What is asbestosis? Asbestosis is a chronic lung disease caused by inhaling asbestos fibers. These tiny, needle-like fibers can become airborne and, when inhaled, lodge in lung tissues, causing inflammation and scarring. This scarring makes it difficult for lungs to expand and contract, leading to breathing problems. Symptoms often take decades to appear, making early detection challenging. Common signs include shortness of breath, persistent cough, and chest pain. Asbestosis primarily affects workers in industries like construction, mining, and manufacturing, where asbestos was widely used. Despite its dangers, asbestos is still used in some countries, posing ongoing health risks.

Mesothelioma and Lung Cancer Statistics
The numbers paint a grim picture of asbestos-related diseases.
-
Mesothelioma Statistics: From 1999 to 2015, 45,221 malignant mesothelioma deaths were reported in the U.S. Insulation workers and plumbers had the highest mortality rates.
-
Lung Cancer Link: Asbestos exposure is responsible for 55% to 85% of lung cancer cases, making it a significant occupational health risk.
Asbestosis Statistics and Disease Progression
Asbestosis remains a serious health issue, with cases increasing over time.
-
Asbestosis Statistics: Asbestosis causes about 3,400 deaths globally each year. Cases increased by 116.6% between 1990 and 2017.
-
Disease Progression: Asbestosis worsens over time. Longer exposure increases the chance of developing the disease, and inhaling longer fibers is more likely to cause it.
Complications and Cancer Risks
Asbestosis can lead to severe complications and increase cancer risks.
-
