Hi Annie
A very good friend of mine is the Matron (yes they still have them in private hospitals in the UK) of a private hospital and this hospital belongs to a group of around 32 all over the UK. I'll contact her with your scenario assuming you are bringing the drug with you to see which ones do chemo. How many hours does it usually take to infuse? I had different chemo so have no idea about Herceptin. I know from working in the private sector they usually charge by the hour. I'll send her an email tomorrow and will let you know once I hear something. I hope this can be done as it would just make your trip more enjoyable without the stress of missing treatment.
