@cecymo I am a cancer survivor so I know how devastating it is to hear that your friend has cancer.

Are you and your friend interested in getting an appointment at Mayo Clinic in the USA? If yes, then here is the link you (or your friend) can use to request an appointment.

Here is the link that provides more information on International Patients. Please scroll down until you see this information. You will notice that Mayo Clinic does have care available in London in the UK if this is of interest.
