The Rotterdam Prostate Cancer Risk Calculator is based on ERSPC, Rotterdam, data and supported by the Prostate Cancer Research Foundation, Rotterdam (SWOP)     The Prostate Cancer Research Foundation, Rotterdam, Stichting Wetenschappelijk Onderzoek Prostaatkanker (SWOP), is an initiative of the Department of Urology of the Erasmus MC, the University and Medical Centre of Rotterdam, in The Netherlands. Its goal is the financial support of scientific research projects in the field of prostate cancer, as well as other cancers of the urinary tract. Please be aware that the Rotterdam Prostate Cancer Risk Calculator for iOS cannot be 100% accurate at predicting the presence or absence of prostate cancer. It is designed to help calculate your risk, not give a definitive diagnosis. The Rotterdam Prostate Cancer Risk Calculator for iOS provides a general risk calculation based on your PSA level and other information. While knowing your PSA level is helpful, the decision to have a PSA test has to be taken seriously after weighing up all factors and discussing the implications with your GP or hospital doctor. It is possible that prostate cancer will not be found even if you have an elevated PSA. However, it may be present even if your PSA level is low. Your doctor may want to take further tests. If you have doubts or questions about your health, you should always contact your GP or hospital doctor. This is particularly important if you have questions which arise from the use of our prostate cancer risk calculator. It cannot be ruled out that the way the Rotterdam Prostate Cancer Risk Calculator for iOS is used, or the indications given by it, are interpreted in a manner that is not appropriate. The creators of the Rotterdam Prostate Cancer Risk Calculator for iOS do not accept any responsibility in any respect. The European Randomized Study of Screening for Prostate Cancer has published its 11-year follow-up results (New England Journal of Medicine, March 15 2012). Once again, they demonstrate that screening does significantly reduce death from prostate cancer. The latest study confirms that a man who undergoes PSA testing will have his risk of dying from prostate cancer reduced by 29%. ERSPC is the world’s largest randomized prostate cancer screening study. It was designed to investigate whether early detection and treatment of prostate cancer might reduce disease-specific mortality and also help to identify men at risk. From 1992, the ERSPC study randomized 162,000 men, aged 55 to 69, across Europe to either a screening arm or a control group. Designed and developed for iOS by Nuno Azevedo of Ydeal.net Software LDA

The National Comprehensive Cancer Network® (NCCN®), is pleased to present the Virtual Library of NCCN Guidelines® app formatted for iPhone & iPad. This easy-to-use and convenient format will further assist health care professionals in their implementation of the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®), thus improving the quality and effectiveness of care provided to patients with cancer. NCCN is a not-for-profit alliance of leading cancer centers devoted to patient care, research, and education. NCCN is dedicated to improving and facilitating quality, effective, efficient, and accessible cancer care so patients can live better lives. Through the leadership and expertise of clinical professionals at NCCN Member Institutions, NCCN develops resources that present valuable information to the numerous stakeholders in the health care delivery system. By defining and advancing high-quality cancer care, NCCN promotes the importance of continuous quality improvement and recognizes the significance of creating clinical practice guidelines appropriate for use by patients, clinicians, and other health care decision-makers around the world. Over the past 25 years, NCCN has developed an integrated suite of tools to improve the quality of cancer care. The NCCN Guidelines® document evidence-based, consensus-driven management to ensure that all patients receive preventive, diagnostic, treatment, and supportive services that are most likely to lead to optimal outcomes. The NCCN Guidelines are a comprehensive set of guidelines detailing the sequential management decisions and interventions that apply to 97 percent of cancer cases in the United States. In addition, separate guidelines relate to major prevention and screening topics and another set of pathways focuses on the major supportive care areas. The NCCN Guidelines provide recommendations based on the best evidence available at the time they are derived. Because new data are published continuously, it is essential that the NCCN Guidelines also be continuously updated and revised to reflect new data and new clinical information. The intent of the NCCN Guidelines is to assist in the decision-making process of individuals involved in cancer care—including physicians, nurses, pharmacists, payers, patients and their families—with the ultimate goal of improving patient care and outcomes. The NCCN Guidelines provide recommendations for appropriate care for most but not all patients; however, individual patient circumstances must be considered when applying these recommendations.

Verdict

The call

The clearest difference is price: NCCN Guidelines® at Free against Cancer Risk's $1.99. NCCN Guidelines® also leads on rating (3.6 vs 2.0) and ratings volume (24 vs 1). Cancer Risk's advantage is review sentiment (33% vs 13%). On update cadence, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

NCCN Guidelines® holds the better App Store score, 3.6 against 2.0. That said, the two scores are not equally well evidenced: NCCN Guidelines® has 24 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Cancer Risk's written reviews are positive against 13% of NCCN Guidelines®'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cancer Risk ships an update every 3 months, NCCN Guidelines® every 2 months. The most recent releases landed on November 11, 2026 and November 1, 2026 respectively.
