Leukemia care: centres
United Kingdom
Well-known centres
The Royal Marsden, London and Sutton
Great Ormond Street Hospital, London (children)
Good to know: The Royal Marsden has one of the largest transplant units in the UK and treats NHS and private patients. Great Ormond Street has the country’s largest paediatric transplant unit (JACIE-accredited), treats children up to 16 and accepts international referrals through its private care service.
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.
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.
