WHAT IS PRECISION MEDICINE?
The right treatment, for the right person, at the right time.
Precision Medicine is a highly personalized approach to healthcare that uses a person’s unique genetic, environmental and lifestyle factors to customize medical treatments and health surveillance strategies, aiming to delay and prevent the onset of chronic disease.
This is deep learning on the study of you: empowering optimization of present health status with an active forecast of your aging trajectory. When you can identify your rate of biological aging, you can choose to implement targeted interventions and treatments to “age later.”
