“Screening is not for people who have symptoms. People who have symptoms should always consult their GP.”

Could it find something that isn’t there?
The Royal College of Radiologists, on MRI scans, which this clinic offers
“If you have no symptoms, we don’t recommend trying to get an MRI scan without being referred by a doctor, as there is a chance of overdiagnosis and treatment of irregularities that turn out to be nothing to worry about. This can cause unnecessary anxiety and can even lead to unnecessary treatment.”
