basal-cell carcinoma of the skin
Let an agent explain basal cell carcinoma in general terms, relay prevention, warning signs and treatment information from dermatology bodies, distinguish it from other skin cancers, and route personal skin changes and treatment 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 basal cell carcinoma in general terms, relay prevention, warning signs and treatment information from dermatology bodies, distinguish it from other skin cancers, and route personal skin changes and treatment questions to clinicians.
The most common form of skin cancer, arising from basal cells of the epidermis on sun-exposed skin, especially the face, in fair-skinned and older people; it grows slowly, rarely spreads, but can invade and destroy local tissue if untreated, and is cured in most cases by surgical removal or other local treatments.
What it is for: Not applicable; a cancer.
It can be explain the cancer and its course; relay prevention and warning signs; relay treatment options in general terms; route personal questions to clinicians.
Distinguishing features
Arises from basal cells
Ultraviolet exposure as main cause
Local invasion, very rare spread
High cure rate
What it looks like
A pearly or waxy bump, a flat scar-like patch, or a sore that bleeds and does not heal, usually on the face or other sun-exposed skin.
Physical character
share of skin cancers: about 70-80 percent - of non-melanoma skin cancers
metastasis: under 0.1 percent - very rare
How it is recognised
Slow-growing skin lesion on sun-exposed skin
Pearly, translucent or ulcerated forms
Melanoma and squamous cell carcinoma are other skin cancers with different behaviour
