Does it make a difference where you have your chemo or radiology?

I am collating info on this needed urgently. I ask this question because someone I know that has just had nearly 9 months of chemo and radiology for breast cancer (successfully thank goodness) insisted that she had his in central London (I think somewhere near Harley Street or may be the London Clinic - not quite sure) rather then having this in a local private hospital as she did just did not trust the treatemnet to be as good there.

Do you think there is something in this or is it just rubbish? Is one chemo session the same as another? Is "how" it is done important? And if there is some truth in this and you could go anywhere to be treated where would you go? Thanks very much
