The Dangers of Asbestos

The industrial revolution popularized asbestos as people sought ways to make buildings and products less susceptible to fire and electrical damage. The fire, chemical, and electrical resistant properties of asbestos had been known since the times of ancient Greece, but it wasn’t until the early 1900s that its use became widespread. Asbestos is a common,… Continue reading The Dangers of Asbestos

Toxic Effects of Asbestos

The toxic effects of asbestos are not due to its chemical make-up, but its structural features: fibers. Chrysotile is 90% of the world’s asbestos production. Amosite appears to be the culprit. 5-10% amphiboles which are rod forms associated with malignant mesothelioma even when chrysotile is present. Chyrsotile breaks down in the body much faster than… Continue reading Toxic Effects of Asbestos

Asbestos Toxicology

There is some understanding of the etioloy, but the basis for mesothelioma formation is unknown. Asbestos is inert in natural rock form. For it to be hazardous, it must be turned into fine flakes of dust that can be inhaled. So there is a risk in mining, milling, and abatement activities with friability. Respirators make… Continue reading Asbestos Toxicology

Cases of Cancer Clusters

A well-known cancer cluster was discovered in the 1960s and continues to be studied today. The use of asbestos, a naturally occurring mineral, was prevalent in factories, shipyards and building products throughout the 1950s and 1960s. Many individuals who were exposed to asbestos on the job developed a disease known as mesothelioma. Many individuals also… Continue reading Cases of Cancer Clusters

Physical Carcinogenesis

Carcinogenesis is defined as the process of cancer growth. Specifically, the term refers to the process by which normal cells in the body mutate into cancer cells. In order for carcinogenesis to occur, damages in healthy cell DNA must occur. For this reason, carcinogenesis is often tied to genetics. However, exposure to certain chemicals and… Continue reading Physical Carcinogenesis

New Polymer Test Improves Lung Cancer Diagnosis, Says Experts

A new technique used for testing for the presence of lung cancer could potentially reduce diagnosis time from six months to four weeks, according to researchers at the National Institute of Standards and Technology (NIST). This dramatic improvement in diagnosis time comes courtesy of a three-dimensional testing technique known as volumetrics. The procedure involves taking… Continue reading New Polymer Test Improves Lung Cancer Diagnosis, Says Experts

British Contractor Fined for Illegal Asbestos Removal

A judge at the Caerphilly Magistrates’ Court fined a building contractor £2,500 (US$3,893) for disregarding regulations governing asbestos remediation. Ron Couch Building Contracts Ltd. of Pontypool paid the fine after pleading guilty to two counts of violating the country’s Control of Asbestos Regulations. The firm was accused of taking on asbestos removal projects without a… Continue reading British Contractor Fined for Illegal Asbestos Removal

Canada Aims to Save Lives With Standardization of Mesothelioma Data

Canada, a leading exporter of asbestos,  has announced a nationwide initiative that is designed to give cancer researchers and health officials improved access to research data.  Known as the National Staging Initiative, the project will serve to enhance the sharing and cooperation of cancer research across all provinces and territories. Specifically, the initiative will focus… Continue reading Canada Aims to Save Lives With Standardization of Mesothelioma Data
