Vulvar Cancer Statistics

With about 6,470 new invasive vulvar cancer cases expected in the US in 2023, the numbers already hint at how unevenly this disease affects people by age, race, and region. From global estimates of 45,000 new cases in 2020 to US incidence of 2.5 per 100,000 women and rising trends in Black women, the patterns are complex and worth unpacking. This post brings the full statistical picture together, including risk factors, early detection rates, and survival outcomes.

Treatment and Outcomes Interpretation

While survival rates shine brightly for early, localized cases, the journey through advanced vulvar cancer reveals a sobering landscape of escalating interventions and diminishing odds, starkly highlighting that prevention and earliest possible detection are the truest victories.

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
