Fifty years ago, a cancer diagnosis meant a roughly one-in-two chance of surviving five years. Today, that number has crossed 70% — and the American Cancer Society's landmark 2026 report confirms it is real, sustained, and accelerating.
The Cancer Statistics 2026 report, one of the most comprehensive annual assessments of America's cancer burden, reveals that the five-year relative survival rate for all cancers combined now stands at 70% for patients diagnosed between 2015 and 2021. That is up from 49% in the mid-1970s — a 21-percentage-point gain that represents hundreds of thousands of lives saved every year.
'Seven in 10 people now survive their cancer five years or more, up from only half in the mid-70s,' said Rebecca Siegel, Senior Scientific Director of Surveillance Research at the ACS. 'It's a milestone we should all pause to recognise.'
The gains are not confined to a few easy-to-treat cancers. They are visible across the spectrum — including myeloma, liver cancer, and metastatic melanoma, diseases that were once considered near-certain death sentences within months of diagnosis.
The driving forces are decades of scientific investment bearing fruit simultaneously. Immunotherapy — training the body's own immune system to target and destroy cancer cells — has been transformative for melanoma, lung, kidney, and bladder cancers. Targeted therapies match treatments to the specific genetic mutations driving each patient's tumour, delivering precision strikes where older chemotherapy sprayed destruction broadly.
Earlier detection has also made a profound difference. Better screening means cancers are caught when they are smaller, localised, and far more treatable. Declines in smoking rates, the single largest preventable cause of cancer, have driven down lung cancer incidence over decades.
The progress is particularly striking in cancers that historically offered the bleakest prognosis:
— Metastatic melanoma, once survivable for a median of less than a year, now sees many patients living five years or beyond on immunotherapy. — Chronic myeloid leukaemia, once managed only through bone marrow transplant, is now controlled by daily oral pills for most patients — with near-normal life expectancy. — Childhood cancers overall now have survival rates exceeding 85%.
The 2026 report also projects approximately 2.1 million new cancer diagnoses in the United States this year — a number that reflects both growing and ageing population alongside improved detection, not a worsening of cancer rates. Cancer death rates have in fact declined by 34% since 1991.
The ACS notes that continued progress depends on protecting federal research funding and ensuring treatment access across all communities — gaps that remain real even as the headline number climbs.
But for the 18 million American cancer survivors alive today, and the millions more around the world, the number tells a story that deserves to be told plainly:
For the first time in recorded history, if you are diagnosed with cancer in the United States, the odds are now in your favour. ❤️
