mouth cancer
Let an agent explain mouth cancer and its sites in neutral clinical terms, relay risk factors, symptoms, diagnosis and treatment in general from oncology guidelines, describe prevention and screening, and route people with symptoms to dentists and 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 mouth cancer and its sites in neutral clinical terms, relay risk factors, symptoms, diagnosis and treatment in general from oncology guidelines, describe prevention and screening, and route people with symptoms to dentists and clinicians.
Cancer arising in the oral cavity, including the tongue, floor of the mouth, gums, cheek mucosa, hard palate and retromolar area, most often squamous cell carcinoma linked to tobacco, alcohol, betel quid and human papillomavirus, with precursor stages such as carcinoma in situ, and in the registry sense grouped with salivary gland cancers, which are distinct tumours; mouth cancer presents as persistent ulcers, lumps or patches and is treated by surgery, radiotherapy and chemotherapy, with outcomes depending on early detection.
What it is for: Not applicable; a disease.
It can be explain sites and causes; relay diagnosis and treatment; describe prevention; route to clinicians.
Distinguishing features
Oral cavity site
Tobacco, alcohol and betel links
Visible early signs
Multimodal treatment
What it looks like
Not a visible object as a category; ulcers, lumps or red and white patches in the mouth.
Physical character
global cases: about 380000 per year - lip and oral cavity, estimates
main type: squamous cell carcinoma note - about 90 percent
five-year survival: about 50-65 percent - varies with stage
How it is recognised
Cancer of the oral cavity
Tongue, floor of mouth, gum, cheek mucosa and retromolar cancers, carcinoma in situ; salivary gland cancers as a related group
Oropharyngeal cancer is behind the mouth; lip cancer is sometimes classed separately; benign ulcers heal

- How should oncology guidelines be linked?
- The registry entry has merged aliases naming sites and a distinct cancer group; should they be split off?
