Mesothelioma Asbestos Lung Cancer

People with a history of asbestos exposure are about seven times more likely to die from lung cancer than those who are unexposed to asbestos. Asbestos exposure is associated with all types of lung cancer, and with a rare type of cancer called malignant mesothelioma, which affects the tissue lining the lungs called the pleura. The time between exposure and development of cancer ranges from 15 to 30 years. This gap between exposure and disease may delay diagnosis until the lung cancer is advanced and less amenable to treatment. If someone with asbestos exposure also smokes, the risk of getting lung cancer increases substantially.

Until the mid-20th century, asbestos was widely used in construction and to manufacture insulation and fire retardant materials. As knowledge of the health risks associated with asbestos fiber inhalation or ingestion increased, asbestos became less commonly used. While asbestos is still present in many public buildings and in older homes, it is generally thought to be less harmful to leave it in place than to remove it, as doing so may release asbestos fibers into the air. Some industries continued to use asbestos after its risks became known, and are facing lawsuits from former employees.

The symptoms of asbestos-related lung cancer are similar to those of lung cancer in general. These include breathlessness, wheezing, chest pain, coughing up of blood, a new cough or a persistent cough, or hoarseness. A diagnosis is usually made using a combination of physical examination, x-rays, CT scans, lung tissue biopsies, and lung function tests. Recent research suggests that levels of a blood protein, osteopontin, rise in people with malignant mesothelioma. Treatment depends on the type of lung cancer and on the stage or extent of spread when it is diagnosed; overall five-year survival rates are below 20 percent.
