From blunt-force treatment to precision: 25 years of transformation in cancer research
Nature Reviews Cancer, Published online: 22 September 2026; doi:10.1038/s41568-026-00980-6This Editorial marks the 25th anniversary of Nature Reviews Cancer. On this milestone we contemplate how our view of cancer has changed over the past 25 years and speculate on what the future holds.

Paying peer reviewers works. Expanded Fast & Fair experiment @biologyopen.bsky.social: • 5.5 vs 37.7 working days to decision with reviews • ~3 vs ~9 reviewer invitations per manuscript • no reduction in editor-assessed review quality • similar acceptance rates www.biorxiv.org/content/10.6...
Scatter plot showing that Fast & Fair peer review reached first decision with reviews much faster than conventional peer review: mean 5.5 versus 37.7 working days. Most Fast & Fair manuscripts met the 7-working-day target, while conventional manuscripts were slower and more variable, up to 116 working days.
