Precision medicine is an emerging approach to patient care. Physicians choose a treatment method based on the patient's genetic makeup (including genetic changes resulting from a disease) and lifestyle habits. It is an emerging disease treatment and prevention approach that considers individual variability in genes, environment, and lifestyle. Precision medicine can remove the need for guesswork, variable diagnostic ability, and treatment strategies based on generalized demographics. Moreover, precision medicine enables a more holistic view of an individual patient. Precision medicine for clinical workflow helps facilitate more predictive and preventive care through targeted therapies.
