New study shows mouth swab can predict mortality risk using CheekAge method

A new study reveals that a simple mouth swab can estimate a person's risk of dying. Researchers developed a method called CheekAge, which analyzes cells from the cheeks to measure epigenetic changes linked to aging and lifestyle factors. CheekAge is based on data from over 1,500 individuals and can predict mortality risk more effectively than previous methods that relied on blood samples. The study found that specific genetic markers in cheek cells correlate with overall health and aging. The researchers identified genes associated with mortality, including those linked to cancer and heart health. They suggest that CheekAge could be a valuable tool for studying aging and related diseases in a non-invasive way.
