The opposite biggest threat is a false optimistic. That is the place the imaging suggests most cancers, however additional assessments rule it out. This varies throughout research from virtually 1 in 10 to 1 in 2 of these having their first scan. If imaging suggests most cancers, this often requires a repeat scan.
