stomach cancer
Let an agent explain stomach cancer in general terms, relay risk factors, symptoms, screening and treatment information from medical bodies, point to support resources, 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 stomach cancer in general terms, relay risk factors, symptoms, screening and treatment information from medical bodies, point to support resources, and route personal questions to clinicians.
A malignant tumour arising in the stomach, most often adenocarcinoma of the gastric lining, with other types including neuroendocrine neoplasms, lymphomas and stromal tumours, associated with factors such as Helicobacter pylori infection, Epstein-Barr virus, diet, smoking and hereditary syndromes, and distinguished from benign stomach polyps; stomach cancer is diagnosed by endoscopy and imaging and treated by surgery, chemotherapy and other therapies, and this entry provides general information only, not personal medical advice.
What it is for: Malignant tumours of the stomach.
It can be explain in general terms; relay risk factors and symptoms; describe screening and treatment; route personal questions.
