Knowing today how you can stay tomorrow is possible. Predictive medicine is able to give us answers. And no, it is not about predating the future as a sorcerer would do, but of identifying the real possibility in a human subject to develop pathologies starting from genetic and molecular data. In practice, in a healthy individual, the predisposition to develop diseases is as early as possible.
The idea will be afraid, but up to a certain point. Because on the one hand there is the preventive medicine that is making enormous steps forward (and in the case of a genetic predisposition can allow you to make even very early diagnoses), on the other there is theepigeneticsthat is, the study of how genes are adjusted without changing the DNA, which It allows us to intervene and improve (or worsen) a genetic structure that has possible risk factors.
Adopting a healthy lifestyle is what can allow us to change and improve our genes. This possibility is also called “proactive” medicine, because it indicates how the human individual, through certain behaviors, can greatly reduce his negative genetic predispositions and enhance positive ones. Nutrition, in this sense, has a fundamental influence. Sports activity has the same, as well as sleep. Even living in a positive environment and keeping optimistic are fundamental elements in this sense.
A typical example of predictivity are the genetic screening performed to investigate the predisposition to have tumors, now very popular especially in the case of possible familiarity. Do Angelina Jolie and Bianca Balti tell you anything?
Of course, thinking of undergoing a genetic test is not easy. It is one thing to do it limiting itself to the factors that accelerate aging, one account is if the research is aimed at genes potentially connected to specific diseases. The psychological impact is not secondary and also for this reason the specialized centers always suggest a comparison first with their doctor, in addition to that with a psychologist.
Discovering what is written in one’s genes can upset life (he did it in part with Chris Hemsworth, when he discovered he has a genetic predisposition to Alzheimer’s) but it is not a “condemnation”, but an opportunity to change what could be an inauspicious destiny. Perhaps, in this perspective, it can be worth it.
