Start With the Treatment Target, Not the Technology
The first question is not whether proton therapy exists in China. It is what the treating team would actually irradiate, and why. Proton therapy is a form of radiotherapy, so the clinical logic follows the same path as any radiation decision: what is the target, what is nearby, what dose is needed, and what has already been tried.
Ask the clinician to state the target in plain terms. Is it a tumour, a tumour bed after surgery, a lymph node region, or something else? Is the goal curative, adjuvant, or palliative? Has the diagnosis been confirmed by pathology, and has staging been completed? These answers determine whether proton therapy is even a relevant question.
A useful phrase is: "Please describe the exact target you would treat, the dose you would aim for, and the normal tissues you would try to avoid." This keeps the conversation clinical rather than promotional. It also gives you a record you can compare if you seek another opinion.
If the team cannot name the target or says more imaging is needed first, that is not a refusal. It is a signal that the assessment is still at an early stage. Ask what specific information is missing and who will provide it.
Ask About Risks in Terms of Your Own Anatomy
Proton therapy is not risk-free simply because it uses protons rather than X-rays. The clinical distinction to discuss with your treating team is that proton therapy is radiotherapy delivered with protons, and that not every patient benefits. Suitability is assessed individually. That means the risk conversation must be individual too.
Ask the clinician to compare the proposed proton plan with the best available alternative for your case. The alternative might be photon radiotherapy, surgery, systemic therapy, surveillance, or a combination. Ask what the expected difference is in dose to nearby organs, and what that difference could mean for side effects.
Do not accept a general statement that proton therapy has fewer side effects. Ask: fewer side effects where, for which organ, over what time frame, and based on what evidence? If the clinician cannot answer for your specific anatomy, ask for a review of your imaging before a recommendation is made.
You can also ask about uncertainty. A responsible clinician can discuss evidence-based risk estimates and the limits of those estimates without guaranteeing an individual outcome. Ask what is known, what is uncertain, and what would change the plan.
Alternatives: Make the Comparison Explicit
A recommendation for proton therapy should come with a comparison, not just a description. Ask the team to list the alternatives they considered and why each was set aside. If the alternative is standard radiotherapy, ask how the proton plan differs in target coverage and in dose to nearby structures. If the alternative is surgery, ask whether proton therapy would be used before or after an operation, or instead of it. If the alternative is systemic treatment, ask how radiotherapy would fit with that plan. These are not challenges to the clinician. They are the questions that make consent meaningful.
Ask the team to be specific about what each option would involve for you. How many hospital visits would surgery require, and what recovery would it demand? How many radiotherapy sessions would each plan involve? What monitoring would surveillance require, and how often? A comparison in these practical terms is easier to weigh than a general statement that one option is better.
Ask whether a multidisciplinary review has taken place. Complex cases may benefit from input from more than one specialty, and the treating team should be able to say who has reviewed your imaging and pathology. If no such review has occurred, ask whether one is appropriate and what it would add. If a review has occurred, ask for its conclusion in writing.
Ask what happens if you choose not to proceed with proton therapy. For some situations, active surveillance or a different sequence of treatment may be reasonable. The treating team should be able to explain the consequences of each option without pressuring you toward one. If you feel pushed, that is itself useful information about the consultation.
You can also ask how the recommendation might change if a key fact changed. For example, if the pathology were revised, or if further imaging showed a different extent of disease, would the plan stay the same? This question tests whether the recommendation rests on solid ground or on assumptions that still need checking.
If you seek a second opinion, ask the first team to share the imaging and the proposed plan rather than a summary alone. A second clinician can only compare alternatives if they can see the same target and the same dose constraints. Keep copies of everything you send, and note the date of each version, so that later discussions refer to the same records.
Centre Acceptance and Eligibility Are Separate Questions
Being a possible candidate for proton therapy is not the same as being accepted by a specific centre. Each facility has its own criteria, capacity, and planning process. The hospital decides suitability. No enquiry service can promise acceptance.
Ask the centre directly: "Based on these records, would you accept this patient for assessment, and what further information would you need?" Ask whether the acceptance decision is made by a radiation oncologist, a multidisciplinary board, or another committee. Ask how long that decision typically takes for cases like yours, and whether the answer is provisional or final.
If you are working with a coordination service, its role is non-clinical. It can help organise records, appointments, and communication. It does not decide eligibility, prescribe treatment, or guarantee that a hospital will accept you. Keep that boundary clear in your own mind.
Ask what the centre's written estimate includes and excludes. Do not assume that a quoted figure covers planning scans, immobilisation devices, daily sessions, imaging during treatment, or follow-up. Ask for the scope in writing before you commit to travel.
Planning Visits, Sessions and Follow-Up
Proton therapy is not a single appointment. It involves assessment, planning imaging, a treatment plan, a series of sessions, and follow-up. The number of sessions depends on the diagnosis and the plan, so ask the team to explain the proposed schedule for your case rather than relying on general figures.
Ask how many planning visits are needed before treatment starts, and whether any of them can be done remotely. Ask how many treatment sessions are planned, how long each visit takes, and whether you need to stay near the centre for the whole period. These are practical questions that affect travel, accommodation, and work.
Ask what follow-up looks like after treatment. Who will review you, how often, and what imaging or tests will be used? If you plan to return home, ask how the centre will communicate with your local clinicians and what records you will receive.
Do not treat any of these answers as fixed until the centre confirms them in writing. Schedules can change if planning reveals new information or if the clinical picture changes.
What to Prepare and What to Ask Next
Before you contact a centre or a coordination service, gather the records that make a clinical review possible. These typically include imaging reports and the images themselves, pathology reports, operative notes, and a summary of treatments already received. A short list of your current medications and allergies is also useful.
You do not need to send a complete medical archive at the first contact. A brief summary of the diagnosis and your main question is enough to start. The team can then tell you what else is needed.
When you speak with a clinician, ask for the assessment in writing where possible. A written summary of the proposed target, the alternatives considered, the main risks, and the planned schedule is easier to review with your family or local doctor.
If you want help organising a records-based review or an appointment with a relevant specialist in China, you can begin with a free initial enquiry. That step does not commit you to treatment, and it does not replace the hospital's own eligibility decision. The next practical action is to ask the treating team the questions above and request their written response before making travel plans.
