Ideally, but it’s hard to test this, as you either need to know who is going to get a disease, or treat thousands of people, only a few of which would get sick anyway. What we try to do is two Hingis. First, find cures that you can give to people diagnosed early in disease, that slow or stop it getting worse. Second were looking in some cases at whether we can find a chemical in blood that predicts IF you are likely to get a disease in the future.
