biopsy
Let an agent explain biopsies and their kinds in general terms from clinical sources, describe what to expect, risks and how results are used, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain biopsies and their kinds in general terms from clinical sources, describe what to expect, risks and how results are used, and route personal questions to clinicians.
A medical procedure that removes a sample of tissue or cells from the body for examination, usually under a microscope, to diagnose disease, especially cancer, inflammation and infection, in forms such as needle, core, excisional and endoscopic biopsies, bone marrow biopsy, muscle biopsy, pleural and transthoracic lung biopsies, gut biopsies and bronchoscopic cryobiopsy; biopsies are invasive tests with small risks and are central to pathology and personalised treatment.
What it is for: Diagnosing disease from tissue samples.
It can be explain kinds and purposes; relay procedure and risks in general terms; describe how results are used; route personal questions.
Distinguishing features
Tissue removal
Histopathological analysis
Diagnostic gold standard for many conditions
Invasive with risks
What it looks like
A procedure with a needle, scalpel or endoscope; a small tissue sample in a container.
How it is recognised
Tissue sampling for examination
Needle, core, excisional, endoscopic, bone marrow, muscle, lung, gut biopsies
Blood tests sample fluid; imaging does not remove tissue; liquid biopsy analyses blood for tumour DNA

- How should clinical guidelines be linked?
- The registry entry has merged aliases naming specific procedures; should they be split off?
