Study: More cancer testing = more false alarms

May 12, 2009 That may seem like common sense, but it's not something that patients or doctors often consider. That's the finding of a study in the Annals of Family Medicine.

False positive results from routine cancer screenings can cause undue worry and in some cases lead to unnecessary biopsies or treatments.
