Asbestos Related Illness
What causes it?
Asbestos is a naturally occurring fibrous
mineral often found in insulation materials
around pipes and tanks, in tiles and other
building materials. It was used extensively
in the 1970s because of its strength and
heat resistance.
White, blue and brown asbestos are all
potentially dangerous and have all been
banned in the UK.
This is become if asbestos is damaged, the
fine fibres become airborne and can be
inhaled. When these fibres penetrate the
lung tissue, they trigger an inflammatory
reaction. The body recognises there's a
problem and sends defensive white blood
cells to engulf and attack the fibres.
The fibres usually resist and destroy
these blood cells, promoting further
inflammation and irreversible scarring of
the lungs, called fibrosis.
There's no known safe level of asbestos
exposure. However, it's thought the higher
the levels of asbestos and the longer the
time someone is exposed to it, the greater
their risk of developing problems.
Who's affected?
Anyone who's exposed to asbestos may
develop an asbestos-related illness.
Particularly at risk are those involved in
the building and demolition industry, the
manufacture of asbestos products and
asbestos spraying.
Asbestos fibres are also carried on
clothing, so the families of those working
with asbestos and those involved in the
laundering of an asbestos worker's clothing
may be at risk.
Asbestos is now used less and working
practices have been developed to protect
people from asbestos exposure.
What are the symptoms?
The effects of asbestosis don't tend to
appear for many years, often between 25 and
40 years later.
The main symptom is shortness of breath,
initially on exertion but later even at
rest. Others include tiredness, a cough,
chest tightness and chest pain.
Asbestos can cause thickening of the
pleura, the membrane that lines the outside
of the lung. Often this will only be noted
when an x-ray is performed for another
reason. If the thickening is severe and
widespread, it restricts lung function
causing shortness of breath.
Mesothelioma is a rare form of cancer
that's only caused by exposure to asbestos.
It can occur in the pleura, where it may
cause shortness of breath or chest pain, or
the peritoneum (the lining of the abdominal
wall), where it may cause intestinal
obstruction.
How is it diagnosed?
A history of exposure to asbestos, the
pattern of symptoms experienced, a chest
x-ray and lung function tests are usually
all that's needed to make the diagnosis of
asbestosis.
People who've been exposed are often
advised to have regular check-ups because it
may take years before lung damage becomes
apparent.
What's the treatment?
Although there's no cure for asbestosis,
it's important to prevent the symptoms
becoming worse by avoiding further exposure
to asbestos.
Medication can be prescribed to relieve
symptoms and improve breathing. Some people
with severe problems are given oxygen.
