Study Confirms: Any Asbestos Exposure Can Cause Mesothelioma
How to keep yourself safe
A common question among mesothelioma patients, or even people just interested in learning about the cancer, revolves around levels of asbestos exposure.
They ask, “How much asbestos must you be exposed to in order to develop mesothelioma?” or “How often must asbestos exposure occur for you to be in danger?”
The answer is simple: any amount or frequency greater than zero.
No matter if you were exposed to a low quantity or just one instance of exposure, you could be at risk. A BMJ Case Reports abstract published last week reasserts this fact. The study analyzed the case of a pleural mesothelioma patient who had “remote, short-term asbestos exposure.”
How Mesothelioma Develops in Your Body
Exposure to asbestos particles is the only cause of mesothelioma, a rare disease with around 3,300 new cases in the United States each year. Mesothelioma originates most often in the lining between the lung cavity and chest wall. This space is called the pleura, and the disease is known explicitly as pleural mesothelioma.
Mesothelioma can also form in the peritoneum, which is a thin membrane wrapping around the abdominal cavity. This form of the cancer is called peritoneal mesothelioma.
Asbestos can enter the body either through breathing in or swallowing loose fibers. These sharp pieces of dust can then penetrate the cells that comprise these small linings. If the fibers aren’t expelled from the body — and instead irritate the cells — then cellular mutation can occur.
The more often someone is exposed to asbestos — and the more of the mineral they interact with — the more likely these loose fibers enter their body and irritate cells. However, just one instance — or even one piece of fragmented asbestos dust — could turn healthy cells into diseased ones.
Where Asbestos Exposure Occurs
The report concludes with the same sentiment regarding mesothelioma and asbestos exposure levels. The study showed why “the degree of asbestos exposure to induce a malignant mesothelioma may be smaller than has been traditionally thought.”
The most common source of exposure is occupational. Construction, insulation, electrical and automobile mechanic work all involved asbestos parts for decades — up until the very end of the 20th century. Many other trades — such as baking, boiler work and plumbing — also likely involved regular exposure.
However, as the study shows, any instance of exposure could cause mesothelioma. Since it was so widely used — in addition to mining and production facilities — throughout the 20th century, the mineral is just about everywhere. People can be exposed to loose asbestos particles without ever working in an at-risk occupation.
