Isn't that pretty stupid? I think I remember a scientist who said that if you make an examination like this you will ALWAYS find something. And most of the time "fixing" it is worse then letting it be. Because of that screening can be bad and good and it is normally only done for specific affliction where it has been shown to lower the overall risk of a serious disease.

For example it has been shown in studies that screening for breast cancer esp. for women with familiar risks is lowering death rates but I think this isn't even that clear anymore for colonic cancer and for other afflictions the risks that are included in the screening process itself, the diagnosis (for example biopsy) and the therapy for something that has not yet had any effect on the live of the person is worse than the risk of the affliction itself.
