What is the term for the inflammation caused by asbestos?
Pneumoconiosis caused by asbestos is called asbestosis. If a person breathes in harmful dust particles, they can be deposited in the lungs. The body’s immune system will send cells to surround the dust particles to try to stop them causing damage. This causes inflammation and can sometimes lead to scar tissue, known as fibrosis.

There is no cure for pneumoconiosis, and there is no specific treatment either. In other words, pneumoconiosis is managed by trying to improve a person's signs and symptoms, limit the damage, and improve their quality of life.
What is pneumoconiosis caused by?
Pneumoconiosis is a group of heterogeneous occupational interstitial lung diseases caused by the inhalation of mineral dust in the lungs, which leads to lung dysfunction.[1] This dust is primarily inorganic particles, such as free silica dust, asbestos fibers, dust from coal mines, and mixed silicate dust.
Why is it so difficult to differentiate pneumoconiosis from other diseases?
It is difficult to differentiate pneumoconiosis from similar diseases because of its long incubation period and vague clinical symptoms. Diagnosis relies on laboratory examinations, such as bronchoalveolar lavage fluid (BALF), to observe the sediment in the alveoli and exclude similar pulmonary diseases.
What is the term for a spectrum of pulmonary diseases caused by inhalation of mineral dust?
Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust, usually as the result of certain occupations. The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis, which can eventually lead to death caused by respiratory and/or heart failure.
What are the pathological characteristics of pneumoconiosis?
The pathological characteristics of the disease are chronic pulmonary inflammation and fibrosis.[2] Inflammation can promote pulmonary fibrosis, and then lead to pneumoconiosis. [3] Pneumoconiosis is prevalent worldwide, and has maintained a relatively high incidence in recent years.

What Is Pneumoconiosis?
- Pneumoconiosis is a lung condition that is caused by inhaling particles of mineral dust, usually while working in a high-risk, mineral-related industry. At first, irritating mineral dust can trigger lung inflammation, which causes areas of the lung to be temporarily damaged. Over time, these areas can progress to form tough, fibrous tissue deposits...
Symptoms
- Pneumoconiosis sometimes does not cause any symptoms. When symptoms develop, they can include: 1. Cough (with or without mucus) 2. Wheezing 3. Shortness of breath, especially during exercise If pneumoconiosis causes severe lung fibrosis, breathing can become extremely difficult. When this happens, the patient's lips and fingernails may have a bluish tinge. In very advanced di…
Diagnosis
- Your doctor will ask about your exposure to mineral dusts, the number of years you were exposed, and whether you used protective clothing and equipment. Your doctor will examine you, paying special attention to your chest. This will be followed by a chest X-ray, which will be compared to a set of standard X-rays published by the International Labor Office for the evaluation of pneumoc…
Prevention
- Pneumoconiosis almost always can be prevented. To reduce your risk, you can: 1. Limit work-related exposure to mineral dusts — Workers who routinely deal with mineral dusts always should use approved measures (protective equipment and clothing) to limit their exposure and keep from bringing mineral dust home on their clothing. If a mask or respirator is worn as a protection agai…
Treatment
- If you have pneumoconiosis and you develop breathing problems, your doctor will advise you to avoid further exposure to the mineral dust. He or she may prescribe one or two medicines that are inhaled to decrease inflammation in your airways and to help keep your bronchial tubes open. If the oxygen level in your blood is below 90%, you may need to breathe additional oxygen at home…
When to Call A Professional
- Call your doctor promptly if you have symptoms of pneumoconiosis and you have worked at a job where there is a high risk of exposure to mineral dust.
Prognosis
- The outlook for this disease depends on the specific type of pneumoconiosis, the length of exposure to mineral dust, the level of exposure and whether the patient is a smoker. In the long term, people with asbestosis and talc pneumoconiosis have an increased risk of lung cancer and malignant mesothelioma (cancer of the membranes lining the lungs and abdominal cavity). The …
