The ASCCP Risk-Based Management Consensus Guidelines provide evidence-based recommendations for managing abnormal cervical cancer screening results and cancer precursors, including post-colposcopy and post-treatment scenarios. ASCCP is pleased to offer this app to streamline navigation of the ASCCP Risk-Based Management Consensus Guidelines for abnormal cervical cancer screening tests and cancer precursors. The guidelines articles, as published in the Journal of Lower Genital Tract Disease, as well as the comprehensive risk estimates, can be accessed through https://www.asccp.org/guidelines. These evidence-based management guidelines, initially developed in 2019, came together through a consensus process of 19 organizations. The updated management guidelines aim to: • Allow for a more complete and precise estimation of risk • Provide more appropriate intervention for high-risk individuals (detect and treat more precancer) • Recommend less intervention for low-risk individuals (decrease testing and treatment that won’t prevent cancer and may cause reproductive harm) • Allow for the future addition of new risk modifiers and screening and management technologies See https://www.asccp.org/UserGuide for tips on using the app.

ReceptionRating · Positive reviews · Number of ratings

ASCCP Management Guidelines holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: ASCCP Management Guidelines has 8.6K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 78% of Opioids Dosage Conversion's written reviews are positive against 33% of ASCCP Management Guidelines's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Opioids Dosage Conversion ships an update every 4 months, ASCCP Management Guidelines every 3 months. The most recent releases landed on September 17, 2026 and September 22, 2026 respectively.
