Cheek swabs to detect mutated genes 'could become useful cancer...

Researchers have developed a technique using cheek swabs to detect gene mutations in healthy tissue, potentially revolutionizing cancer prevention strategies by identifying risks associated with ageing and lifestyle choices.

• The new technique analyzes gene mutations in healthy tissue, which can be triggered by factors like ageing, smoking, and heavy drinking, as reported by researchers in a recent study.
• Findings from this study suggest that mapping these mutations could lead to early interventions in cancer prevention, offering a promising avenue for reducing neoplasm risks in at-risk populations.
• This research, published in the journal Nature, emphasizes the potential of DNA sequencing to enhance understanding of cancer development and improve personalized medicine approaches.
