Some knowledge actually ISN'T always better than none. Imagine you get a scan and find an aneurysm. The aneurysm has a 1/100 chance of rupturing during your life. Surgery is too risky for the relatively small chance of rupture, so the advice is to "watch and wait". Now you have to go to bed every night wondering if tonight is the night that it ruptures and you don't wake up tomorrow. We know that psychological distress exacts a physical toll on the body. So, on net, assuming no rupture, you gained nothing except the harms associated with knowing about the aneurysm, or the harms associated with unnecessary treatment for a low risk condition. This is the case with all kinds of diseases across the board.
