How much has the U.S. cancer death rate dropped?

By 35% between 1991 and 2024, according to the AACR Cancer Progress Report — translating into more than 4.8 million cancer deaths averted compared with the old rates.

Is the progress the same for all cancers and groups?

No. Mortality reductions vary by cancer type — lung cancer dropped sharply while colorectal and breast cancer declined less — and the report stresses persistent disparities by race, income and geography, meaning the gains have not reached everyone equally.

U.S. Cancer Death Rate Down 35% Since 1991, 4.8M Lives Saved (AACR)

Q: Why did cancer deaths decline?

The AACR credits decades of federal research investment plus three main forces: falling smoking rates, earlier detection through screening, and better treatments (including targeted therapy and immunotherapy). Lung cancer deaths, for example, fell about 4.2% per year from 2015 to 2024.

A new report finds the American cancer death rate has dropped by more than a third over three decades — the result of less smoking, earlier detection and better treatment — even as new challenges loom.

Amid a steady drumbeat of worrying health news, here is a genuinely hopeful figure: the U.S. cancer death rate has fallen by 35% since 1991, an improvement that translates into more than 4.8 million cancer deaths averted, according to the American Association for Cancer Research (AACR).

What the numbers show

The AACR Cancer Progress Report found the overall cancer death rate dropped 35% between 1991 and 2024. That percentage can feel abstract, but the human meaning is not: 4.8 million people who would have died of cancer under the old rates are alive — parents, grandparents, friends — because the trajectory bent downward. Survival has improved too: across all cancers, the five-year survival rate for distant-stage (spread) disease more than doubled, from about 17% in the mid-1990s to 36% in 2016–2022.

Why the decline happened

Progress this broad has many parents. The AACR credits decades of federal investment in research and public health — through the NIH, National Cancer Institute, FDA and CDC — that seeded the science behind modern prevention and treatment. Three forces stand out: falling smoking rates (which drove down lung and other tobacco-related cancers), earlier detection through screening, and better treatments, from targeted therapies to immunotherapy. Lung cancer illustrates the payoff: its death rate fell about 4.2% per year from 2015 to 2024, a remarkable pace.

The uneven picture

The gains are real but not uniform. Reductions in mortality vary widely by cancer type — lung cancer’s steep drop contrasts with smaller declines in colorectal and female breast cancer. Some cancers remain stubbornly hard to treat, and progress against them has lagged. The report also emphasizes persistent disparities: the benefits of this progress have not reached everyone equally, with gaps by race, income and geography.

The road ahead

Even with the decline, cancer remains an enormous burden. The AACR projects that in 2026, the U.S. will see about 2.1 million new cancer diagnoses and 626,140 cancer deaths. And demographics push the other way: as the population grows and ages, the total number of cases rises even as the rate of death falls. Sustaining progress will require continued investment — a point the report underscores at a time of budget pressure on research agencies.

Why it matters

It’s easy to lose sight of long-run progress amid daily headlines, but a 35% drop in cancer death rates is one of the great public-health achievements of the past generation — proof that research, prevention and policy compound over time. The lesson is twofold: the tools that drove the decline (reducing smoking, screening, better treatment, sustained funding) work, and the job is unfinished — for the cancers still winning, and for the communities the gains have not fully reached.
