osteosarcoma
Let an agent explain osteosarcoma in general terms from oncology guidelines, describe symptoms, diagnosis, treatment and outcomes, distinguish it from other bone sarcomas and benign bone conditions, 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 osteosarcoma in general terms from oncology guidelines, describe symptoms, diagnosis, treatment and outcomes, distinguish it from other bone sarcomas and benign bone conditions, and route personal questions to clinicians.
The most common primary malignant bone tumour, arising from bone-forming cells, most often in the long bones around the knee and shoulder in adolescents and young adults as pediatric osteosarcoma and with a second peak in older adults, presenting as localized or metastatic disease, and grouped with rarer bone sarcomas such as fibrosarcoma of bone, malignant fibrous histiocytoma of bone and vascular sarcomas; osteosarcoma is treated with chemotherapy and surgery, and survival for localized disease has improved to about 60 to 70 percent.
What it is for: Not applicable; a cancer.
It can be explain the disease; relay symptoms and diagnosis; relay treatment and outcomes; route personal questions.
Distinguishing features
Bone-forming tumour
Adolescent peak
Chemotherapy and surgery
Metastasis to lungs
What it looks like
Not a visible object; a bone tumour seen on imaging.
Physical character
incidence: about 3-4 per million per year
five-year survival, localized: about 60-70 percent
peak age: 10-20 years
How it is recognised
Malignant bone-forming tumour
Localized and metastatic osteosarcoma; pediatric and adult forms; related bone sarcomas
Ewing sarcoma and chondrosarcoma are other bone sarcomas; bone metastases from other cancers differ
