Protons stop inside the tumour. That single physical property changes the equation for cancers near critical organs.
Proton therapy is the most precise form of external beam radiation available. Unlike conventional photon radiation, which deposits dose before, within, and beyond the tumour, protons deliver their energy at a defined depth and then stop — virtually eliminating exit dose to healthy tissue. Thailand operates one of the few proton centres in Asia, making it a destination for patients who need this technology but face long waits or prohibitive costs at home.

Proton therapy uses accelerated proton particles to destroy cancer cells with a level of spatial precision that conventional radiation cannot match. The Bragg peak — the point where protons deposit their maximum energy — can be placed precisely within the tumour volume, delivering therapeutic dose to cancer cells while dramatically reducing radiation to adjacent healthy organs.
This matters most when the tumour sits near structures that cannot tolerate radiation damage — the brain, spinal cord, optic nerves, heart, or developing tissues in children. Thailand's proton centres are equipped with pencil beam scanning, robotic patient positioning, and image-guided verification to ensure sub-millimetre accuracy at every session.
Proton therapy centres are scarce worldwide. Thailand's centre is one of the few in Asia with pencil beam scanning capability, and it operates without the multi-month waiting lists common at European and US facilities.
Pencil Beam
Latest Scanning Technology
Thailand's proton centre uses pencil beam scanning — the most advanced delivery method — painting the tumour layer by layer with sub-millimetre accuracy and intensity modulation.

Patients from across Asia, the Middle East, and Oceania travel to Thailand for proton therapy. The centre is experienced in managing international patients through multi-week treatment courses.
We do not charge for our service — you pay the treatment centre directly with no markup. Proton therapy is expensive everywhere, but Thailand offers it at a fraction of Western prices.
Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
A full course of proton therapy in Thailand typically costs between $15,000 and $27,000. The wide range reflects the number of treatment fractions, tumour complexity, and whether intensity-modulated planning is required. Shorter hypofractionated courses sit at the lower end.
The radiation oncologist's fee covers treatment planning, on-treatment reviews, and clinical oversight. Medical physics charges include dosimetry, plan optimisation, and quality assurance. Facility fees cover the cyclotron, treatment-room time, and daily imaging verification. Coordinator support is included throughout.
The number of fractions is the main cost driver — a 30-fraction course costs more than a 5-fraction hypofractionated plan. IMPT planning adds complexity and physics time. Paediatric cases requiring sedation or anaesthesia for each session incur additional charges. Treatment site complexity also influences planning costs.
Typical ranges at our partner centre:
Final pricing is confirmed after planning CT and treatment design.
Proton therapy in Thailand costs 50 to 70 percent less than equivalent treatment in the US ($45,000–$90,000), Australia (A$37,500–A$75,000), and UK (£33,000–£67,500). For a treatment that can cost over $100,000 privately in some countries, the difference is transformative.
The treatment intent and clinical indication determine the approach. Proton therapy's advantages are most pronounced where conventional radiation would expose healthy tissue to unacceptable dose.
Used as the primary cancer treatment when proton precision offers a meaningful dosimetric advantage over photon radiation. Standard for paediatric brain tumours, skull base chordomas, and eye cancers where sparing surrounding tissue directly affects long-term function and quality of life.
Delivered after surgical resection to reduce local recurrence risk. Proton precision matters when the tumour bed sits near critical structures — post-operative radiotherapy to the brain, spine, or mediastinum benefits from reduced exit dose to the heart, lungs, or spinal cord.
Children are the patient group with the strongest evidence base for proton therapy. Their developing tissues are highly radiation-sensitive, and the reduced dose to healthy organs lowers the risk of growth impairment, endocrine dysfunction, cognitive effects, and radiation-induced secondary cancers later in life.
The delivery method is selected based on the tumour's shape, depth, motion characteristics, and proximity to organs at risk. Here is what is available at our partner centre.
The most advanced proton delivery method. A narrow beam is steered magnetically to paint the tumour layer by layer, with each layer corresponding to a specific depth. Dose intensity varies across thousands of individual spots, conforming precisely to irregular tumour shapes and enabling intensity-modulated proton therapy.
An advanced application of pencil beam scanning where computer algorithms optimise dose delivery across multiple beam angles simultaneously. Each spot's intensity is adjusted to maximise tumour coverage while further reducing dose to organs at risk. Represents the most advanced approach currently available in proton treatment planning.
Proton therapy demands higher positional accuracy than photon treatment because the Bragg peak depth is sensitive to tissue density changes. Cone-beam CT, orthogonal X-ray verification, and robotic couch adjustments ensure the patient is positioned to sub-millimetre precision before every fraction. Motion management is applied for thoracic and abdominal targets.
Each daily session is painless and lasts 15 to 45 minutes including positioning and imaging. You remain fully alert and can return to normal activities immediately. Most patients maintain light daily routines — walking, reading, working remotely — throughout the treatment course.
Mild fatigue is the most common side effect and usually peaks in the first week after your final session. Localised skin changes may be present in the treatment area. Your clinical team reviews early recovery and provides symptom management guidance.
Fatigue gradually improves and any skin redness begins to settle. Follow-up imaging and blood work are arranged to assess initial treatment response. Most patients feel well enough to consider travel home during this period.
Energy levels approach baseline and acute side effects resolve for most patients. A comprehensive follow-up confirms treatment response and establishes a long-term surveillance plan. Your oncologist coordinates ongoing monitoring with your home medical team.
Most courses run five days per week for four to eight weeks depending on the cancer type and dose prescription. Each session is 15 to 45 minutes. Your radiation oncologist confirms the exact fraction count during initial planning. Allow additional time for the planning CT and simulation before treatment begins.
Most patients travel home within one to two weeks of their final session, once a post-treatment review confirms recovery is on track. Fatigue may persist for several weeks but does not prevent travel. Your team provides a fitness-to-fly recommendation.
Your radiation oncologist provides a detailed surveillance plan including imaging intervals and clinical review schedules for your home team. For paediatric patients, long-term developmental monitoring is arranged. Remote consultations with your Thai oncologist remain available.
Proton therapy carries fewer side effects than conventional radiation because less healthy tissue is exposed. Side effects are generally mild and confined to the treatment area.
Pre-treatment assessment includes diagnostic imaging, blood work, and review of any prior radiation exposure. Your radiation oncologist explains your individual risk profile and anticipated side effects before treatment begins.
Yes. Thailand's proton therapy centre operates to the same safety, quality assurance, and equipment calibration standards as major international facilities. Treatment plans undergo independent physics verification before the first fraction. The centre holds international accreditation and reports outcomes in line with published international data.
The principal advantage is reduced radiation to healthy tissue. For tumours near the brain, spinal cord, heart, or developing tissues in children, this translates to fewer acute side effects and lower risk of late complications. Tumour control rates are comparable to photon therapy — the benefit is in what is spared, not in the dose to the tumour itself.
Proton therapy is not suitable for all cancers. Widespread metastatic disease, haematological cancers, and some tumour locations may not benefit from the dosimetric advantage. Your radiation oncologist will advise honestly whether proton therapy offers a genuine clinical benefit over conventional treatment for your specific case.
Proton therapy requires a specialist team — radiation oncologists with proton-specific training, dedicated medical physicists, and purpose-built infrastructure. Here is what our partner centre offers.
Our partner centre operates a cyclotron-based proton therapy system with pencil beam scanning, robotic patient positioning, and cone-beam CT verification. It is one of the few centres in Southeast Asia with this capability, treating patients from across the region and beyond.
The radiation oncologists at our partner centre have proton-specific clinical training and treat a high volume of cases annually. Many trained at established proton centres in the US, Japan, or Europe before joining Thailand's programme. They work alongside a medical physics team that verifies every treatment plan.
Pencil beam scanning capability is essential — older passive scattering systems are less precise. Confirm the centre has experience treating your tumour type with proton therapy. Ask about their quality assurance process and whether treatment plans undergo independent physics review. Centre volume matters in proton therapy more than most treatments.
Proton therapy results are measured through imaging response and, critically, through the side effects that did not occur because healthy tissue was spared.
Tumour control rates with proton therapy are comparable to conventional photon radiation — the clinical advantage lies in reduced collateral damage. Paediatric patients show lower rates of growth impairment, cognitive effects, and secondary cancers. Adult patients near critical structures experience fewer acute and late side effects.
Follow-up imaging assesses tumour response over weeks and months after treatment. Your radiation oncologist reviews results and establishes a long-term monitoring schedule. For paediatric patients, developmental milestones and endocrine function are tracked as part of ongoing surveillance.
A proton therapy course requires a stay of several weeks. Planning ahead for accommodation and daily logistics makes the experience considerably smoother.
Plan for four to eight weeks. This covers the planning CT and simulation in the first few days, the full treatment course of daily sessions, and a post-treatment review. Shorter hypofractionated courses may require only two to three weeks. Your coordinator provides a personalised timeline once your fraction count is confirmed.
Your quote covers the radiation oncologist, medical physics team, all treatment sessions, daily imaging verification, pre-treatment diagnostics, supportive care, and coordinator support. Accommodation near the treatment centre and flights are arranged separately, with coordinator assistance.
Treatment sessions are short — most patients finish within 45 minutes and have the rest of the day free. Many international patients work remotely, explore Bangkok, or rest at their accommodation. Your coordinator helps arrange comfortable serviced apartments close to the centre.
