mesothelioma incidence australia
Malignant mesothelioma is a very rare form of cancer and disease in which malignant cancer cells are found in the sac lining the chest, the cladding abdominal cavity
or lining around the heart.
Mesothelioma affects the mesothelial cells of the heart, lungs, abdomen and reproductive organs. Mesothelioma cancer is 20 to 50 years latency period. Mesothelioma main agents that cause this rare cancer of fiber are minerals such as tremolite asbestos,
erionite, and fluoro-Edenite winchite. Any fibers shorter than 7.8 mu and mu wider than 0.04-0.05 are capable of producing mesothelioma. When inhaled the dust particle size, the crystals from entering the body through the perforation of the organ walls. Once the particles
in the organ tissue, they stay there permanently and begin to cause injury in cells of the mesothelium.
The mesothelioma was associated with primary working environment and exposure to asbestos. For the first mesothelioma was mentioned and described in South Africa
In the 1950s, it was already clearly not necessary heavy exposure to asbestos. An epidemic of mesothelioma has also been documented in Europe, North America, Australia and
even in Japan. Nearly 25 years were necessary for the authorities to fully accept and recognize the danger of asbestos and its health risks became a higher priority than its commercial value. The asbestos market collapsed in mid-1980.
In 1975 another erionite was mentioned as a risk factor for Mesothelioma. Government of Turkey made a study that revealed a high incidence of malignant mesothelioma in lung tissues of people in some small towns in the area of Cappadocia in Turkey, region Central Highlands. Erionite is probably the most toxic mineral, an milligram of fibers in the lungs is fatal.
In November 1999, a newspaper in Seattle published a series of articles about the unusually high incidence of asbestos-related diseases, mesothelioma and deaths among people who had lived in Libby, Montana. Analysis of amphibole asbestiform fibers in the Libby area show winchite proportions of about 84 percent, 11 percent richterite, and only 6 percent tremolite asbestos.
Fluoro-Edenite is fiber other than erionite and winchite not yet classified as asbestos, which has an action mesotheliomatogenous demonstrable in humans. This mineral was found in Biancavilla (in eastern Sicily, Italy), where he was senior people died of mesothelioma pleural. The fibers have been detected in material extracted from quarries in the plaster or mortar of the buildings in Biancavilla.
