People assume a second read is a formality. A quick nod that agrees with the first.
That is not what it is.
A second opinion changes the plan when it surfaces something that reshapes care. A finding that moves a patient toward the right specialist. A detail that answers the exact question the referring physician was asking. Context that turns a vague impression into a clear next step.
The value is not in disagreeing for its own sake. The value is in reading the study as if the answer matters, because for the patient it always does.
If a fresh set of trained eyes cannot change anything, the case was already in good hands. When it can, you want to know.
