Biopsy Biopsy
Takes a small tissue sample to examine under a microscope. Several routes exist: fine needle, core needle, partial or complete excision.
What it can show
The cellular nature of a lesion. This is the step that gives certainty instead of inference from imaging.
What it cannot show
Represents only the exact spot sampled. A miss means a negative result still does not exclude — which is why a repeat biopsy is sometimes needed.
This is the half people skip. A normal result answers one question, not every question.
Tell the staff before you start
All blood thinners, aspirin and supplements · bleeding disorders · anaesthetic allergy · current antibiotics.
Also bring the full list of every medicine and supplement you take. Things bought without a prescription belong on that list too.
