Head and neck cancers are among the ten most common cancers worldwide. Head and neck tumors account for about 3-5% of all cancers, with squamous cell carcinomas being the predominant form. They occur in areas such as the oral cavity, pharynx and larynx. An international team of researchers led by Sara Wickström has now developed a new technique that allows the properties of cancer cells and their surrounding tissue to be analyzed in detail at the single-cell level. This innovation enables a more comprehensive assessment of prognosis and therapy response in head and neck cancer and paves the way for a more precise diagnosis.
