Cervical cancer can be prevented with detection and treatment of precancerous cell changes caused primarily by high-risk types of human papillomavirus (hrHPV), the causative agents in more than 90% of cervical cancers. ⋯ Primary hrHPV screening detected higher rates of CIN 3+ at first-round screening compared with cytology. Cotesting trials did not show initial increased CIN 3+ detection. Both hrHPV screening strategies had higher false-positive and colposcopy rates than cytology, which could lead to more treatments with potential harms.
