Cheek swabs to detect mutated genes 'could become useful cancer prevention tool'

A new technique using cheek swabs to identify gene mutations in healthy tissue shows promise as a cancer prevention tool, potentially changing early detection methods.

• Researchers analyzed cheek swabs from 1,042 individuals and 371 blood samples, indicating a comprehensive approach to detect genetic mutations linked to cancer.
• The study, published in the journal Nature, highlights how mapping mutations in healthy tissue could identify risks for developing neoplasms like bladder cancer.
• Using DNA sequencing, the technique aims to uncover mutations before they lead to cancer, enhancing preventative measures and early intervention strategies.
