How Silicosis Develops
Cutting or polishing stone releases tiny silica particles into the air. These particles are so small that no one can see or feel them going in. The CDC explains that this dust causes inflammation and scarring in the lungs. Breathing gets harder. The damage cannot heal, and it often keeps getting worse even after the exposure stops.

Causes of Silicosis
Silicosis is one of the oldest known workplace illnesses. Physicians described breathing problems in miners more than two thousand years ago, and the disease got its modern name in 1870, when Italian pathologist Achille Visconti coined the term, according to a history of silicosis published in Frontiers in Public Health. But silicosis never fully disappeared, and the CDC has described it as an emerging public health threat again among young workers cutting artificial stone.
Artificial stone can consist of more than 90% silica, per the CDC, and the popularity of these countertops are driving today’s surge in cases. The dust from artificial stone is also finer and mixed with resin. Because of the high concentration of silica and the fine dust artificial stone produces, stone workers are developing severe silicosis far faster than earlier generations of stone and construction workers did.
Common Symptoms of Silicosis
Silicosis often starts quietly. Many people mistake early symptoms for aging, allergies or just being tired from a long shift. Here are some symptoms to watch for, according to the American Lung Association:
- Shortness of breath
- A persistent cough
- Chest tightness
- Fatigue and unexplained weight loss
- Breathing difficulty that keeps getting worse
How is Silicosis Diagnosed
Diagnosing silicosis requires knowing your work history and your symptoms. Because many doctors just diagnose based on symptoms alone, silicosis is often misdiagnosed as pneumonia or tuberculosis. A chest X-ray or CT scan and a lung-function test may also be performed, according to the American Lung Association. In cases where the imaging isn’t clear enough on its own, a lung biopsy may confirm the diagnosis.
