Up to 45% of cervical cancer screening is overuse, which can lead to increased healthcare costs. In a systematic review of published studies conducted by a working group of the Cancer Prevention & Control Research Network (funded by the CDC and NCI), the authors examined which patients were receiving more screening than recommended by guidelines. In their review they identified 25 studies of cervical cancer screening overuse. Researchers found a connection between age, OBGYN provider, location and marital status in the cases of overuse in cervical cancer screening.
