Asbestos Exposure Sign
The most common signs of exposure to asbestos include
shortness of breath, coughing and chest pain. Pleural plaque is a sign that a
person has sufficient exposure to risk other diseases. They may develop before
mesothelioma or lung cancer.
The first signs of asbestos exposure are symptoms of a
related disease. There are no signs of asbestos exposure that a person can
identify before the disease develops.
Signs of asbestos exposure usually involve the lungs. That's
because asbestos mainly causes lung disease. Asbestos also causes disease in
other parts of the body. Signs of the disease mainly affect the throat, stomach
and large intestine.
In some cases, routine X-rays or CT scans can identify
pleural plaques. This indicates that adequate exposure occurs to cause other
asbestos related diseases. But pleural plaque is not a sign that anyone can be
aware of because it rarely causes symptoms. Plaques begin to develop 10 to 30
years after exposure.
Signs of exposure to asbestos that affect the lungs
Hard to breathe
Dry cough or wheezing
Sounds crackle while breathing
Chest pain or tightness
Respiratory complications
Pleural effusion (accumulation of fluid in the space
surrounding the lungs)
Pleural plaques
Pleural thickening
Asbestosis
Signs of Asbestos Exposure Affecting Other Body Parts
Abdominal swelling and distension
Abdominal or pelvic pain
Intestinal obstruction
Hernia
Weight loss
Loss of appetite
Hoarseness
Difficulty swallowing
Finger beaten
Disease Caused by Asbestos Exposure
Exposure to asbestos causes cancer and not cancer. The
International Agency for Research on Cancer (IARC) has confirmed that some
cancers are directly caused by asbestos exposure.
Cancer Caused by Asbestos Exposure
Mesothelioma
Lung cancer
Laryngeal cancer
Ovarian cancer
Non-Cancer Diseases and Conditions Caused by Asbestos
Exposure
Asbestosis
Pleural plaques
Pleural thickening
Benign pleural effusion
Pleurisy
Atelectasis
The IARC also found an increase in the risk of other cancers
but has not proven a direct causal relationship. These include gastric cancer,
pharyngeal cancer and colorectal cancer.

Job exposure is the cause of No. 1 asbestos related disease.
Secondary exposure can also cause all of these conditions.
Screening for Asbestos Related Diseases
Asbestos-related diseases rarely produce tangible symptoms
or abnormalities that can be measured in the early stages of development.
Screening for these conditions before difficult symptoms occur and is often
ineffective.
However, if you have a history of severe asbestos exposure,
screening for mesothelioma and other asbestos-related diseases can save your
life. There is no single screening that can detect mesothelioma convincingly,
but a combination of tests can help doctors find potential problems before they
start causing symptoms.
Tell your doctor if you have a history of exposure to
asbestos and request a recommended examination.
Screening Procedure for Asbestos Related Diseases
Chest X-ray
Low-dose CT scan
Spirometry
Bronchoscopy
Bronchoalveolar rinse
Lung function tests
The American Academy of Family Physicians recommends chest
X-ray and lung function every three to five years for patients with asbestos
that are not cancerous. These tests may catch cancer changes in the chest, but
are not fully reliable.
Researchers are developing blood tests for mesothelioma.
Others are developing tests for biomarkers of asbestos exposure. These tests
are not accurate enough to detect signs of asbestos exposure or mesothelioma.
Transvaginal ultrasonography and blood tests for the CA-125
protein can be used as a screening tool for ovarian cancer.
Risk of Developing Asbestos Related Diseases
About 20 percent of people who work with asbestos develop
related diseases.
6 to 10 percent develop mesothelioma
20 to 25 percent suffer from lung cancer
50 percent develop asbestosis
Many factors are involved in the risk of developing
asbestos-related diseases. How long is someone exposed to playing a major role.
Likewise the concentration of asbestos fibers they breathe.
Most sick people work very hard with asbestos for most of
their careers.
All types of asbestos cause this disease. Some fibers appear
to be more carcinogenic, such as crocidolite (blue asbestos).
Genetics and lifestyle choices, such as smoking or using
powder, are risk factors for some of these conditions.
The combination of smoking and exposure to asbestos
significantly increases the risk of lung cancer but not mesothelioma. Smoking
can worsen the development of asbestosis.
Sometimes, a non-cancerous condition develops before asbestos
cancer. They are not a reliable sign that cancer will develop, but they show a
high level of exposure associated with asbestos cancer.
Significant Significance of Pleural Plaques
Pleural plaques are the most common sign of significant
asbestos exposure. They may develop before or with other asbestos diseases. Not
everyone with plaque will suffer from other related diseases.

A 2013
French study published in the Journal of the National Cancer Institute studied
pleural plaque and the risk of mesothelioma. It tracks more than 5,000 asbestos
workers and reports the following observations:
Pleural
plaques were found in 20.4 percent of workers.
About 7.4
percent of workers with one to nine years of asbestos exposure develop pleural
plaques.
More than
50 percent of workers with 40 years or more experience developing plaque.
Workers
with pleural plaques are approximately six to nine times more likely to develop
mesothelioma.
Asbestosis
Asbestosis
is a non-cancerous progressive lung disease that causes severe pulmonary
dysfunction. It doesn't turn into cancer. The diagnosis of asbestosis shows
that a person has sufficient exposure to also be at risk of developing
asbestos-related cancers, especially lung cancer.
A 2013
study published in the American Journal of Respiratory and Critical Care
Medicine studied asbestosis and lung cancer among asbestos insulators. It was
found that people with asbestosis were 7.4 times more likely to develop lung
cancer.
It is less
common for asbestosis patients to develop mesothelioma, but that is possible. A
2017 study published in the journal Safety and Health at Work found no clear
trend between the incidence of asbestosis and mesothelioma.
The Agency
for Toxic Substances and Disease Registration reports that many asbestosis
patients die from other causes. About 9 percent died of mesothelioma and 38
percent died of lung cancer.
Pleural
thickening
Pleural
thickening is a non-cancerous condition associated with severe asbestos
exposure. This does not risk becoming cancerous, but may develop before some
cases of mesothelioma.
Interestingly,
a 1988 study of Australian crocidolite miners found an increased risk of
mesothelioma peritoneum - not pleural mesothelioma - among those who had
pleural thickening.
Common
Questions About Asbestos Exposure
How Much
Safe Asbestos Exposure?
According
to the World Health Organization (WHO), there is no safe level of asbestos
exposure. The level of excess cancer is found in all concentrations of asbestos
fibers. This means that there is no evidence for safe levels of asbestos
exposure.
Can
One-Time Exposures to Asbestos be Dangerous?
It is
possible to get sick because of minimal, but rare exposure to asbestos. There
is a dose-response relationship between asbestos and the disease it causes.
That means the risk of illness increases with increasing exposure.
The
duration of fiber exposure and concentration impacts risk. One-time exposure to
high concentrations of fiber has the potential to cause health effects.
Exposure to asbestos dust in the short term tends to cause health effects
compared to long-term exposure.
What To Do
If You Have Been Affected By Asbestos?
There are
proactive steps you can take if you feel exposed to asbestos.
Tell all
your doctors about your exposure
Get a
cancer examination recommended by your doctor
Monitor
your health for symptoms of asbestos-related diseases
Check the
symptoms quickly and explain your asbestos exposure history
Don't
smoke, and start a termination program if you do it
Lead a
healthy lifestyle by eating well, exercising frequently, and getting enough
sleep
Get flu
vaccine and pneumonia
