Cancers exhibit a four-fold higher mutation burden than normal tissues across five organs, driven by individual baseline mutation rate differences.
- Why it matters: Understanding why cancer cells accumulate more mutations is crucial for unraveling tumor development and improving prevention strategies, addressing a key gap in cancer biology.
- What they did: The study systematically compared mutational burdens in normal and cancer cells from five organs, testing three hypotheses to explain the increased mutations, with a focus on baseline mutation rates.
- The result: Findings suggest that individual differences in baseline mutation rates largely account for the elevated mutation burden in cancers, offering new insights for targeted prevention approaches.
