Mesothelioma & Lung Cancer Due to Asbestos Exposure in Hawaii (HI)

Mesothelioma and Lung Cancer Prevalence in Hawaii

Mesothelioma and lung cancer are two deadly diseases commonly caused by prolonged exposure to asbestos. Microscopic asbestos fibers can become lodged in the thin tissues lining internal organs, leading to severe and often fatal illnesses.

From 2017 to 2021, Hawaii recorded an age-adjusted mesothelioma rate of 0.3 per 100,000 people, with 34 new cases reported.

Almost all buildings in Hawaii constructed before 1980 contain traces of asbestos, creating ongoing health risks for both residents and visitors.

Lung cancer also poses a significant health concern in the state. In 2023, an estimated 930 new lung and bronchus cancer cases were reported in Hawaii, resulting in approximately 480 deaths.

Between 2017 and 2021, the age-adjusted lung cancer rate in Hawaii was 39.8 per 100,000 people, with 4,045 new cases diagnosed during that period. As of 2024, the lung cancer incidence rate stands at 40.0, which is lower than the national average of 53.6. Hawaii ranks sixth in the United States for lung cancer incidence, with new case rates improving by 17 percent over the past five years.

Contributing Factors

Unlike many states, Hawaii does not have naturally occurring asbestos deposits. However, asbestos exposure has historically resulted from occupational activities, imported materials, and older buildings constructed before regulatory changes.

Shipyards, particularly the Pearl Harbor Naval Base, were major sources of asbestos exposure. Asbestos was widely used in shipbuilding materials such as insulation, piping, and adhesives. Military facilities, power plants, and manufacturing sites also contributed to exposure risks.

The agricultural sector posed additional hazards, as asbestos-containing materials were commonly found in farming equipment. In 2023, wildfires on Maui worsened the situation by releasing asbestos fibers and other toxic substances, including arsenic and lead, into the air.

Public buildings such as schools, government offices, and residential homes—especially those built before 1980—continue to present asbestos exposure risks. Occupational exposure remains a critical factor in protecting Hawaii's workforce and residents.

Prolonged asbestos exposure has also been linked to increased lung cancer rates, particularly among individuals who smoke.
