Asbestos Cancer - Overview

Over the course of the past century, millions of innocent people have been exposed to asbestos, a class of fibrous minerals known to cause a variety of cancers.

Once asbestos is inhaled it can lodge itself within the body's organs causing cells to mutate and become cancerous.

Often referred to as "asbestos cancer," mesothelioma is the most common form of cancer caused by asbestos exposure. Other deadly forms of cancer are also caused by exposure to asbestos, such as lung cancer, gastrointestinal cancer, and colorectal cancer, just to name a few.

For many decades asbestos was considered an acceptable source of insulation, and thousands of materials made from asbestos were widely applied in industrial and domestic settings.

Asbestos was found in countless products on the commercial market, in many factories, homes and public structures, and in a myriad of industries, such as railway production, shipbuilding, and energy production.

For information about at-risk workplaces and products, please see Occupations at Risk for Asbestos Exposure and Products Containing Asbestos.

Of the millions of people who have been exposed to asbestos in the United States alone, thousands have developed life-threatening illnesses, many of which are aggressive cancers. Each year, approximately 10,000 Americans die from diseases caused by exposure to asbestos.

Mesothelioma Cancer

Mesothelioma cancer specifically targets the body's mesothelial cells.

The most common form of cancer caused by asbestos is mesothelioma, a rare cancer that is very rarely cured. The only proven cause of mesothelioma is exposure to asbestos.

An estimated 20 to 30 percent of people diagnosed with mesothelioma have no knowledge of prior exposure to asbestos. But the prior popularity of asbestos as a building material may shed some light on a person's ability to identify the source of their exposure to asbestos.

Mesothelioma typically attacks the thin membranous lining of the lungs, abdomen, or heart, known as the mesothelium. It is estimated that 2,000 to 3,000 new cases of mesothelioma are reported each year. The symptoms of mesothelioma typically arise 20 to 50 years after exposure, which makes it difficult to diagnose the countless cases lying dormant across the country. For more information about mesothelioma, please see Mesothelioma Overview.

Lung Cancer

Aside from mesothelioma, lung cancer is the most common form of cancer associated with asbestos exposure.

Another dangerous cancer caused by asbestos exposure is lung cancer, of which there are two types: small cell lung cancer and non-small cell lung cancer. The latter is the most common type, accounting for nearly 80 percent of known cases. The identification of lung cancer is determined by the appearance of cancer cells under a microscope from a tissue sample.

Symptoms of lung cancer include coughing and chest pain, shortness of breath or difficulty breathing, a change in sputum volume or color, or the presence of blood in sputum. Other symptoms may occur elsewhere in the body, such as weight loss, tiredness, and headaches. As with the development of mesothelioma after exposure to asbestos, lung cancer symptoms appear many years after initial exposure to the hazardous mineral. Anyone who suspects they may have been exposed to asbestos and are experiencing any symptoms of lung cancer should seek the advice of a medical physician.

Other Associated Cancers

Though the aforementioned types of cancer may be those most commonly associated with exposure to asbestos, the presence of asbestos fibers in the body can cause a number of other, very serious and life-threatening cancers, such as gastrointestinal cancer and colorectal cancer. Please see Gastrointestinal Cancer and Colorectal Cancer for information about these diseases. According to the National Cancer Institute, asbestos exposure can also increase one's risk of developing kidney, throat, esophagus, and gallbladder cancer.

Associated Risk Factors

As with exposure to many carcinogens, the risk of developing cancer is influenced by a number of factors relating to exposure. First, the amount of asbestos to which a person is exposed is an important factor. Evidence shows the likelihood of developing serious asbestos-related disease compounds as the number of asbestos fibers in the body increase.

Additionally, the duration of exposure may also play a part in the risk of developing cancer.

The risk of contracting an asbestos-related disease increases if the person experienced extended exposure. In addition, different types of asbestos bear varying degrees of risk, as do personal lifestyles, when determining one's risk of developing cancer.

As with many other illnesses, those who smoke or have a preexisting disease have a higher risk of developing cancers caused by asbestos.For instance, people who have developed non-malignant, pleural lung diseases as result of exposure to asbestos have a greater risk for developing lung cancer.

The Next Step

Those who believe they may have been exposed to asbestos at any time should consult a physician for a medical examination. Cancers caused by asbestos exposure may present symptoms many years or even decades after initial exposure, by which time it may be too late to seek curative treatments. In addition to contacting a medical professional, the advice of an asbestos lawyer should also be sought for those who have been exposed to asbestos.
