<strong>Precision Medicine</strong>（精准医疗）是一种新兴的疾病预防和治疗策略，其核心理念是考虑到每个人在<strong>基因 (Genes)</strong>、<strong>环境 (Environment)</strong> 和 <strong>生活方式 (Lifestyle)</strong> 上的个体差异，从而制定个性化的医疗方案。与传统的“一刀切” (One-size-fits-all) 模式不同，精准医疗旨在通过 <strong>[[Genomics]] (基因组学)</strong>、<strong>[[Big Data]] (大数据)</strong> 和 <strong>[[Biomarker]] (生物标志物)</strong> 技术，在正确的时间，将正确的药物给予正确的患者 (Right Drug, Right Person, Right Time)。目前，该领域应用最成熟的方向是<strong>[[Oncology]] (肿瘤学)</strong>，例如针对特定基因突变的靶向治疗，同时正迅速扩展至心血管疾病、罕见病及精神类疾病领域。<br />
