The short answer
SEER reports a 91.9% five-year relative survival rate for breast cancer overall, but that number blends every stage together. Localized breast cancer is 100.0%; cancer that has spread to distant organs is 33.8%. Stage, hormone receptor status, and HER2 status matter more than the single average number.
A survival statistic describes a large group diagnosed years ago — not a prediction for any one person.
For breast cancer, the five-year relative survival rate for everyone combined, diagnosed 2016–2022, was 91.9%.
Stage at diagnosis makes a large difference: localized disease is 100.0% versus 33.8% for distant (metastatic) disease.
Hormone receptor and HER2 status shape treatment and outlook as much as stage does.

The full explanation.
Before you look at the numbers
Three things are true about the numbers below. Read them before you read a single percentage.
First, a "5-year relative survival rate" for breast cancer describes a large group of people. Those people were diagnosed with breast cancer years ago. It is not a prediction about you. Everyone's breast cancer, body, and treatment plan are different.
Second, this data lags behind today's care. These figures reflect people diagnosed with breast cancer between 2016 and 2022. It takes years after diagnosis to know whether someone reached the 5-year mark. So the data is always a few years behind today's treatments. So breast cancer treatment today may already work better than these numbers suggest.
Third, an all-stages number blends very different people together. It mixes people with early, easy-to-treat cancer with people whose cancer had already spread. For breast cancer, the stage-specific numbers below beat one blended average. And "5-year" is just a measurement window researchers use for consistency. It is not a life expectancy for anyone with breast cancer. It is not a deadline either.
The SEER numbers for breast cancer
SEER's most recent report covers people diagnosed with breast cancer between 2016 and 2022. Across every stage combined, the five-year relative survival rate was 91.9%. Breast cancer caught early looks very different from breast cancer caught late. That is why the numbers below matter more than this single average.
About 64% of breast cancers are found at the localized stage, when survival is highest.
| Stage at diagnosis | 5-year relative survival |
|---|---|
| Localized — confined to the breast | 100.0% |
| Regional — spread to nearby lymph nodes | 87.5% |
| Distant — spread to other parts of the body | 33.8% |
| Unknown/unstaged | 70.6% |
What "relative survival" actually means
Relative survival compares two groups. One is people with breast cancer. The other is people in the general population who are the same age and sex but do not have cancer. Say the relative survival rate is 100%. That means people with the cancer were, as a group, about as likely to be alive at 5 years as people without it. It is not the same as the share of people who are cancer-free. And it is not the share of people who die from the cancer itself.
Modern breast cancer staging looks at more than size and spread. It also looks at hormone receptor status, meaning estrogen and progesterone receptors. And it looks at HER2 status. Two people with the same SEER stage can have very different biology because of these markers. They can also have very different treatment plans.
What actually changes your outlook
A statistic describes a group. Your own outlook depends on things specific to you:
- Stage — how far the breast cancer has spread, as shown in the table above.
- Grade — how abnormal the cancer cells look under a microscope, and how fast they tend to grow.
- Hormone receptor status — whether the cancer is fed by estrogen or progesterone.
- HER2 status — whether the cancer makes extra copies of a protein called HER2, which changes treatment options.
- How your cancer responds to treatment — early scans and lab results often tell your care team more than the statistics at diagnosis do.
- Your overall health — other medical conditions, age, and general fitness all affect treatment options and recovery.
- Access to care — timely diagnosis, specialist care, and the ability to complete treatment all matter.
Questions for your care team
- Which SEER stage describes my breast cancer, and what is its five-year number?
- Which biomarkers or molecular tests matter in breast cancer, and were they run on my sample?
- How do my age and overall health change these breast cancer statistics for me?
- Are there newer breast cancer treatments available now that this data doesn't reflect yet?
- Beyond the general breast cancer statistics, what does my team expect in my case?
- Where can I find support for how it feels to hear these breast cancer numbers?
- What is my hormone receptor and HER2 status, and how does it affect my outlook?
If these numbers are hard to sit with
You may feel scared, numb or overwhelmed after reading survival statistics. That is a normal reaction. It does not mean you are handling a breast cancer diagnosis the wrong way. Many people find it easier to take these numbers in slowly, with someone else in the room. Others skip the numbers altogether until they are ready. Cancer Anxiety and Uncertainty covers the fear these breast cancer numbers can stir up. It is also worth telling your breast cancer team how much detail you want, and when.

Common questions
What does 91.9% five-year relative survival mean for breast cancer?
It means that, on average, people diagnosed with breast cancer between 2016 and 2022 were about 91.9% as likely to be alive 5 years later as people of the same age and sex without breast cancer. It blends every stage together, from early to advanced.
Why is the stage-specific number so different from the overall number?
The overall number blends people found early, when breast cancer is most treatable, with people found later. Stage makes a large difference — see the table above. Localized breast cancer usually has a much higher five-year relative survival than distant (metastatic) disease.
Does this number predict what will happen to me?
No. This is a statistic about a large group of people, not a prediction about you. Your age, overall health, tumor biology, and how your breast cancer responds to treatment all shape your individual outlook in ways a group statistic cannot capture.
Is this the most current data available?
It is the most recent data SEER has published, but it still reflects people diagnosed in 2016–2022. Treatments keep changing, so people diagnosed today may do better than these numbers suggest.
Does hormone receptor or HER2 status change these numbers?
Yes. SEER's headline numbers combine every subtype. Hormone receptor-positive, HER2-negative breast cancer generally follows a different course than triple-negative or HER2-positive disease. Ask your care team how your specific subtype affects your outlook.
