Symptoms Of Asbestos Related Diseases

We are all exposed to low levels of asbestos in the air we breathe. These levels range from 0.00001 to 0.0001 fibers per milliliter of air and generally are highest in cities and industrial areas.

It is known that breathing asbestos can increase the risk of cancer in people. There are two types of cancer caused by exposure to asbestos: lung cancer and mesothelioma. Mesothelioma is a cancer of the thin lining surrounding the lung (pleural membrane) or abdominal cavity (the peritoneum). Cancer from asbestos does not develop immediately, but shows up after a number of years. Studies of workers also suggest that breathing asbestos can increase chances of getting cancer in other parts of the body (stomach, intestines, esophagus, pancreas, and kidneys), but this is less certain. Early identification and treatment of any cancer can increase an individual’s quality of life and survival.

People working in industries that make or use asbestos products or who are involved in asbestos mining may be exposed to high levels of asbestos. People living near these industries may also be exposed to high levels of asbestos in air.

Asbestos fibers may be released into the air by the disturbance of asbestos-containing material during product use, demolition work, building or home maintenance, repair, and remodeling. In general, exposure may occur only when the asbestos-containing material is disturbed in some way to release particles and fibers into the air.

Symptoms

Asbestos mainly affects the lungs and the membrane that surrounds the lungs. Breathing high levels of asbestos fibers for a long time may result in scar-like tissue in the lungs and in the pleural membrane (lining) that surrounds the lung. This disease is called asbestosis and is usually found in workers exposed to asbestos, but not in the general public. People with asbestosis have difficulty breathing, often a cough, and in severe cases heart enlargement. Asbestosis is a serious disease and can eventually lead to disability and death.

Breathing lower levels of asbestos may result in changes called plaques in the pleural membranes. Pleural plaques can occur in workers and sometimes in people living in areas with high environmental levels of asbestos. Effects on breathing from pleural plaques alone are not usually serious, but higher exposure can lead to a thickening of the pleural membrane that may restrict breathing.

Low levels of asbestos fibers can be measured in urine, feces, mucus, or lung washings of the general public. Higher than average levels of asbestos fibers in tissue can confirm exposure but not determine whether you will experience any health effects.

A thorough history, physical exam, and diagnostic tests are needed to evaluate asbestos-related disease. Chest x-rays are the best screening tool to identify lung changes resulting from asbestos exposure. Lung function tests and CAT scans also assist in the diagnosis of asbestos-related disease.

Mesothelioma Is Asbestos Cancer

Mesothelioma is cancer that affects the mesothelium which is the lining or membrane that protects and covers most of the internal organs in the body cavity. The first layer encircles the organ and the second layer forms a sac for protection. There is a lubricating fluid present between the layers to facilitate movement. The mesothelium is called pericardium when it covers the heart, pleura when covering the lungs and peritoneum when covering the abdominal organs.

In mesothelioma there is uncontrolled cell division which leads to the extra cell masses invading the nearby tissues and organs and causing damage. Mostly it is observed that mesothelioma begins in the pleura or the peritoneum. The cancer then metastasizes to other parts of the body.

Mesothelioma occurs mostly due to exposure to asbestos. This is considered to be the major risk factor. 70% to 80% of sufferers have a history of exposure to asbestos. There are exceptions to this and cases have been reported where asbestos exposure was found not to exist. The condition is more common in men as compared to women. It has also been found that risk increases with age.

Mesothelioma is a very rare. Mostly said to be associated with workplace exposure to asbestos. Asbestos is a collection of minerals that can be made to exist as strong masses of sheets or flexible fibers. It is widely used in industrial products like cement, roofs, flooring products, textiles, brake linings and insulation. Tiny particles of asbestos float in the air and can be inhaled or swallowed by the people exposed to it like the workers in manufacturing companies etc.

Continuous exposure over a period can lead to asbestosis. Exposure to asbestosis increases the risk of developing mesothelioma and other types of cancer like that of kidney and larynx. There are acceptable levels of asbestos exposure that have been brought into effect in workplaces using the mineral. Another very interesting aspect of mesothelioma is that family members of people exposed asbestos in their work place show an increased incidence of this cancer as compared to others. This has been attributed to the fact that the remnants of asbestos particles adhering to the clothes, hair etc when brought home can expose the family members to it.

The cancer takes around thirty to forty years to surface. The initial symptoms include shortness of breath, and pain in the chest if it is the pleura that are affected. If the cancer is in the peritoneum then there is weight loss, abdominal swelling and pain, fluid accumulation in the abdomen, bowel obstruction. Fever, anemia and blood clotting irregularities have also been observed. In severe cases there is swelling of the neck and face, trouble swallowing and severe pain.

Diagnosis of mesothelioma is very difficult since there are no specific symptoms. A medical history review would be very valuable since asbestos exposure needs to be determined. X rays of chest, abdomen, lung function tests, scans, MRI are the usual tools that help in confirming the diagnosis. Biopsy is done for the final confirmation and treatment includes chemotherapy and radiations.

Facts About Asbestos Causing Mesothelioma

Mesothelioma Cancer Killed Steve McQueen

Exposure to Asbestos is the most common cause of mesothelioma. Almost all cases of mesothelioma are caused by asbestos exposure. Asbestos is a natural mineral which is mined from rock found in many countries around the world. It is made up of tiny fibres as strong as steel, woven like cotton and highly resistant to heat, chemicals and electricity.

The first definite link between mesothelioma and asbestos was made in the 1960s. At that time, asbestos was very widely used in the manufacture of insulation materials, such as insulation board and building materials, including cement.

When asbestos is damaged or disturbed, it releases tiny fibres, almost invisible to the naked eye, which, when airborne can breathed in, and cannot be exhaled or coughed out. Once the fibres are in the lungs, the body’s defence mechanism tries to break them down and remove them, which leads to inflammation in the lung’s tissue.

Asbestos fibres can also penetrate through the lung tissue to settle in the pleura (the membrane around the lung). Over many years they can cause asbestosis, mesothelioma or other lung diseases to develop. Asbestos fibres can also be swallowed, and some of the fibres become lodged in the digestive system. They will then move into the membrane that lines the abdomen (the peritoneum), where they cause inflammation.

Those individuals most likely to have been exposed to asbestos will include: construction workers, boilermakers, construction workers, demolition workers, electricians, plumbers, shipbuilders etc. Family members of those who worked with asbestos and unwittingly brought asbestos dust home on their clothes, will also be at risk and have also been known to developed mesothelioma.

There are three types of asbestos and these are: blue, brown and white. The blue and brown asbestos types are most commonly linked with mesothelioma, and are now very rarely used. However, although originally, white asbestos was thought not to be dangerous, recent studies have shown that it is also harmful.

Although by 1999 the importation and use of all asbestos was banned, and because mesothelioma develops so slowly, it is estimated that by the year 2015, approximately 3000 people will have been diagnosed with mesothelioma each year. After this time, the number of people who develop mesothelioma will begin to fall annually.

Mesothelioma does not typically develop for many years after the initial exposure to asbestos. Although it can take anything from 10 to 60 years, the average time is around 30 to 40 years after asbestos exposure.

Occasionally, mesothelioma will be diagnosed in people who have never had any history of asbestos exposure. Other causes of the disease are to date not fully understood, but in rare cases mesothelioma has been linked to radiation exposure.

Research has found no evidence that smoking increases an individual’s risk of developing mesothelioma. It is understood that exposure to other building materials, for example fibreglass also will not increase the risk. Mesothelioma is not a contagious disease and therefore cannot be passed on to other individuals. Family members are only at risk when in contact with asbestos particles.
