Bone Cancer Statistics

Bone cancer is rare overall, but it is disproportionately a young person’s cancer, with 34% of cases diagnosed before age 20 and about 1.0 per 100,000 age adjusted incidence in the U.S. Lung is the most common distant metastasis site and survival drops from 71% for localized disease to 27% once it has spread, making the difference between “where it starts” and “where it goes” central to outcomes, with 1,040 new cases and 540 expected deaths in 2024.

Bone cancer is rare, yet it drives a disproportionate share of pediatric cancer diagnoses, with about 3% of all childhood cancers falling into this category. In the U.S., 1,040 new cases are expected in 2024 along with about 540 deaths, and the risk profile changes sharply by age, sex, and stage at diagnosis. We will connect these headline figures to what the data says about major subtypes like osteosarcoma and Ewing sarcoma, and why survival hinges so strongly on whether disease stays localized or spreads.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
