Mesothelioma & Lung Cancer Due to Asbestos Exposure in Idaho
Mesothelioma and Lung Cancer Prevalence in Idaho
Sustained asbestos exposure is a leading cause of mesothelioma, a severe cancer that develops when asbestos fibers become embedded in the thin lining of internal organs and eventually form tumors. From 2017 to 2021, the age-adjusted mesothelioma rate in Idaho was 1.0 per 100,000 people, with 21 new cases reported. Major sources of asbestos exposure in the state include the Rocky Mountains, mining operations, and older buildings.
Lung cancer is another serious health concern associated with asbestos exposure. In 2023, an estimated 1,080 new cases of lung and bronchus cancer were reported in Idaho, with approximately 580 deaths.
Between 2017 and 2021, Idaho reported an age-adjusted lung cancer rate of 41.0 per 100,000 people, with 979 new cases during that period. The state's new lung cancer rate of 45.2 is lower than the national average of 53.6. Idaho ranks 10th in the United States for lung cancer incidence, and the rate of new cases has improved by 18% over the past five years.
Asbestos exposure remains a preventable but persistent health risk in Idaho due to natural deposits, aging infrastructure, and legacy industrial practices.
Contributing Factors
The Rocky Mountains in Idaho contain natural asbestos deposits. Notable locations include the Kamiah deposit, Adams County, and Clearwater County. Workers in insulation and construction have historically faced significant exposure risks, leading to cases of mesothelioma and lung cancer.
Older school buildings and aging infrastructure across the state have also contributed to asbestos-related health risks. Additional sites with asbestos deposits include the Teakean deposit, Olson, the Blacktail asbestos prospect, and several unnamed locations in Adams County. Numerous chemical plants and power plants in Idaho have also been linked to asbestos exposure.
In addition to mesothelioma, inhaling asbestos fibers can cause lung cancer. Smoking significantly increases the risk of developing this often-fatal disease when combined with asbestos exposure.
