The NHS regularly removes warts just like anyone else, I can assure you. I find this odd, I can only assume that he went once or twice to a GP, it didnt clear, and he didnt go back to see a doctor.
I know from family experience that if creams etc fail, then a British GP will refer the patient to hospital for a minor op (ie removal). In fact, I am not sure that some larger surgeries wont do it there by a senior nurse.
We should just all quit playing with toads and frogs. Problem solved.
