About 70% of people diagnosed with cancer in the United States survive at least five years, up from 49% in the mid-1970s. That translates to roughly 18.1 million Americans currently living with a history of cancer. But “how many survive” depends enormously on the type of cancer, when it’s caught, where in the world someone lives, and their age at diagnosis.
Overall Survival Rates Today
The five-year survival rate for all cancers combined sits at 70% for people diagnosed between 2015 and 2021, based on data from the National Cancer Institute’s SEER program. That’s a 21-percentage-point jump from the late 1970s, driven by earlier detection, better surgical techniques, targeted therapies, and immunotherapy. Ten-year survival tells a similar story: Australian data from 2013 to 2017 puts it at 64% across all cancer types combined.
These are “relative” survival figures, which means they filter out deaths from other causes. If someone with cancer dies in a car accident or from heart disease, that death doesn’t count against the cancer survival rate. The number reflects the likelihood of surviving cancer specifically, compared to someone of the same age and sex without cancer.
Survival Varies Widely by Cancer Type
The 70% overall figure masks a huge range. Some cancers are highly survivable. Others remain stubbornly lethal.
- Prostate cancer: 98% five-year survival in the U.S., 92% at ten years. Most prostate cancers grow slowly, and many men diagnosed with it die of something else entirely.
- Breast cancer (women): 90% five-year survival in the U.S., 86% at ten years. Screening mammography and hormone-blocking treatments have pushed these numbers steadily upward.
- Lung cancer: 19% five-year survival in the U.S., 14% at ten years. Lung cancer is often diagnosed late, which explains the gap between it and cancers caught earlier.
- Pancreatic cancer: Just 9% ten-year survival. Pancreatic tumors rarely cause symptoms until they’ve spread, making early detection extremely difficult.
Melanoma (89% at ten years), thyroid cancer, and testicular cancer also fall on the highly survivable end. Cancers of the liver (15% at ten years), brain (17%), and esophagus (18%) cluster near the bottom alongside lung and pancreatic cancers.
Why Stage at Diagnosis Matters So Much
Perhaps the single biggest factor in whether someone survives cancer is how far it has spread when doctors find it. Lung cancer illustrates this starkly: 61% of people diagnosed with early-stage lung cancer live at least five years, compared to just 7% of those diagnosed after it has spread to distant parts of the body. That’s nearly a ninefold difference for the same disease.
This pattern holds across almost every cancer type. Localized cancers, those still confined to the organ where they started, respond better to surgery and radiation because the entire tumor can often be removed. Once cancer cells travel through the bloodstream or lymphatic system to distant organs, treatment shifts from cure to control, and survival drops sharply. It’s why screening programs for breast, cervical, colorectal, and lung cancers exist: catching tumors before they spread saves lives at a population level.
Children Survive at Higher Rates
Childhood cancers have seen some of the most dramatic survival gains in modern medicine. In the mid-1970s, 58% of children under 14 survived at least five years. Today that figure ranges from 83% to 88% depending on age group, with children ages 1 to 4 faring best at nearly 88%.
Certain childhood cancers have been transformed from near-certain death to highly curable diseases. Acute lymphoblastic leukemia, the most common childhood cancer, went from 57% five-year survival in 1975 to over 92% by 2014 to 2020. Non-Hodgkin lymphoma in children jumped from 43% to over 91% in the same period. These improvements came largely from refining chemotherapy combinations and learning how to sequence treatments more effectively.
Adolescents ages 15 to 19 also do well overall, with five-year survival around 87%. One interesting finding: adolescents and young adults with leukemia tend to have better outcomes when treated with protocols designed for children rather than those designed for adults.
Survival Differs Around the World
Where you live changes your odds considerably. The CONCORD-3 study, which tracked cancer survival across 71 countries from 2000 to 2014, found that five-year survival remains highest in the U.S., Canada, Australia, New Zealand, and the Nordic countries.
The gaps can be striking. Breast cancer five-year survival is about 90% in the U.S. and Australia but drops to 66% in India. For childhood leukemia, five-year survival ranges from under 50% in Ecuador to over 95% in Finland. Brain tumors in children show a spread from 29% in Brazil to nearly 80% in Sweden and Denmark. These disparities reflect differences in access to screening, the availability of specialized cancer centers, time to diagnosis, and whether patients can afford and access the full course of treatment.
The Growing Population of Survivors
Because more people are surviving and because the population is aging (which means more people are getting cancer in the first place), the number of cancer survivors keeps climbing. The current estimate of 18.1 million Americans living after a cancer diagnosis is projected to reach 22.4 million by 2035. The number who have survived five or more years past diagnosis is expected to grow by 53% between 2022 and 2040, reaching 19.2 million.
This growing population has shifted how doctors think about cancer care. Survivorship is now its own medical focus, addressing the long-term side effects of treatment, the risk of second cancers, and the psychological toll of diagnosis. For the majority of people diagnosed with cancer today, the question is increasingly not just whether they’ll survive, but what life looks like afterward.
