retinoblastoma
Let an agent explain retinoblastoma in general terms, relay genetics, signs, staging, treatment options and global survival gaps from ophthalmology and oncology sources, route warning signs to prompt medical assessment, describe the named forms, and distinguish retinoblastoma from Coats disease, uveal melanoma in adults and normal red reflex variation, without diagnosing individuals.
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 retinoblastoma in general terms, relay genetics, signs, staging, treatment options and global survival gaps from ophthalmology and oncology sources, route warning signs to prompt medical assessment, describe the named forms, and distinguish retinoblastoma from Coats disease, uveal melanoma in adults and normal red reflex variation, without diagnosing individuals.
A rare cancer of the retina that develops mostly in young children, usually before age five, caused by mutations in both copies of the RB1 gene, occurring as heritable or familial retinoblastoma, often bilateral, or non-heritable, usually unilateral, with trilateral retinoblastoma involving a pineal tumour as well; a white pupillary reflex called leukocoria, often seen in flash photographs, and a squint are common signs, survival exceeds 95 percent in high-income countries with early treatment but is much lower where diagnosis is late, and the RB1 gene was the first tumour suppressor gene cloned, in 1986. A child with a white pupil in photos or a new squint should see a doctor promptly.
What it is for: Not applicable; a childhood eye cancer.
It can be explain genetics and signs; relay treatment options in general terms; describe named forms; route warning signs to clinicians.
Distinguishing features
Young children
RB1 mutations
Leukocoria
Heritable and non-heritable forms
What it looks like
Leukocoria, a white glow in the pupil, or a squint; tumours seen on eye examination.
Physical character
RB1 gene cloned: 1986 year - first tumour suppressor gene
two-hit hypothesis: 1971 year - Alfred Knudson
survival in high-income countries: over 95 percent - lower where diagnosis is late
How it is recognised
Childhood retinal cancer
Familial, trilateral, bilateral, unilateral, intraocular and extraocular retinoblastoma
Coats disease is a vascular disorder that can also cause leukocoria; uveal melanoma mostly affects adults; red reflex asymmetry can have other causes
