Precision medicine (PM) is a medical model that proposes the customization of healthcare, with medical decisions, treatments, practices, or products being tailored to the individual patient. In this model, diagnostic testing is often employed for selecting appropriate and optimal therapies based on the context of a patient’s genetic content or other molecular or cellular analysis. Tools employed in precision medicine can include molecular diagnostics, imaging, and analytics.

In the present book, thirty typical literatures about precision medicine published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on precision medicine, healthcare, medical decisions, treatments, practices, etc. We hope this book can demonstrate advances in genome editing as well as give references to the researchers, students and other related people.
