Life expectancy for people with metastatic or metastasized lung cancer is low. The 5-year survival rate for small cell lung cancer is 3%, and 8% for non-small cell lung cancer (NSCLC). 25-30% of people with metastatic NSCLC have a life expectancy of under 3 months.
Survival rates for metastatic lung cancer are estimates. Several factors, including age and overall health, can affect a person’s outlook.

Researchers base cancer survival rates on the type of cancer, the subtype of cancer, and the stage at diagnosis. When considering the 5-year survival rate for metastatic lung cancer, looking at the subtype of the cancer can also help determine the overall survival rate.
According to the American Lung Association (ALA), lung cancer is the leading cause of death among people with cancer, accounting for 25% of all cancer fatalities. They state that the overall 5-year survival rate is now about 18.6%.
Though still low compared to other cancers, this rate represents an improvement. In a
Sex, age, and race differences
Lung cancer death rates are not equal across sexes and races. The ALA state that Black people die from lung cancer at a higher rate than other racial groups. The age-adjusted mortality rate for Black men is also higher than that for white men.
These disparities may be due to inequities in healthcare.
A person’s age at diagnosis may also influence survivability rates. According to the
Non-small cell lung cancer (NSCLC)
NSCLC is the most common type of lung cancer, representing about
There are several subtypes of NSCLC. These include:
- large cell carcinoma
- squamous cell carcinoma
These subtypes are grouped together as NSCLC due to having similar outlooks, treatments, and survivability rates.
Small cell lung cancer
Small cell lung cancer accounts for
According to the
Lung cancer that spreads to the bones
The location of metastasis may also affect a person’s survival rate.
For example, in one
Survival rates are generalized markers that indicate the likelihood that a person will live after a set period of time. Often, doctors and other researchers look at the 5-year survival rate.
According to the
These rates may help a person better understand how well the treatment may work for them, but they cannot tell a person exactly how long they will live.
In other words, if a person receives a diagnosis of stage 1 lung cancer first and then metastatic lung cancer later, their survival rate relates to their new diagnosis.
Several factors can influence a person’s survival likelihood, including:
- their age
- their overall health
- genetic changes in the cancer cells
- subtype of NSCLC
- how effective treatment is
Survival rates are also constantly changing. Newer treatments are often more effective, and better treatment options may improve a person’s chance of survival.
Lung cancer has a relatively low 5-year survival rate compared with other cancers, and it is the leading cause of death from cancer. Age, sex, and health inequities related to race can affect the numbers.
It is important to remember that the survival rate does not mean a person will live or die in 5 years. A person should talk with a doctor about their outlook. They can explain the factors affecting them and recommend treatments to prolong survival.
