• Asbestos is a mineral that has been linked to many diseases, including lung cancer.
  • Mesothelioma is a rare type of fast-growing cancer that is almost always caused by exposure to asbestos.
  • Treatment for lung cancer or mesothelioma may include surgery, radiotherapy and chemotherapy.
Asbestos is a mineral made up of tiny fibres. When disturbed, it forms a dust. The fibres can be breathed into the lungs where they remain for decades. Asbestos used to be a common building material, but now we know that long-term exposure to this mineral can cause illnesses like cancer.

Due to these health risks, asbestos is no longer mined, milled or manufactured in Australia. It is illegal to store, sell, install or re-use any products containing asbestos in Australia, and no asbestos products may be imported. Asbestos products already in place are allowed. However, strict precautions govern the removal and disposal of asbestos and asbestos-containing materials.

High-risk industries and asbestos

Almost everyone has been exposed to asbestos in small degrees, but some people are at greater risk than others.

Long-term exposure to asbestos has occurred in occupations such as:
  • asbestos mining
  • asbestos manufacturing
  • building demolition, if the buildings contain asbestos.

Asbestos and lung cancer

Cigarette smoking causes most lung cancers, but long-term exposure to asbestos is also a cause of lung cancer. People who smoke and have been exposed to asbestos have a very high risk of developing the disease. Each year in Victoria, about 2,657 people are diagnosed with lung cancer.

The two main types of lung cancer are:
  • small cell lung carcinoma –which has a strong relationship to cigarette smoking
  • non-small cell lung carcinoma –which has three main forms.
The three forms of non-small cell lung carcinoma are:
  • squamous cell carcinoma – which starts in the large air passages called bronchi
  • large cell carcinoma – similar to squamous cell carcinoma
  • adenocarcinoma – the most common form of lung cancer. Incidence is increasing and may be related to changing patterns of smoking. This starts in glands found in the lining of the airways.

Asbestos and mesothelioma

Mesothelioma is a rare but fast-spreading cancer that is almost always caused by exposure to asbestos. It can take over 20 years after exposure for any disease to become evident (and even up to and over 50 years). Australia has one of the highest rates of mesothelioma in the world. This is due to the high rate of asbestos use and mining over many years.

In Victoria, there are about 131 cases diagnosed each year. Experts believe the number of people diagnosed with asbestos-related diseases will not peak until 2020.

Mesothelioma usually starts in the membrane that wraps around the lungs, called the pleura. The cancer cells cause a build-up of fluid between the pleura and the lungs, which in turn causes pressure on the lungs. The symptoms are shortness of breath and a dry, painful cough.

The cancer may eventually grow into the chest wall. Sometimes, the cancer can develop in the lining of the abdomen (peritoneum), the membranes of the heart or reproductive organs.

Diagnosing lung cancer or mesothelioma

There are a number of tests to check for lung cancer or mesothelioma, including:
  • x-rays – either standard x-rays or CT scans, which give a three-dimensional picture of your chest
  • sputum cytology test – an examination of your sputum (phlegm), since cancer cells are sometimes coughed up
  • biopsy – a small sample of lung cells removed with special instruments, under local or general anaesthetic
  • other tests – such as bone, liver or brain scans and blood tests, to see if the cancer cells have spread to other parts of your body.

Treatment of lung cancer and mesothelioma

As lung cancer and mesothelioma are often diagnosed in their later stages, it can be difficult to treat them. However, with more and more research into these types of cancer, treatments are improving.

Treatment may include:
  • surgery – to remove the tumours
  • radiotherapy – the use of x-rays to kill cancer cells
  • chemotherapy – anti-cancer medication that kills cancer cells.

Other illnesses linked to asbestos

As well as cancer, some asbestos-linked non-cancerous conditions include:
  • Asbestosis – scar tissue forms inside the lungs and makes breathing difficult.
  • Pleural plaque – asbestos fibres can cause thickened patches of scar tissue on the pleura, or lung lining.
These are non-cancerous conditions.

Compensation claims for cancer linked to asbestos

A person who develops lung disease after exposure to asbestos may be entitled to seek compensation. Contact a solicitor for information.
