Can you expect a young child to wear a t-shirt or shirt the same size as their grandparents? Absolutely you cannot expect. But when individuals are sick, they receive the same medical treatment, although they have many differences. The main reason for this is that even the world’s best scientists and doctors do not fully understand how diseases develop in humans and how they respond to treatments. Therefore, a one-size-fits-all drug approach is applied based on large population averages. Traditional practice does not usually have the same effect on everyone, as the genetic structure of each person is slightly different. Even small differences in people’s genetic makeup can have important health consequences.
Personalized medicine helps achieve the goal of more precise, predictable, and robust healthcare for each patient. Advancing our knowledge of genetics and genomics on important issues such as how each person responds to drugs and diseases enables physicians to better prevent disease, diagnose better, prescribe safer drugs, and administer more effective treatment. The basis of Personalized medicine is the provision of health services in accordance with the unique genetic makeup of the person. Personalized medicine is also known as individualized medicine, precision medicine, or genomic medicine.
