The data isn&#x27;t &quot;dirty&quot;, it&#x27;s perfectly accurate. You are just using it wrong. The test can give you an objective answer like &quot;you have a 20% probability of having cancer&quot;.<p>But the system doesn&#x27;t weigh the cost and Quality Adjusted Life Years of treatment vs not treatment, it just defaults to treatment. This is the problem that needs to be fixed, not eliminating collecting data.<p>And if the patients really are the problem, then don&#x27;t show them the raw numbers. But having them is potentially useful. But maybe they should see the numbers, and maybe if they decide on treatment anyway that is their right to do so, and taking it away is wrong. Either way the problem is the system, not tests themselves.
