Malignant Mesothelioma
Malignant mesothelioma is a rare form of cancer
in which malignant cells are found in the sac lining the chest
called the
pleura, in the lining of the abdominal cavity called the
peritoneum or in the lining around the heart, called the
pericardium.
In 1960 the first article was written that actually
established mesothelioma as a disease related to the exposure of
asbestos. This article highlighted more than 30 patients in South
Africa who had been diagnosed with mesothelioma. Of these 30
patients some worked in the mines and others did not. But the
important discovery was that someone had finally put the big picture
together and discovered that this disease was showed a
pattern…
exposure to asbestos could eventually result in a malignant
mesothelioma.
It was only two years later that the first case of malignant
mesothelioma was diagnosed in an asbestos worker in Australia. The
medical history of the patient indicated he had worked at an
asbestos mine for two years, beginning fourteen years earlier. The
fourteen year difference between the beginning of asbestos exposure
and the development of malignant mesothelioma is a perfect indicator
of the latency of this cancer.
The news became even more disturbing in 1965. An article
published in the British Journal of Industrial Medicine that year
established that people who lived in the neighborhoods of asbestos
factories and mines, but did not actually work in them, had
contracted mesothelioma. Tragically, in the town of Wittenoom,
asbestos-containing mine waste was used to cover schoolyards and
playgrounds, exposing countless numbers of children.
Despite the well documented proof that the dust associated with
asbestos mining and milling caused asbestos related disease, mining
continued to be an increasingly booming industry. Even with the
knowledge that asbestos mining and milling was causing disease, no
one stepped up to demand that the workers be protected with safer
work conditions. No one intervened and the incidences of
malignant mesothelioma continued to rise. It is simply
inconceivable that the mine and milling conditions continued
unchecked and the workers continued to be exposed to the asbestos
that could ultimately take their lives.
It wasn’t until 1974 in Australia's Bulletin magazine that
the first public warnings of the dangers of asbestos were published
in a cover story called "Is this Killer in Your Home?" But it wasn’t
for another four years, in 1978, that the Australian Government
actually decided to phase out the town of Wittenoom where you will
remember that asbestos-containing mine waste was used to cover
schoolyards and playgrounds, exposing countless numbers of
children. In no time at all, the once booming town of Wittenoom
became a ghost town…a town lost because of the failure of leaders to
act on the knowledge that exposure to asbestos was for many leading
to the development of a cancer called, malignant mesothelioma.
The former residents of the ghost town were gone but who would
help them to fight the vicious disease many were left to face? Just
one year after the Australian Government decided to shut down the
town, the first lawsuits were filed for negligence related to the
town of Wittenoom and the Asbestos Diseases Society was formed to
represent the Wittenoom victims. This group is still in existence
today and provides counseling, support services, economic
assistance, advocacy, fund-raising for medical research, and
community education.
Could it have been prevented? Could the loss of life have been
less? Could a town have been saved? If changes had been made in
the mining and milling industries when the early research began to
show a direct correlation between the exposure to asbestos and the
development of malignant mesothelioma then, yes,
perhaps lives could have been spared and perhaps a town saved. We
must learn from history…and work diligently so that another tragedy
like Wittenoom never occurs again.

Asbestos Exposure
After asbestos fibers are breathed in, they can easily enter and become trapped
in the airways and lung tissue and the body has difficulty removing the fibers. |
