This page is about logistics. Whether treatment in Korea is right for you, and which treatment, are questions for oncologists who have seen your records — yours at home and the one you consult in Korea.

#From first email to first treatment day

The shape is the same at every large hospital: a remote review of your records through the international centre; an arrival week in which the hospital repeats or re-reads imaging and pathology, because it plans treatment on its own findings; a treatment plan from the specialist, often after a multidisciplinary meeting, with a revised estimate; the treatment itself, as an inpatient for surgery or in outpatient cycles for chemotherapy and radiotherapy; and a handover of records and a treatment summary in English for the team that follows you at home. In weeks:

1. Week 0First contact with the international centre through the hospital's official site. You send a short case summary and ask how they want records delivered.
2. Weeks 0–2Records go in: pathology reports, imaging files, treatment history, medication list. Expect at least one round of 'please also send'. Some hospitals charge a consultation or review fee at this point.
3. Weeks 1–3The department replies: whether it can help, which specialist, which tests on arrival, and a cost estimate given as a range.
4. Weeks 2–5Deposit, appointment confirmation and, if your nationality needs one, the visa application using the hospital's appointment letter. Book flights only after the dates are confirmed.
5. Arrival weekRegistration, first consultation, repeat or additional imaging and blood tests, pathology re-read. Treatment rarely starts in this week.
6. Week 2 in KoreaTreatment plan and revised estimate. Admission for surgery, or the first chemotherapy cycle or radiotherapy planning session.
7. Before you leaveFinal review, documents desk for records and imaging, a written plan for follow-up at home and the surgeon's or oncologist's view on when you can fly.

Those week numbers are planning shapes, not promises. The slow parts are usually on the sending side: getting pathology slides released by the original laboratory, having records translated, and waiting for a visa. Start all three at once rather than one after another.

#How long that takes

For a flight search before anyone has given you dates, a month is the default the calculator on this page uses for a single block of surgery or radiotherapy. It is built from the steps above: an arrival week of work-up, a second week for the plan and admission or the first session, and then either the inpatient stay with its first outpatient check or the daily weekday sessions that radiotherapy runs over several weeks. Treat it as a floor. A course of chemotherapy runs to months whichever country it is given in.

#Records to prepare

Hospitals publish slightly different lists, but they overlap heavily. One public cancer centre's published referral procedure (linked in the sources) asks international patients for a medical letter stating the diagnosis, written pathology reports and biopsy slides, image files of MRI, CT or ultrasound with their written reports, and medication names and doses, all in English, sent as soft copies before any appointment or estimate is made. A practical checklist:

• Pathology: every report, plus the slides or tissue blocks themselves if the laboratory will release them. Ask your laboratory early; release can take weeks and may need a signed request
• Imaging: the actual image files in DICOM format on disc or as a download, together with the radiologist's written reports. Screenshots and phone photos of films are not usable for planning
• Operation notes and discharge summaries for anything already done
• Chemotherapy and radiotherapy history: drug names, doses, dates, number of cycles, radiotherapy dose and field
• Recent blood results, including tumour markers if they were measured
• Current medication list with doses, allergies, and other conditions such as diabetes or heart disease
• Translations into English of the documents above if they are in another language; ask whether a certified translation is needed
• Passport copy, and the name and contact details of your treating doctor at home

#Deposits and billing

• International patients are billed privately, outside national health insurance, at the hospital's international rate
• Expect a deposit before admission or before a treatment block, topped up as it is used; ask for an interim statement every few days as an inpatient
• If an insurer or government sponsor is paying, the hospital needs a guarantee of payment letter before treatment starts; begin that paperwork at the remote-review stage
• Drugs not yet licensed in Korea, or used off-label, may be unavailable or need separate approval. Ask early if your plan at home involved one

What an estimate usually covers, and what it leaves out

Verify before you rely on this: Deposit size, accepted payment methods, international rates and visa categories all differ by hospital and nationality, and change over time. Medical Korea describes two medical visa types: C-3-3 for treatment lasting 90 days or less and G-1-10 for treatment of 91 days or longer, valid for up to one year; both can extend to a spouse or immediate family member who comes to provide care, and both need a document from the Korean hospital confirming the appointment plus proof that you can pay. Confirm the current rules with HiKorea or a Korean embassy, and get every cost estimate in writing.

Verify before you rely on this: As of 26 September 2026, the Ministry of Health and Welfare states that since 25 September 2023 operations under general anaesthesia or sedation must be filmed on operating-room CCTV if the patient or a guardian asks; cancer surgery is done under general anaesthesia, so the rule applies, and the request goes in writing before the day of surgery. The retention and release rules are set out in the red-flag clinic article linked below.

#Ten questions for the international office, in the order they matter

• Which department and which specialist will review my records, and is there a fee for that review?
• Which of my tests will be repeated on arrival, and which results from home will be accepted as they are?
• Will my case go to a multidisciplinary meeting, and how many days after arrival does that usually happen?
• What does the estimate assume (how many ward nights, how many cycles or sessions), and what would push it higher?
• How large is the deposit, when is it due, and how is an unused balance returned?
• Will I be on an integrated nursing ward, or do I need a family member or paid caregiver at the bedside?
• Who do I call at night or at the weekend, and does that person speak my language?
• Can later chemotherapy cycles be given at home to the same protocol, and will the specialist write to my oncologist to set that up?
• Which documents will I be given at discharge, in which language, and how long does the documents desk need?
• Which documents do you issue for a visa application, for me and for the person travelling with me?

#When the remote review says do not travel

A remote review can end with advice not to travel, and that answer is worth having before you buy tickets. Common reasons, in general terms:

• The patient is too unwell for a long flight. Cancer Research UK lists very low platelet counts, significant anaemia, breathlessness on mild exertion and an active infection among the reasons doctors advise against flying
• Recent surgery. The same source notes that after chest, bowel or brain surgery, air trapped in the body usually needs around 7 to 10 days to be reabsorbed before flying, and that people who have had a stem cell or bone marrow transplant are generally advised against travel abroad for at least six months
• The hospital would offer the same standard treatment you can already get at home, so travelling adds cost and risk without adding an option
• The treatment you are asking about is not licensed or not offered for your type and stage of disease
• Funding for the whole course is not in place. Hospitals are reluctant to start a course that may stop half-way

#Living near the hospital

• Korean wards traditionally expect a family member or paid caregiver at the bedside for non-medical help. Integrated nursing care wards, introduced from 2016, have nursing staff provide that care instead, so nobody has to stay with you; ask which kind you will be on
• For outpatient cycles, look for serviced residences or monthly studio rentals near the hospital; nightly hotel rates add up quickly over six weeks
• During chemotherapy your infection risk rises. Choose housing where you can cook and avoid crowded transport, and know the route to the hospital's emergency room
• Ask the international centre for its out-of-hours contact number and what to do if you develop a fever at night

Fever during chemotherapy is treated as an emergency. The US CDC's advice to patients is to call the doctor straight away for a temperature of 38°C (100.4°F) or higher and not to wait until morning. Buy a thermometer on your first day, ask your team when your blood counts are expected to be lowest, and keep the hospital's emergency number and address in Korean on your phone for a taxi driver.

Practical note: Before you leave Korea, collect everything in one go: operation record, pathology reports, imaging on disc, chemotherapy regimen with doses and dates, radiotherapy summary, and a discharge letter in English. Korean hospitals issue these at the documents desk for a fee per copy, with your passport; the Korean names to ask for are listed in the second-opinion article. Requesting them from abroad later is slow and sometimes requires a notarised authorisation.

Be wary of any agency or website promising a cure, a success rate for your case, or a fixed package price for cancer treatment before a specialist has reviewed your records. Hospitals do not sell cancer treatment that way.

#Common questions

What is an integrated nursing care ward, and why does it matter for a foreign patient?

Korean wards have traditionally relied on a family member or a paid caregiver at the bedside for non-medical help. On an integrated nursing care ward, introduced from 2016, nursing staff provide that help, so a patient travelling alone is not expected to hire a caregiver. Whether you will be on one depends on the hospital and the department, and it changes the housing you book and the visa paperwork for a companion, so ask at the estimate stage.

How much deposit does a Korean hospital ask for?

There is no standard figure. The deposit is normally tied to the written estimate for the next block of care (an admission, an operation, a set of cycles) and is topped up as it is used. Ask for the amount, the due date and the refund process in writing before you transfer anything, and pay only to the hospital's own account.

Can a family member come with me, and can they stay in the hospital?

Medical Korea states that both medical visa types can cover a spouse or immediate family member who accompanies the patient to provide care; they need documents proving the relationship. Whether someone can or must stay overnight on the ward depends on the ward type, so ask before you book housing for two.

Can I start treatment in Korea and continue it at home?

Often, for chemotherapy, if your oncologist at home agrees to follow the same protocol and the drugs are available there. Raise it at the planning stage, not at discharge. The Korean team needs to write the regimen, doses and dates in English, and your home team needs to accept the handover before you fly.

What can I do if something goes wrong during treatment in Korea?

Raise it with the international office first and ask for your records. If that does not settle it, the Korea Medical Dispute Mediation and Arbitration Agency (K-medi) takes applications from foreign patients, including those who have gone home, by email or fax. Korea's Easy Law guide says a mediation decision is due within 90 days of the procedure starting, extendable once by 30 days.

Work out the whole trip: open the total cost calculator with 30 nights filled in. That is a planning default, not a schedule — replace it with the dates your own clinic gives you.

Planning the trip? Tick off the trip checklist — what to get in writing, what to pack and which documents to collect before you fly home — and keep the Korean phrase cards on your phone for taxis and pharmacies.
