Precision medicine is an emerging field. Advances in next-generation sequencing and related sequencing technologies have enabled the integration of bioinformatics and big data for personalized medicine optimization. Thus, precision medicine has become the focus of medical development worldwide. The first step in this approach involves employing next-generation gene sequencing and simultaneously collecting patients’ clinical and genomic information, contributing to the construction of a comprehensive database. This would facilitate the acquisition of knowledge on suitable treatments, thereby benefiting patients and accelerating the development of medical techniques and new drugs to become a driving force for advances in related industries.
