Health system overview
Medical care is usually of a good standard but can be expensive for visitors; staff may not speak English.
Leukemia care: centres
South Korea
Well-known centres
Catholic Hematology Hospital, Seoul St. Mary’s Hospital, Seoul
Asan Medical Center, Seoul
Good to know: Seoul St. Mary’s reports 11,692 transplants between 1983 and 2025, most of them allogeneic; Asan describes itself as the most active centre for haploidentical transplants in Korea. Large hospitals have international healthcare centres.
Wherever you live, the core rules with low immunity are the same: clean hands, keeping raw and cooked food apart, cooking thoroughly, chilling quickly and choosing pasteurised dairy. At local markets and street stalls, watch how food is stored. Ask your team whether tap water is fine for you; if unsure, use bottled or boiled water.
Hospital daily life
In these countries daily care is usually provided by nurses, meals come from the hospital kitchen and visiting hours are set. If you want to bring food from home, ask the ward first. An interpreter can often be booked in advance.
If you are admitted, especially when seriously ill, the hospital may ask you to bring a guardian ("bohoja") to help with daily care; paid caregiver ("ganbyungin") agencies also exist.
Travel during treatment
Talk to your care team before planning a trip — timing, blood counts and vaccines.
Carry a doctor’s letter with your diagnosis, treatment plan and medication list (including in English).
Pack medicines in original packaging, in hand luggage, with extra; some medicines have import rules.
Get travel insurance that covers your existing condition and read the terms.
Find the nearest haematology centre and the emergency number at your destination in advance.
Live vaccines can be unsafe during treatment — ask your team before any vaccination.
Ask your team about clot risk on long flights and move around when you can.
