In plain language
Spread throughout, without a single edge to point at. It says a change involves a whole organ or region rather than sitting in one place — which often points to a process affecting the whole body rather than a lump.
Where you’ll see this
Throughout the findings, on every modality.
Your report may word it “Diffusely” or “Generalised”. These mean the same thing.
Questions worth asking your doctor
- In plain terms, how big or how serious is what you are describing?
- Does this description point to one likely cause, or several?
- Does anything here explain the symptoms I came in with?
