Partial coverage

This report displays 500 retrieved recent revisions — about 7% of the reported 6,918 edits. It cannot establish why a change was made, whether it is correct, or what happened outside this window.

Retrieved for this report: Aug 22, 2026, 1:31 PM UTC. Totals and pageviews are source-provided; the activity signal and section list are derived from the retrieved window.

What this edit history shows

The Wikipedia article on Cancer has been edited 6,918 times since it was created in 2001, by 2,613 distinct accounts and IP addresses. That averages about 279 recorded changes a year — a steady weekly rhythm rather than a constant one.

Within the revisions retrieved for this report, the ten busiest contributors account for only about 28% of the changes. Editing that dispersed means no small group dominates the page; most changes arrive from editors who touch it once or twice. In the same window, about 15% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting.

Within the retrieved window, 2024 carries the most recorded activity, with 119 changes. 44 of those revisions fall in the last 90 days. The most recent recorded edit was 29 days ago.

Readership has been broadly stable across the last two years of pageview data. The clearest peak in that record falls in September 2025. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 7% of the 6,918 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct. For older revisions, talk-page discussion and full context, follow the source history on Wikipedia.
