Indigenous Peoples in South Dakota are most likely to be diagnosed with lung cancer.

Lung Cancer Rates

New Cases

New Cases:

  • The rate of new lung cancer cases is 58 and not significantly different than the national rate of 58.
  • South Dakota ranks 23rd among all states, placing it in the average tier.
  • Over the last five years, the rate of new cases did not change significantly.
5-Year Survival Rate

5-Year Survival Rate:

  • The percent of people alive five years after being diagnosed with lung cancer (the survival rate) in South Dakota is 25%, which is not significantly different than the national rate of 24%.
  • It ranks 15th among the 45 states with survival data, placing it in the average tier.
  • The change in the survival rate over the last five years is not available for South Dakota.
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. In general, the earlier that lung cancer is diagnosed, the more likely that treatments will be effective and improve chances of survival.

Nationally, only 24% of cases are caught early when the five-year survival rate is much higher (60%). Unfortunately, most cases (46%) are not caught until a late stage when the survival rate is only 6%.

Early Diagnosis:

  • 26% of cases are caught at an early stage, which is not significantly than the national rate of 24%.
  • It ranks 13th among the 49 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 South Dakota improved by 44%.

Lung Cancer Treatment

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. Patients who are not healthy enough to undergo the procedure or whose cancer has spread too far, may not be candidates for surgery. Other treatments may be recommended instead of or in addition to surgery, such as chemotherapy, radiation, targeted therapy or immunotherapy.

Surgical Treatment:

  • South Dakota ranked 44th (out of the 49 states with available data) with 16% of cases undergoing surgery as part of the first course of treatment.
  • This is significantly lower than the national rate of 20.7% and puts South Dakota in the bottom tier.
  • Over the last five years, the percent of cases undergoing surgery in South Dakota did not change significantly.
Lack of Treatment

Not every patient 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, stigma associated with lung cancer, fatalism after diagnosis, or cost of treatment. Dismantling these and other barriers is important to reducing the percent of patients who do not receive any treatment.

Lack of Treatment:

  • South Dakota ranked 31st (out of the 49 states with available data) with 21% of cases not receiving any treatment.
  • This is not significantly different than the national rate of 21% and puts South Dakota in the average tier.
  • Over the last five years, the percent of cases receiving no treatment in South Dakota did not change significantly.

Screening

​

COVID-19 Impact

Nationally, screening rates have increased every year since it was first recommended. However, the national rate did not change from 2019 to 2020, likely due to COVID-19 lockdowns limiting access to healthcare resources and the public’s reticence to enter medical facilities during the pandemic.

High Risk

Screening for lung cancer with annual low-dose CT scans among those at high risk can reduce the lung cancer death rate by up to 20% by detecting tumors at early stages when they are more likely to be curable.

Based on new research, in March of 2021, the United States Preventive Services Task Force expanded its recommendation for screening to include a larger age range and more current and former smokers. This will dramatically increase the number of women and Black Americans considered at high risk for lung cancer.

High Risk is defined as:

  2020 Guidelines 2021 Guidelines
Age 55-80 years 50-80 years
Smoking History 30 or more pack years
(this means 1 pack a day for 30 years, 2 packs a day for 15 years, etc.)		 20 or more pack years
(this means 1 pack a day for 20 years, 2 packs a day for 10years, etc.)
Smoking Status Current smoker or quit within the last 15 years

Screening rates in this report are from before the guidelines were updated and do not yet reflect screening among those newly eligible.

Screening for High Risk:

  • In South Dakota, 10% of those at high risk were screened, which was significantly higher than the national rate of 6%.
  • It ranks 9th among all states, placing it in the above 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.

Medicaid Coverage

Medicaid beneficiaries are disproportionately affected by lung cancer, yet standard Medicaid programs are one of the only healthcare payers not required to cover lung cancer screening. If screening is covered, Medicaid programs may use different eligibility criteria, require prior authorization or charge individuals for their scans. The American Lung Association analyzed lung cancer screening coverage policies in state Medicaid fee-for-service programs to assess the current status of lung cancer screening coverage for the Medicaid population.

The Lung Association urges all state Medicaid programs to cover lung cancer screening based on evidence-based guidelines across all fee-for-service and managed care plans and to remove any financial or administrative barriers that limit access to this lifesaving service.

Medicaid Coverage:

  • South Dakota was one of the 40 states whose Medicaid fee-for-service programs covered lung cancer screening as of September 2021. 
  • In addition, their program used recommended guidelines for determining eligibility and did not require prior authorization or cost sharing.

Prevention

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

State of Tobacco Control

Each year the Lung Association publishes the "State of Tobacco Control" report. The 2021 report grades all 50 states and the federal government on four key tobacco control policies: tobacco control and prevention spending, smokefree air, tobacco taxes, and cessation coverage.

Tobacco Use:

  • The smoking rate in South Dakota is 18% and significantly higher than the national rate of 15%.
  • It ranks 36th among all states, 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 since 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 South Dakota, 60% of radon tests results were at or above the action level recommended by EPA.
  • It ranks 51st 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 2021 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.

Racial & Ethnic Disparities

Black

Black Americans:

  • Lung cancer rates are not available for Black Americans in South Dakota due to too few cases over the time period to allow for accurate analysis.
Latino

Latino Americans:

  • Lung cancer rates are not available for Latino Americans in South Dakota due to too few cases over the time period to allow for accurate analysis.
Asian & Pacific Islander

Asian Americans or Pacific Islanders:

  • Lung cancer rates are not available for Asian Americans or Pacific Islanders in South Dakota due to too few cases over the time period to allow for accurate analysis.
Indigenous Peoples

Indigenous Peoples:

  • The rate of new lung cancer cases is 90 per 100,000 population among Indigenous Peoples (American Indians/Alaska Natives) in South Dakota, significantly higher than the rate of 41 among Indigenous Peoples nationally, and significantly higher than the rate of 57 among whites in South Dakota. 
  • State-level survival rates are not available for Indigenous Peoples at this time. Nationally, the five-year survival rate among Indigenous Peoples is 19%, 11% lower than among white Americans. 
  • 22% of lung cancer cases are diagnosed at an early stage among Indigenous Peoples (American Indians/Alaska Natives) in South Dakota, not significantly different than the rate of 22% among Indigenous Peoples (American Indians/Alaska Natives) nationally, and not significantly different than the rate of 26% among whites in South Dakota. 
  • 14% of Indigenous Peoples (American Indians/Alaska Natives) with lung cancer in South Dakota underwent surgery, not significantly different than the rate of 17% among Indigenous Peoples (American Indians/Alaska Natives) nationally, and not significantly different than the rate of 16% among whites in South Dakota. 
  • 29% of Indigenous Peoples (American Indians/Alaska Natives) with lung cancer in South Dakota did not receive any treatment, not significantly different than the rate of 23% among Indigenous Peoples (American Indians/Alaska Natives) nationally, and significantly higher than the rate of 21% among whites in South Dakota. 

Summary

Despite the early diagnosis rate in South Dakota 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.

South Dakota has improved access to screening by covering it through its fee-for-service Medicaid program. The Lung Association encourages all states to cover lung cancer screening based on recommended guidelines across all fee-for-service and managed care plans without any financial or administrative barriers in their Medicaid programs.

South Dakota falls into the average tier for percent of patients not receiving any 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:

Sign Our Petition

Sign our petition asking Congress to provide the Centers for Disease Control and Prevention (CDC) with robust and sustainable funding.

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 potential new smokers 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.
