Cancer Statistics - 2026-2028 Source Check

Under scientific review

This introductory page is under scientific review. Use it for orientation, not clinical decision-making.

Last checked: 2026-05-22. This page keeps the legacy route name for now, but the visible title and content use the current 2026-2028 source cycle. Do not treat any survival or incidence number here as an individual prognosis.

TL;DR

Cancer statistics are population-level estimates. They are useful for planning, prevention, screening policy, registry work, trial design, and public-health priorities. They are not enough to predict what will happen to one person, because outcome depends on tumor type, stage, biology, treatment access, comorbidities, and response.

Use current official sources before copying numbers:

Geography / question	Preferred source	Current source note
Global burden	IARC / WHO Global Cancer Observatory	GLOBOCAN 2022 estimates nearly 20 million new cancer cases and 9.7 million cancer deaths worldwide in 2022.
United States estimates	American Cancer Society and NCI / SEER	ACS Cancer Facts & Figures 2026 is the current annual report; SEER provides registry-based incidence, mortality, and survival.
Brazil estimates	INCA Estimativa 2026-2028	INCA estimates about 781,000 new cancer cases per year in Brazil for 2026-2028, or about 518,000 excluding non-melanoma skin cancer.
Survival	SEER, INCA, national registries	Survival is relative to population cohorts and diagnosis periods; it is not a promise for one patient.
Prevention	ACS, WHO/IARC, INCA	Modifiable risk fractions vary by method, country, exposure, and cancer type.

Current anchor numbers

Global

IARC/GLOBOCAN estimates for 2022:

• nearly 20 million new cancer cases worldwide;
• about 9.7 million cancer deaths worldwide;
• lung cancer as the leading cause of cancer death globally, responsible for about 1.8 million deaths.

These are global estimates across 185 countries and 36 cancer types. They are useful for scale, but not for local service planning without country-level data.

Brazil

INCA's current Estimativa 2026: incidência de câncer no Brasil covers the 2026-2028 triennium:

• about 781,000 new cancer cases per year;
• about 518,000 new cases per year when non-melanoma skin cancer is excluded;
• important regional heterogeneity by sex, state, and tumor type.

For Brazil-facing claims, prefer INCA's tables and the source PDF rather than reusing older 2023-2025 numbers.

United States

For U.S. annual projections, use ACS Cancer Facts & Figures 2026 and NCI/SEER. NCI's public statistics page also explains the difference between incidence, mortality, lifetime risk, and survival.

Survival

SEER reports 5-year relative survival for "any cancer site" as 69.9% for the 2015-2021 diagnosis period. This is a population statistic. It does not mean every person has a 69.9% chance, and it should not be used without cancer type, stage, age, and treatment context.

How not to misuse statistics

• Do not compare countries without checking age standardization.
• Do not compare survival across time without considering screening, lead-time bias, overdiagnosis, and treatment access.
• Do not mix global, U.S., and Brazil estimates in the same sentence unless the geography is explicit.
• Do not use "preventable" as blame. Population risk reduction is not individual fault.
• Do not cite a rounded number without a source year.

For technologists

When building dashboards or examples:

1. Store source, geography, sex, age band, year, tumor site, and measure type with every number.
2. Separate estimates from observed registry data.
3. Use confidence intervals when available.
4. Explain whether rates are crude, age-adjusted, or age-standardized.
5. Keep a last_checked date for any public-facing statistic.
