The short answer
SEER reports a 29.5% five-year relative survival rate for lung cancer overall, mostly because lung cancer is often found late. Localized lung cancer is 65.5%; distant (metastatic) disease is 10.5%. Molecular testing now shapes treatment and outlook far more than it did even a few years ago.
A survival statistic describes a large group diagnosed years ago — not a prediction for any one person.
For lung cancer, the five-year relative survival rate for everyone combined, diagnosed 2016–2022, was 29.5%.
Stage at diagnosis makes a large difference: localized disease is 65.5% versus 10.5% for distant (metastatic) disease.
Molecular testing (EGFR, ALK, PD-L1, and others) increasingly shapes both treatment and outlook.

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 lung cancer describes a large group of people. Those people were diagnosed with lung cancer years ago. It is not a prediction about you. Everyone's lung cancer, body, and treatment plan are different.
Second, this data lags behind today's care. These figures reflect people diagnosed with lung cancer between 2016 and 2022. Targeted drugs and immunotherapy for lung cancer have changed a lot in recent years. So this data does not fully reflect current options. So lung 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 lung 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 lung cancer. It is not a deadline either.
The SEER numbers for lung cancer
SEER's most recent report covers people diagnosed with lung and bronchus cancer between 2016 and 2022. Across every stage combined, the five-year relative survival rate was 29.5%. That low overall number reflects how often lung cancer is found after it has already spread. It does not reflect how treatable early lung cancer can be.
Screening with low-dose CT scans is the main tool that finds lung cancer while it is still localized. It is offered to people who qualify.
| Stage at diagnosis | 5-year relative survival |
|---|---|
| Localized — confined to the lung | 65.5% |
| Regional — spread to nearby lymph nodes | 38.2% |
| Distant — spread to other parts of the body | 10.5% |
| Unknown/unstaged | 17.5% |
What "relative survival" actually means
Relative survival compares two groups. One is people with lung 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.
Lung cancer treatment now depends heavily on molecular testing. Mutations such as EGFR or ALK can open up targeted drugs. So can a marker called PD-L1, which points toward immunotherapy. None of those existed when older survival data was collected. Ask whether your tumor has been tested for these markers.
What actually changes your outlook
A statistic describes a group. Your own outlook depends on things specific to you:
- Stage — how far the lung 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.
- Cancer type — small cell versus non-small cell lung cancer are treated very differently.
- Molecular markers — mutations like EGFR, ALK, or KRAS, and PD-L1 level, can open up targeted or immune-based treatment.
- 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 lung cancer, and what is its five-year number?
- Which biomarkers or molecular tests matter in lung cancer, and were they run on my sample?
- How do my age and overall health change these lung cancer statistics for me?
- Are there newer lung cancer treatments available now that this data doesn't reflect yet?
- Beyond the general lung cancer statistics, what does my team expect in my case?
- Where can I find support for how it feels to hear these lung cancer numbers?
- Has my tumor been tested for EGFR, ALK, or other targetable mutations, and what was the PD-L1 result?
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 lung 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 lung cancer numbers can stir up. It is also worth telling your lung cancer team how much detail you want, and when.

Common questions
What does 29.5% five-year relative survival mean for lung cancer?
It means that, on average, people diagnosed with lung cancer between 2016 and 2022 were about 29.5% as likely to be alive 5 years later as people of the same age and sex without lung 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 lung cancer is most treatable, with people found later. Stage makes a large difference — see the table above. Localized lung 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 lung 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.
Why is the overall lung cancer survival number so much lower than other cancers?
Mostly because lung cancer often causes no symptoms until it has spread. Only a minority of cases are found at the localized stage. Lung cancer screening for people at high risk is meant to catch more cancers earlier, when survival is much higher.
