For the first time in recorded medical history, more than 70% of people diagnosed with cancer in the United States survive at least five years — a milestone that reflects decades of advances in early detection, treatment, and survivorship care. The figure, drawn from national surveillance data, marks a profound shift in what a cancer diagnosis means for millions of Americans.
At a glance
- Cancer survival rate: The overall U.S. five-year relative survival rate has crossed 70% for the first time, up from roughly 50% in the 1970s.
- Cancer deaths avoided: The American Cancer Society estimates that more than 4 million cancer deaths were averted between 1991 and 2022 C.E., largely due to declining smoking rates, earlier screening, and improved therapies.
- Survival leaders: Cancers with the steepest improvements include breast, prostate, and certain leukemias — with some subtypes now approaching 90% or higher five-year survival.
How we got here
The climb from 50% to 70% didn’t happen overnight. It reflects a half-century of compounding gains across the entire cancer care pipeline.
Screening programs caught more cancers earlier, when they are most treatable. Mammography, colonoscopy, and low-dose CT scans for lung cancer have each contributed to stage shifts — meaning more people are diagnosed at stage I or II rather than stage III or IV. Earlier-stage cancers are dramatically more survivable.
At the same time, treatment options expanded enormously. Immunotherapy reshaped outcomes for melanoma and lung cancer. Targeted therapies matched to specific genetic mutations turned some previously fatal diagnoses into manageable conditions. And supportive care — nutrition, mental health, pain management — improved patients’ ability to complete treatment.
The role of data and research infrastructure
Behind the number is a vast data infrastructure. The National Cancer Institute’s SEER program (Surveillance, Epidemiology, and End Results) has tracked cancer outcomes across the U.S. population since 1973 C.E., enabling researchers to identify which interventions work and for whom.
The American Cancer Society’s annual Cancer Statistics report, published in CA: A Cancer Journal for Clinicians, synthesizes this data and has become a benchmark document for oncologists, policymakers, and public health advocates worldwide. The most recent editions documented the crossing of the 70% threshold, drawing on data from the NCI, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries.
This kind of long-term data collection — often unglamorous, expensive, and invisible to the public — is precisely what makes breakthroughs legible. Without it, we wouldn’t know what’s working.
Who is still being left behind
The 70% figure is a national average, and averages conceal as much as they reveal. Black Americans continue to face higher cancer mortality rates than white Americans across several cancer types, a gap driven by unequal access to screening, later-stage diagnoses, and systemic barriers to care. Pancreatic, liver, and lung cancers — which disproportionately affect certain communities — still carry five-year survival rates well below 30%.
Researchers and advocates have been direct about this: reaching 70% overall while leaving gaps of 20 to 30 percentage points by race and cancer type is not a finished story. The NCI’s Center to Reduce Cancer Health Disparities funds targeted research into these inequities, but progress has been uneven.
Geography also matters. Rural Americans are less likely to have access to specialized cancer centers, clinical trials, or the full range of treatment options available in metropolitan areas. Closing these gaps is the next frontier of the survival story.
What the milestone signals
A 70% survival rate would have seemed almost utopian to oncologists practicing in the 1970s C.E. It is worth pausing on that.
It means that the majority of people who hear the words “you have cancer” will, statistically, be alive five years later. It means that the roughly 2 million Americans diagnosed each year now have better odds than any cancer patient in history. And it means that the research investments, public health campaigns, and clinical innovations of recent decades are paying off in measurable human lives.
Survivorship itself has become a field of medicine. The American Society of Clinical Oncology now publishes guidelines specifically for life after cancer — managing long-term side effects, monitoring for recurrence, and supporting the psychological dimensions of surviving. The community of cancer survivors in the U.S. now numbers more than 18 million people.
The 70% threshold is a beginning, not a ceiling. Researchers are already targeting 80%, with trials underway in precision medicine, early liquid biopsies, and AI-assisted diagnostics. The arc bends toward more people surviving — and surviving well.

Marie-Louise Eta becomes first female head coach in men’s top-five European leagues
Female head coach Marie-Louise Eta made history on April 11, 2026, when Union Berlin appointed her as interim head coach — becoming the first woman ever to hold a head coaching position in any of men’s top-five European leagues. The Bundesliga club made the move after dismissing Steffen Baumgart, with five matches remaining and real relegation stakes on the line. Eta, 34, had served as assistant coach since 2023 and was already a familiar, trusted presence within the squad. This was no ceremonial gesture — she was handed a survival fight, which is precisely what makes the milestone significant. The…

Renewables hit 49% of global power capacity for the first time
Renewable energy capacity crossed a landmark threshold in 2025, with global installed power surpassing 5,100 gigawatts and representing 49% of all capacity worldwide for the first time in history. The International Renewable Energy Agency reported a single-year addition of 692 gigawatts, led overwhelmingly by solar power, which alone accounted for 75% of new renewable installations. Clean energy now represents 85.6% of all new power capacity added globally, signaling that the transition has moved from aspiration to economic reality. The milestone carries implications beyond climate — nations with strong renewable bases demonstrated measurably greater energy security amid ongoing geopolitical instability.

Global suicide rate has dropped nearly 40% since the 1990s
Global suicide rates have dropped nearly 40% since the early 1990s, falling from roughly 15 deaths per 100,000 people to around nine — one of modern public health’s most significant and underreported victories. This decline was driven by expanded mental health services, crisis intervention programs, and proven strategies like restricting access to lethal means. The progress spans dozens of countries, with especially sharp declines in East Asia and Europe. Critically, this trend demonstrates that suicide is preventable at a population level — making the case for sustained investment in mental health infrastructure worldwide.
