Abstract Purpose: The internet has become a central resource for cancer patients, with recent studies reporting 60% to 75% of cancer patients using online resources. However, the quality of these resources is variable, and a better understanding is needed to guide physicians in how to best support patients in their online searches. We previously evaluated the quality of online breast cancer resources in 2011. Now, nearly a decade later, we aimed to assess the present quality of online breast cancer patient information and to compare our current analysis to data collected in 2011. . Materials and Methods: A list of top 100 breast cancer websites was systematically compiled using meta-search engines Yippy, Dogpile, and Google using the search term “breast cancer”. Content accuracy and quality markers, including authorship, attribution, currency, site organization, and readability were assessed using a previously validated standardized rating tool. Results were analyzed using descriptive statistics and Fisher’s exact test. The same strategy was used in both 2011 and 2019. . Results: When comparing current data to 2011, authorship identification increased, with 34% of websites identifying an author in 2011 compared to 45% in 2019 (p=0.004). Only 31% of websites analyzed in 2019 used two or more reliable sources, while 62% had no reliable sources or no sources cited. Website disclosure and objectivity remained similar in both data sets. Twenty seven percent of websites were updated in the last 2 years in 2011 compared to 65% in 2019 (p&amp;lt;0.0001). From 2011 to 2019, resources with readability above grade 12 increased from 4% to 30% (p&amp;lt;0.0001), while websites offering educational support rose from 8% to 35% (p&amp;lt;0.0001). In 2019, treatment and etiology/risk factors were the most accurately covered (64% and 63% of websites, respectively). This was similar to 2011 data, which found 63% of websites to be globally accurate. Prognosis coverage increased from 18% to 33% from 2011 to 2019 (p=0.023). In 2019, survivorship was also evaluated, and found to be covered in only 24% of resources. Conclusions: Over the past 8 years, there has been some improvement in the quality of online breast cancer resources. Promisingly, websites are being updated more frequently and the educational support offered is expanding. Furthermore, there has been significant improvement in the coverage of prognosis, although this requires further progress. Unfortunately, websites are becoming increasingly challenging to understand for an average patient, and coverage of survivorship is lacking. Our study informs healthcare providers on these trends in online breast cancer resources and how to best support patients in their internet searches.
