A new DNA tool reveals aging, smoking, and alcohol leave genetic marks, with mutations in healthy tissue hinting at future cancer risk.
A new DNA sequencing tool called targeted NanoSeq has enabled researchers to detect rare mutations in healthy tissues with high accuracy, revealing that aging, smoking, and alcohol use leave distinct genetic signatures.
In a study of over 1,000 people, scientists identified hundreds of thousands of mutations, including tens of thousands in cancer-related genes, with some mutations showing signs of growth advantage.
While most mutant cell clones remain small and stable, the findings suggest these changes could serve as early indicators of cancer risk.
The technique also found that harmful mutations in sperm increase with paternal age, raising concerns about inherited genetic risks.
The method, now widely used in research, may help predict cancer risk and improve prevention strategies.
