A plaque caused by asbestos exposure on the diaphragmatic pleura: Specialty: Pulmonology: Symptoms: Shortness of breath, cough, wheezing, chest pain [1] Complications: Lung cancer, mesothelioma, pleural fibrosis, pulmonary heart disease [1] [2] Usual onset ~10-40 years after long-term exposure [3] Causes: Asbestos [4] Diagnostic method
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
Pericardial mesothelioma may not be associated with asbestos exposure. [11] Asbestos was known in antiquity, but it was not mined and widely used commercially until the late 19th century. Its use greatly increased during World War II. Since the early 1940s, millions of American workers have been exposed to asbestos dust.
Exposure to asbestos in the form of fibers is always considered dangerous. Working with, or exposure to, material that is friable, or materials or works that could cause release of loose asbestos fibers, is considered high risk. However, in general, people who become ill from inhaling asbestos have been regularly exposed in a job where they ...
Asbestos can cause lung cancer that is identical to lung cancer from other causes. Exposure to asbestos is associated with all major histological types of lung carcinoma (adenocarcinoma, squamous cell carcinoma, large-cell carcinoma and small-cell carcinoma). The latency period between exposure and development of lung cancer is 20 to 30 years.
While these symptoms may indicate cancer, they can also have other causes. [1] Over 100 types of cancers affect humans. [7] Tobacco use is the cause of about 22% of cancer deaths. [2] Another 10% are due to obesity, poor diet, lack of physical activity or excessive alcohol consumption.
Ionizing radiation may be used to treat other cancers, but this may, in some cases, induce a second form of cancer. [74] Radiation can cause cancer in most parts of the body, in all animals, and at any age, although radiation-induced solid tumors usually take 10–15 years, and can take up to 40 years, to become clinically manifest, and ...
Asbestos can be flocked above false ceilings, inside technical ducts, and in many other small spaces where firefighters would have difficulty gaining access. Although asbestos is primarily associated with older buildings in many parts of the world, as asbestos bans have been in place in various countries since 1972, [ 3 ] 2 million tons of ...
