Personalized medicine, also called precision medicine, or theranostics is a medical model that aims to offer the most personalized treatment for the person depending on its characteristics. Therefore, the main idea is to separate people into different groups with medical decisions, practices, interventions, and/or products being tailored to the individual patient based on their predicted response or risk of disease.
Among other things, it also takes into consideration the biology of the patient, and thus even at a genetic level. It goes also by the terms precision medicine, stratified medicine, and P4 medicine, even if they can be differentiated based on nuances.
This is by far my favorite field in biomedicine. For now, I have only had a hint of what it might be to work in this, but I find it very interesting. Particularly, the genetic part of it amazes me. I am looking forward to discovering more about it because it seems great and the possibilities for both patients and medical scientists are huge.
