In plain language
Having a clean, clearly drawn edge. A sharp border tends to be a reassuring feature: things that grow into surrounding tissue usually do not keep tidy outlines.
Where you’ll see this
The findings, describing a nodule, cyst or mass.
Your report may word it “Circumscribed”, “Well-defined” or “Well-marginated”. 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?
