bladder cancer
Let an agent explain bladder cancer and its types in general terms from urology and oncology guidelines, describe risk factors, symptoms, diagnosis and treatment approaches, 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 bladder cancer and its types in general terms from urology and oncology guidelines, describe risk factors, symptoms, diagnosis and treatment approaches, and route personal questions to clinicians.
Cancer arising in the urinary bladder, chiefly urothelial carcinoma in papillary and flat forms including flat intraepithelial lesions, ranging from non-muscle-invasive tumours managed by resection and intravesical therapy to muscle-invasive disease requiring cystectomy or chemoradiation, with rarer types such as urachal carcinoma, squamous and small cell carcinomas and inflammatory myofibroblastic tumours, and sites such as the lateral wall and bladder neck; smoking and occupational chemicals are major risk factors, and blood in the urine is the main warning sign.
What it is for: Not applicable; a cancer.
It can be explain types and risk factors; relay symptoms and diagnosis; relay treatment approaches; route personal questions.
Distinguishing features
Urothelial origin
Smoking as main risk
High recurrence
Stage-dependent treatment
What it looks like
Not a visible object; tumours seen at cystoscopy.
Physical character
new cases worldwide: about 610000 per year - GLOBOCAN 2022
non-muscle-invasive share: about 75 percent - at diagnosis
How it is recognised
Malignant tumour of the bladder
Urothelial carcinoma, papillary and flat lesions, rare types, sites
Benign bladder tumours and papillomas are not cancer; kidney and prostate cancers are separate
