Asbestos, a much used construction material for its heat and fire resistant properties is currently looked at with shame because it does not take main cause for cancer named as mesothelioma. Exposure to asbestos dust dust and fibers has caused cancer in many people in the past century. Asbestos cancer is exclusively caused as a result of exposure to asbestos. It is due to this reason that asbestos is actually banned for usage in construction and mining industry in a variety of countries.
It has been found that asbestos causes mesothelioma cancer and that is an aggressive type of cancer that affects mesothelial cells in the body. These mesothelial cells spread throughout the entire body forming a safety layer for organs and entire body cavities. Asbestos fibers, dust in addition to particles rupture these mesothelial cells which aggravates to cancer. The way asbestos affects mesothelial cells contributing to asbestos cancer is still unidentified, but the researches have uncovered dangers due to asbestos.
Irritation and inflammation of mesothelial cells results in irreversible damage and scarring. This eventually results in asbestos cancer. Asbestos fibers affect normal cell division contributing to cellular changes. Moreover, these fibers encourage growth associated with cancer causing free radicals in the body. These free radicals affect DNA contributing to abnormal cell mutation. Asbestos also causes over production of oncoproteins which usually overrule normal cellular division restrains.
Types Of Mesothelioma
As mesothelial cells are usually spread across all body internal organs, cancer is categorized based on where cancer cells are only. Pleural mesothelioma is the many widespread asbestos cancer affecting pleura layer of the lungs. About 75% of mesothelioma patients endure pleural mesothelioma. Mesothelioma is also found in the abdominal region and it is named as peritoneal mesothelioma. Abdominal cavity and abdominal organs are affected by this kind of asbestos cancer.
Heart is also affected by asbestos particles and it results in pericardial mesothelioma which affects membrane surrounding the heart. A rare form of mesothelioma is found in lining protecting testicles. It is known as as testicular mesothelioma.
Presence of asbestos fibers in the body can affect any organ. Gastrointestinal cancer and colorectal cancer is also found to be caused as a result of asbestos exposure. This cancer is also found in several patients within kidney, esophagus, throat and gallbladder. Teat cancer, prostrate cancer and leukemia will also be caused by asbestos exposure. It is found that asbestos affects ovarian lining contributing to ovarian cancer.
Diagnosis Of Asbestos Cancer
Mesothelioma, commonly called as cancer doesn't show symptoms until in the future stage. The disease has a long latency period and a couple of diagnostic test is conducted to confirm cancer. X rays, CT and MRT scans in addition to biopsy tests are conducted to diagnose tumor.
