Lung Cancer Rates

New Cases

New Cases:

  • The rate of new lung cancer cases in Montana is 44.7 and significantly lower than the national rate of 52.1.
  • It ranks 11th among all states, placing it in the above average tier.
  • Over the last five years, the rate of new cases in Montana improved by 18%.
  • Note: When examining incidence data, it is important to note that the COVID-19 pandemic disrupted access to medical care. This resulted in a drop in cancer diagnoses for the year 2020, particularly for cancers diagnosed before symptoms develop (including lung cancer). This drop reflects changes in medical care for 2020 and should not necessarily be interpreted as a reduction in the underlying cancer burden.
5-Year Survival Rate

Five-Year Survival Rate:

  • The percent of people living five years after being diagnosed with lung cancer (the survival rate) in Montana is 30.3%, which is not significantly different than the national rate of 31.0%.
  • It ranks 23rd among the 43 states with survival data, placing it in the average tier.
  • Over the last five years, the survival rate in Montana improved by 25%.
Stage at Diagnosis

Most lung cancer cases are diagnosed at later stages when the cancer has spread to other organs, treatment options are less likely to be curative, and survival is lower. The earlier lung cancer is diagnosed, the more likely treatments will be curative and improve chances of survival.

Nationally, 42.6% of cases are not caught until a late stage when the survival rate is only 12%.

Early Diagnosis:

  • In Montana, 31.4% of cases are caught at an early stage, which is significantly higher than the national rate of 29.3%.
  • It ranks 13th among the 47 states with data on diagnosis at an early stage, placing it in the above average tier.
  • Over the last five years, the early diagnosis rate in Montana did not change significantly.

Lung Cancer Treatment

Biomarker Coverage

Biomarkers are clues that physicians look for in tumor tissue and blood that help healthcare providers understand what is driving a person’s lung cancer and which treatment options might be most appropriate for an individual’s specific tumor makeup. Comprehensive biomarker testing and its results are important in helping determine if targeted treatment options, as well as immunotherapy, are appropriate for individuals with lung cancer. Insurance coverage of such testing is important for removing a cost barrier to lung cancer patients but is only required in some states.

 

Biomarker Coverage:

  • Montana has yet to require any insurance coverage of comprehensive biomarker testing, including for lung cancer, as of September 2026.
Surgical

While surgery may not be an option for every patient, those who receive it as part of their initial treatment have higher survival rates than those who do not. Surgery to remove lung cancer is not an appropriate treatment option for all patients. Other treatments may be recommended instead of or in addition to surgery, such as chemotherapy, radiation, targeted therapy or immunotherapy.

Surgical Treatment:

  • Montana ranked 24th (out of the 40 states with available data) with 19.7% of cases undergoing surgery as part of the first course of treatment.
  • This is significantly lower than the national rate of 21.4% and puts Montana in the average tier.
Lack of Treatment

Not every person receives treatment after being diagnosed with lung cancer. This can happen for multiple reasons, such as poor health or refusal of treatment. Some of these reasons may be unavoidable, but no one should go untreated because of lack of provider or patient knowledge, lung cancer stigma, fatalism after diagnosis, or cost of treatment. Dismantling these barriers is important to reducing the percentage of people who do not receive any treatment.

No Treatment:

  • Montana ranked 32nd (out of the 47 states with available data) with 21.6% of cases not receiving any treatment.
  • This is not significantly different than the national rate of 20.9% and puts Montana in the average tier.

Screening

High Risk

Screening for lung cancer with annual low-dose CT scans among those at high risk, as determined by the United States Preventive Services Task Force (USPSTF), can reduce the lung cancer death rate by up to 20% by detecting the disease at early stages when it is more likely to be curable.

High Risk is defined as:

USPSTF Guidelines 2021-present
Age 50-80 years (Medicare only covers screening up to age 77)
Smoking History 20 or more pack years
(this means 1 pack a day for 20 years, 2 packs a day for 10 years, etc.)
Currently smoke or quit within the last 15 years

Screening for High Risk:

  • In Montana, 23.6% of those at high risk were screened, which was not significantly different than the national rate of 24.4%.
  • It ranks 27th (out of the 50 states with available data), placing it in the average tier.

For screening to be most effective in reducing the overall lung cancer mortality rate, more of the high-risk population should be screened—currently screening rates are very low among those at high risk. This may be because of a lack of access or low awareness and knowledge among patients and providers. Rates vary tremendously between states and more can be done to increase screening rates.

Prevention

Tobacco
​
Tobacco use is the leading risk factor for lung cancer. Smoking and secondhand smoke have both been shown to cause lung cancer.

State of Tobacco Control

Each year the Lung Association publishes the "State of Tobacco Control" report. The 2026 report grades the federal government and all 50 states on key tobacco control policies. States are graded in five policy areas: tobacco control and prevention spending, smokefree air, tobacco taxes, access to cessation services and flavored tobacco prohibitions.

Tobacco Use:

  • The 2025 smoking rate in Montana is 12.2% and significantly higher than the national rate of 10.4%.
  • It ranks 35th (out of the 48 states with available data), placing it in the below average tier.
Radon
​
Radon is the second leading cause of lung cancer.
Radon is a colorless and odorless gas that can seep into homes and buildings. Some geographical areas naturally have higher average radon levels than others, but because any home can be at risk for elevated levels, the only way to know is to do a test. If testing shows interior radon levels at or above the U.S. EPA action level of 4 pCi/L (picoCuries per liter of air) or higher, it is recommended to take corrective measures to reduce your exposure to radon gas. Such measures should also be considered at levels at or above 2 pCi/L.

Radon:

  • In Montana, 45.6% of radon tests results were at or above the action level recommended by EPA.
  • It ranks 44th among all states, placing it in the bottom tier.
Air Pollution
​
Air pollution is a known risk factor for lung cancer. Long-term exposure to outdoor particle pollution is known to cause lung cancer.

State of the Air

Each year the Lung Association publishes the "State of the Air" report. The 2026 report grades U.S. counties on harmful particle pollution and ozone pollution recorded over a three-year period, and details trends for metropolitan areas over the past two decades. The report also ranks the cleanest and most polluted areas in the country.

  • 12.1% of Indigenous peoples (American Indians/Alaska Natives) with lung cancer in Montana underwent surgery, not significantly different than the rate of 15.8% among Indigenous peoples (American Indians/Alaska Natives) nationally, and significantly lower than the rate of 20.3% among white individuals in Montana. 
  • 24.1% of Indigenous peoples (American Indians/Alaska Natives) with lung cancer in Montana did not receive any treatment, not significantly different than the rate of 24.7% among Indigenous peoples (American Indians/Alaska Natives) nationally, and not significantly different than the rate of 21.7% among white individuals in Montana.

Summary

Despite the early diagnosis rate in Montana falling into the above average tier, the state still has a lot of work to do to make sure that more of those at high risk for lung cancer are screened.

Montana has yet to require any insurance coverage of comprehensive biomarker testing, which can help determine what treatment options would be best for individuals with lung cancer and other diseases.

Montana falls into the average tier for percent of patients receiving no treatment. Some patients do refuse treatment, but issues such as fatalism and stigma can prevent eligible patients from accessing treatment that may save or extend their lives. All patients should work with their doctors to establish a treatment plan and goals.

What Can I Do?

You can lower their risk of lung cancer, as well as the risk of those around you, through these steps:

Take Action

All new lung cancer discoveries approved and recommended today have been studied in clinical trials, including lung cancer screening and treatment advances. Urge Congress to support the bipartisan Clinical Trial Modernization Act (H.R. 3521/S. 4440) to make clinical trials more accessible, including for people with lung cancer.

Take Action
  • Encourage others who meet the criteria to do the same.
  • If you or someone you know is ready to quit smoking, the Lung Association is here to help. Our Freedom From Smoking program has helped over a million people quit smoking for good.
  • Support comprehensive and strong tobacco control policies, including:
    • Higher tobacco taxes, which both encourage people to quit and prevent children and others from starting to smoke.
    • Adequate funding of tobacco control programs, which are an important part of helping people quit and keeping new people from starting.
    • Comprehensive coverage of all FDA-approved smoking cessation medication and the three forms of counseling, with no barriers to accessing them, which leads to more successful quit attempts.
  • Make your house and car clean air zones, with no smoking allowed. Avoid places that are not smokefree, and advocate for smokefree air policies in restaurants, bars, casinos or anywhere they are not in place.

Radon is a naturally occurring gas that can have a big impact on indoor air quality and your health. Take steps to reduce your risk if radon levels in your home are too high.
