A startling new study from the International Agency for Research on Cancer (IARC), which is part of the World Health Organization, says a new study reveals more cancers than previously thought are related to exposure to asbestos fibers. Results of the study were published this summer in the Lancet Oncology journal.

The findings were part of an article published in the July 19 edition of the Guardian, which says medical researchers now believe that the danger of asbestos exposure may have been “seriously underestimated.”

Asbestos disease – particularly mesothelioma – is a looming epidemic in the UK, expected to peak in the middle of the next decade, resulting in about 5,000 deaths each year, according to figures from the Health and Safety Executive (HSE). Many of these deaths will be a result of secondary exposure, in addition to more typical industrial type exposure, the agency says.

The Guardian article says “patterns of premature fatalities” among such professions as electricians, plumbers, garage mechanics, and even teachers and hairdressers” are now being reported.

Additionally, the government’s Industrial Injuries Advisory Council (IIAC) estimates that as many as 90,000 people each year may be developing pleural plaques – an early indicator of asbestos contamination in the chest cavity and lungs. There is a debate currently raging in the UK to determine whether or not people diagnosed with pleural plaques are eligible to sue for compensation for their injury. A 2007 House of Lords judgment barred these claimants, saying pleural plaques “do not alter the structure of the lungs or restrict their expansion.”

However, proponents for the rights of those with pleural plaques to sue point out that this early asbestos disease could develop into more serious diseases including asbestosis, a severe scarring of the lungs, and mesothelioma, a deadly cancer.

According to the Guardian, more than half of all work-related deaths from six major cancers in the UK are related to asbestos. Additionally, studies estimate that as many as 125 million people around the world work in asbestos-contaminated offices and factories, even if asbestos is not actively used in any manufacturing or other activity at that facility.

Now, the IARC study says “sufficient evidence is now available to show that asbestos also causes cancer of the larynx (throat) and of the ovary.”

Canada is one of the few countries that still mines and produces asbestos, which it exports to countries such as India, Indonesia and Pakistan for use in construction material. Quebec, where Canada’s two asbestos mines are located, has one of the highest rates of mesothelioma in the world.

This week, according to a report by the Canadian HR Reporter, the Canadian Labour Congress is calling for a ban on the mining, and a financial support plan for the approximately 700 miners who would be affected by the industry closure.

The call for the ban comes despite delays in making public the results of a scientific study examining the health risks of asbestos. According to CBCNews.ca, “Michel Arsenault, president of the Quebec Federation of Labour, in February convinced his colleagues at the Canadian Labour Congress not to call for a ban on asbestos mining until after the study was completed and made public.”

The study, conducted under the direction of Health Canada, was begun last November by a team of seven scientific and medical experts. According to CBC, the report was completed in March and promised to be released in weeks. Experts who worked on the project are objecting to the delay in releasing the report.

CBC quotes Leslie Staynor, head of the School of Public Health at the University of Illinois, who worked on the study, as saying, “I want to make the record clear that nothing in the report would argue against the sensibility of an asbestos ban in Canada or for that matter anywhere else in the world.”

The CBC report points out that asbestos has been called a “deadly threat” by the International Labour Organization, the World Health Organization, the International Association for Cancer Research and many more health agencies.

According to a study of U.S. Government Death Data, compiled by the EWG Action fund, Alabama ranks 19th in the U.S. for cases of asbestos related disease (asbestosis) and mesothelioma.

• At least 741 people have been killed by asbestos since 1979 in Alabama.

• 10,881 people have sought justice in Alabama.

• At least 75 shipments (3,624 tons) of vermiculite went from Libby, MT to 4 locations in Alabama between 1948 and 1993.

About the Map

The dots on this map represent individuals who have died from two signature asbestos diseases, mesothelioma and asbestosis, as confirmed by death certificate records. To protect the identity of the victims, the dots on the map have been randomly placed within the county where the death was recorded.

The map includes just a small portion of all asbestos-related mortality that occurred during the time period analyzed. It does not include a single lung cancer death caused by asbestos, although national estimates of lung cancer mortality from asbestos range from 5,000 to 10,000 per year during that time.

The data also grossly underestimate mesothelioma mortality, the signature asbestos-caused cancer. This is in part due to under-diagnosis of the disease, but in greater measure because mesothelioma was not tracked by the federal government as a cause of death until 1999. Prior to that, scientists estimated mesothelioma mortality by assuming cancers of certain sites (for example, the pleura) were mesothelioma. This resulted in dramatic underestimates of the true mortality rates. When the government began tracking mesothelioma as a cause of death, mortality more than doubled, from 935 in 1998, to 2343 in 1999.

The map also does not include asbestos mortality from gastrointestinal (GI) cancer. The link between asbestos and GI cancer is contested by industry and its insurance companies, but OSHA and the World Health Organization International Agency for Research on Cancer all have concluded that asbestos does cause some types of GI cancer (OSHA 1994, WHO 1989). The best national estimates are about 1,200 asbestos-caused gastrointestinal cancers per year.

If the data presented above are corrected to include lung and gastrointestinal cancer and more accurate estimates of mesothelioma incidence, nationwide, the total mortality from asbestos from 1979 through 2001 would be about 230,000 people.
