With the development of personalized medicine, individual healthcare became better, however this approach triggered concerns related to data privacy.
It is clear that the individual healthcare plan would certainly assist in order to avoid surprising illnesses. Cancer for example is really hard to notice in the early stages, and it might become inevitable after certain stages. With personalized treatments individuals have a chance to be aware of their illnesses in the early stages.
Furthermore, it might serve as an individual plan for patients. For instance, people who are addicted to drugs, cigarettes and alcohol can get a real plan about quitting it, if they want. Personalized plan for the unique problems, habits, and addictions of people can be a solution.
On the other hand, you really jeopardize your privacy. Doctors will get access to your personal life and information. Moreover, the cost of this procedure might be unaffordable for many people and it makes a contrast between wealthy and poor people. It might be seen as unfair way for many people regardless of their status.
To conclude, although you risk your privacy, you can be aware of lethal diseases, and it will cost a lot of money so many people would not be able to afford it. But if you look at this from another angle, it is just an opportunity for people to be aware of their health, and the world will be the same even without it, so it is an extra chance for people that does not directly affect, and health of people who can not afford it.
