Do you know about asbestos? Asbestos is a common material, both in the industry and our life. No one denied its benefits, but the other side is ominous, asbestos increases the risk of cancer for humans. If you do not know about asbestos’s harm, I will tell you now.
Firstly, there are over 3000 types of asbestos fiber products manufactured and used in different industries such as construction, car manufacturing, hair dryers, roofing, paint, … But we call asbestos is a hidden killer. When you exposed to asbestos or products containing asbestos, especially asbestos fibers in the air, they will enter your body through the mouth. They will be trapped in the lungs for a long time. By the time, these fibers can accumulate and cause the scar and inflammation, affect respiration and decline our health.
One of the diseases relating to asbestos is asbestosis.
This is a phenomenon of diffuse fibrosis in the lung tissue and usually occurs after 5 to 20 years of exposure to asbestos. The people who work in drilling, demolition, weaving … are at risk to getting this disease. The disease usually manifests by major symptoms: angina and shortness of breath, dry cough at first, cough with expectoration, cough with blood, thin body. Finally, the patient will be exhausted and dead.
Asbestos is perhaps best known for its role in causing mesothelioma, a rare and deadly cancer that can develop in linings of the lungs, abdomen, or heart. Although pleurisy is not a precursor to cancer, we still find evidence shows that people have pleurisy because of asbestos also have a high risk of developing lung cancer. And because of the long incubation, many people ignored their symptoms. Therefore, when they discovered that they had cancer, it is difficult to cure. X-ray of the lung cannot detect asbestos – except when it causes asbestosis or cancer. During the incubation, the doctor just identifies the disease with symptoms. But these symptoms are easily confused with other lung diseases if the doctor does not care about the patient’s occupational history. So, when the people have lung cancer, they do not know about it.
When asbestos is in the form of a combination with other materials, it is less toxic. But when it is in the form of fibers or into the air, asbestos is extremely toxic. Asbestos should be banned in the industry to prevent the harmful effects of this poison.
