Precision medicine is a relatively new and emerging field in healthcare. It focuses on disease treatment and prevention by taking into account an individual’s genetic variations, the effect of environment and a person’s lifestyle preferences. This approach is more accurate in treating diseases as it is based on a person’s genetic framework. Precision medicine is quite the opposite of the generalized “one-size-fits-all” idea of treating diseases in terms of effectiveness. Here, disease treatment and prevention strategies are focused to meet an individual’s needs and specifications.
