After it's diagnosed, there's nothing we can really do about it that prolongs life. So two of the most common causes of death we can't do much about once they develop. It's not a good idea to wait for a disease to occur. So we're looking at prevention, we are interested in prevention. Physicians are interested in prevention too, now that they've realized that their typical medical approach doesn't work too well.
People are still sick unnecessarily.
There's a lot of hullabaloo about doing prevention in practice now. Family physicians are probably getting the recognition that they deserve, especially in America. Because in medical school they learn that there are three kinds of prevention. There's primary prevention, where you actually prevent the disease from occurring in the first place, which is what we are really interested in. The second prevention, which is really not prevention at all but early detection, is waiting for a disease to occur before you do anything about it, like breast cancer, or lung cancer, or cancer of the cervix, cancer of the prostate.
