45 minutes with only a minute or two of beam time, and is completely painless. Sessions run daily on weekdays; children are treated under short general anaesthesia in the morning slots.
Weight, skin, mucosa and blood counts are checked, and a verification CT confirms the Bragg peak is still landing where it was planned. The plan is re-optimised if your anatomy has changed.
You leave with a full dosimetric record, a written late-effects surveillance schedule, and medication for recovery. Most patients fly home within 2–4 days of the last session.
Response scans at around 3 months and then at set intervals, read remotely by the same proton oncologist and discussed with you on WhatsApp in your own language.
Pick the site being treated. Everything on this page — the beam simulator, the organ-sparing meter, the honest benefit verdict and the cost planner — updates to that cancer.
The biggest quality-of-life gain of any adult site: markedly less severe mucositis, far fewer feeding tubes and measurably more saliva a year later, because the beam never crosses to the opposite side of the mouth.
Organs the beam is designed to spare
Typical planning-study values, not your plan. Your real sparing is measured on your own comparative dose–volume histogram, which we send you before treatment is agreed.
Honest benefit verdict
This is a site where protons change outcomes, not just dose maps. Most international tumour boards would recommend them, and many insurers cover them here without argument.
Ask about head & neck / nasopharynxNext: watch the proton beam physically stop inside the tumour
Move the tumour deeper, make it thicker, change the X-ray energy — and see exactly how much radiation an X-ray beam leaves in the tissue behind your cancer that a proton beam does not.
Healthy tissue outside the tumour
less total radiation with protons in this geometry
X-ray exit dose
About 32% of the peak dose is still being delivered as the beam leaves the far side of the body — into the heart, bowel, cord or opposite lung, depending on where you point it.
Proton exit dose
Zero. The protons run out of energy at 8.0 cm and stop. There is no beam beyond the tumour to spare anything from.
Illustrative physics model for education. Real percentage depth-dose curves depend on beam energy, field size, tissue heterogeneity and the number of fields used.
Not every proton centre offers every technique, and the one you need depends on whether your tumour moves and how much your body will change during the course.

Next: what it actually costs, session by session
Choose the tumour site, the technique and the number of sessions. Your exact figure comes back within 1 hour of a proton oncologist seeing the scans.
Typical for this site: 33 sessions · about 7 weeks in the country
Estimated all-inclusive course
Roughly $993 per session across 33 sessions, including planning, imaging, physics and on-treatment care.
Your calendar in the country
33 weekday sessions ≈ 7 weeks of treatment, plus about 1 week beforehand for consultation, simulation and planning.
Every proton package includes
Indicative ranges only. The final figure depends on the number of fractions, whether anaesthesia, gating or adaptive re-planning are needed, concurrent chemotherapy, and length of stay. We send an itemised written estimate before you travel — no charge, no obligation.
Proton therapy is not a stronger radiation. It is the same biological dose placed more precisely. That precision buys fewer side effects, the ability to treat tumours that were previously untreatable, and in children a genuinely different lifetime risk profile — but for many common cancers the cure rate is the same as modern X-ray therapy, and any honest centre will tell you so.
Next: proton vs IMRT vs SBRT — the comparison nobody selling protons shows you
We sell none of these. This is what a radiation oncologist would tell you across a desk.
If IMRT or SBRT would give you the same result, we will say so — and arrange that instead, at a fraction of the cost. That conversation is free either way.
A proton stops inside you and leaves nothing behind. You can hug your children, share a bed and travel on a plane the same day. This is completely different from radioactive seed or isotope therapy.
Fatigue, skin redness and site-specific soreness usually start in week 2–3, peak in the last week and settle over 4–8 weeks after the course ends. The low-dose sparing shows up as fewer of these, not none.
Protons are range-sensitive: losing 5 kg during a head and neck or abdominal course physically shifts where the Bragg peak lands. Nutrition support is part of treatment, not an optional extra.
If cancer ever recurs, whether you can be re-irradiated depends on exactly which organ received what dose. Keep the DICOM plan and dose–volume histogram safe — we archive a copy of yours too.
No forms, no payment, no obligation. A proton radiation oncologist reviews your scans, compares a proton plan against standard radiotherapy, and tells you honestly whether the difference is worth travelling for.
We reply on WhatsApp within 1 hour. Your scans and reports are never shared with anyone else.
"Our daughter was six. They showed us the X-ray plan and the proton plan side by side and we could see the difference on her little brain. Thirty sessions, she never lost her hearing."
"Nasopharynx cancer. I was warned about a feeding tube and never needed one. I was eating rice through the last week of treatment."
"The tumour came back where they had already given radiation five years ago. Two hospitals said nothing more could be done. Protons treated it."
An X-ray beam gives its highest dose just under the skin and then keeps going, depositing radiation through the tumour and out the other side of the body. A proton is a heavy charged particle: it travels quietly through tissue, then dumps almost all of its energy in one sharp burst at a depth the physicist chooses — the Bragg peak — and stops dead. Nothing continues beyond it. In practice that means the tumour can receive the same or a higher dose while the heart behind a lung tumour, the brainstem behind a skull-base tumour, the bowel in front of a prostate, or a child's growing spine receive far less. Modern pencil beam scanning paints the tumour spot by spot in three dimensions, so the high-dose region wraps around concave targets that X-rays cannot spare.
A proton course can run from one week to eight, so the paperwork has to cover the patient and at least one attendant for the whole stay. We arrange it together, and long-stay accommodation within walking distance of the centre.
