The Link Between Asbestos Exposure and Smoking

It is common knowledge that smoking is hazardous to one’s health. Additionally, many people know that exposure to asbestos is very dangerous and can lead to the development of the disease mesothelioma. What many people do not know, however, is that when smoking and asbestos exposure are combined, both of the harmful elements work together to create a much higher risk for the development of mesothelioma, or other types of cancers.

Cigarettes have many harmful chemicals that break down the lungs and can be leading causes in cancer. Asbestos exposure also exposes the lung to harmful chemicals that weaken your body’s defenses against cancers and other lung problems. Studies have found that cigarette smokers have a four to eleven times greater chance of getting lung cancer than non-smokers. If a person is a heavy smoker, than the number goes up to twenty-seven times as likely. Adding a heavy smoker to asbestos exposure sends the probabilities for lung cancer skyrocketing. In fact, heavy smokers with a history of asbestos exposure have a 50 to 90 times greater chance of having lung cancer. Needless to say, heavy smoking and large amounts of asbestos exposure will almost certainly lead to lung cancer.

Smoking causes chronic obstructive pulmonary disease (COPD). People who smoke and have been exposed to asbestos have higher occurrences of COPD than people who have not been exposed to asbestos. Some of the terrible effects of COPD are the inflammation and eventual destruction of small airways in the lung tissue. Once these tissues have been destroys, some people can be completely debilitated.

Studies have shown that people who quit smoking, but still had asbestos exposure are less likely to have lung cancer than those people who continue to smoke. Some say that COPD can be reversed the longer time is spent without smoking. Additionally, people who are able to quit smoking often feel healthier over time and significantly increase their life expectancy. Even though any amount of smoking or asbestos exposure can lead to lung cancer, the sooner one quits, the better off he or she will be.

Asbestos exposure is very harmful for anyone. However if you know that you have been exposed to asbestos, and continue to smoke, you are playing with fate. The sooner someone stops smoking, the sooner his or her lungs can begin to heal. Mesothelioma and other cancers are very serious diseases that often end in death. In order to stay alive for loved ones, smokers should quit immediately.


Who is at Risk for Mesothelioma?

Mesothelioma, the deadly disease which has topped news headlines for the last decade, is contracted through exposure to airborne fibers of asbestos.  Sadly, the under-regulation of asbestos usage in years past, and arguably still today, exposed millions to airborne fibers and as a result thousands contracted the disease. 

It can be safely said that almost everyone in the world has been exposed to asbestos in varying degrees. Because of the unique nature of the disease, even those who have suffered only minimal exposure are at risk of contracting the disease.  In effect, virtually everyone has some risk of contracting Mesothelioma. 

But this sort of statement perhaps oversteps the bounds of rationality.  While it is certainly true that individuals who have been exposed to small amounts of asbestos for relatively short periods of time have contracted the disease, this is a rarity rather than a regularity.  In fact, the vast majority of Mesothelioma cases involve individuals who were exposed to airborne asbestos fibers for intense and extended periods of time.

The industries most in danger of prolonged exposure and thus of contraction are shipbuilding trades, asbestos mining and milling, textile manufacturing, insulation work in construction, and brake repair personnel. There are, however, some other minor factors which can affect the likelihood of contracting the disease.  Among these is radiation exposure.  There have been causes in which individuals who were exposed to radiation have subsequently displayed signs of and ultimately contracted mesothelioma.  However, empirical studies to attempt to verify this correlation have not proven out this claim very strongly. 

Another more certain cause of the disease was the taking of the Polio vaccine between 1955 and 1963.  Some batches of this vaccine were contaminated with Simian Virus 40 which has been detected in a host of rare cancers including Mesothelioma.

Those involved in construction or who lived in homes in the Cappadocian region of Turkey are also particularly at risk.  In this region, homebuilders used Erionite, which is a type of zeolite silica stone.  Exposure to the fibrous strands of this building material have led to an annual death rate of roughly 1% of the population which dies of mesothelioma each year in Turkey.  

One of the most influential factors affecting Mesothelioma contraction is genetics.  Some individuals who have been exposed to long periods and high quantities of asbestos have not contracted the disease.  As a result, doctors have concluded that genetics play a major role in determining whether or not patients contract the disease.  Unfortunately, the gene variability which offers some resistance to the disease also means that some are particularly vulnerable to asbestos exposure.

Mesothelioma is serious cancer.

Mesothelioma is serious cancer and asbestos is main cause. During in 1940 and 1950s constructions community used asbestos as the best thing to happen after cement for construction industry. Asbestos was applied greatly in insulator and ceiling tiles in homes, schools and factories because to high degree of stability and resistance to very high temperatures.

Nonetheless, asbestos is capable of causing harm, contaminant. It has trend to break into small parts and remain stay in the air for longer durations. For individual who is that comes in contact it, becomes attackable to serious disease to lung cancer or mesothelioma lung cancers.

What types of Mesothelioma?
Name of Mesothelioma, asbestos related cancer, acquires its name from the mesothelium cells that are responsible for protecting and enabling easy movement of our vital organs such as lungs, heart and the abdomen in the body. Mesothelioma is generally of three types, pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma.

If a person is suffering from hoarseness, difficulty in breathing, loss in weight, coughing, blood in sputum, chest pain, weak muscles, reduced tactile sensitivity, he may be suffering from Pleural mesothelioma or the cancer of lining of the lungs. This is the most common type of mesothelioma and almost two-thirds of the mesothelioma patients suffer from pleural mesothelioma. The Peritoneal mesothelioma or cancer of the lining of the abdomen causes impaired bowel motion, bloating, swelling in feet, and nausea. This is less common among mesothelioma patients and it affects one-third of the mesothelioma patients. Pericardial mesothelioma is of the cancer of lining of the heart. It is also caused because of asbestos exposure. However, its prevalence is rare. Pericardial mesothelioma manifests in the form of chest pain, palpitations and cough.

Lawsuits related to Mesothelioma:
The dangerous consequences of long term contact with asbestos and its linkage to mesothelioma cancers has led to several lawsuits against its manufacturers. The manufactures were claimed by the attorneys that they were aware of the capable of causing harm affects of asbestos exposure and yet persisted with its use for profit motives. This is the reason why juries have ordered stringent awards in many mesothelioma and asbestos related lawsuits.

Asbestos - Mesothelioma

Asbestos is the biggest work place killer today.  Those who have worked with asbestos or who are regularly in contact with someone who has are at risk from asbestosis, lung cancer and mesothelioma.  All these are fatal respiratory diseases which are extremely difficult to cure.  Research is being carried out in various research labs all over the USA and many pharmaceutical companies are also endeavouring to find new drugs and treatment methods.


One rare disease caused by asbestos which is becoming increasingly common is mesothelioma.  Although unknown by many today, it is almost certain that awareness of this disease will be broadcasted worldwide because of its increasing occurrence in men aged between 55 and 70.  Many of these men are now lodging multi million dollar lawsuits against the companies who subjected them to asbestos.  Those most at risk from mesothelioma are those who have been in regular contact with asbestos dust and fibres without sufficient protection.  Just a couple of months of exposure to asbestos can lead to mesothelioma 30 years later.  The latency period (amount of time the disease takes to start taking effect) of mesothelioma is 30 - 50 years which is one of the reasons it is so difficult to cure because it is very difficult to tackle in its early stages.  Another reason it is so difficult to cure is that its early symptoms are characteristic of many other more common diseases such as pneumonia.


Mesothelioma symptoms include:


- Chest pains
- Coughing that worsens over time
- Weight loss
- Shortness of breath
- Coughing up blood
- Nausea and vomiting
- Fatigue
- Wheezing
- Lung infection
- Swollen lymph nodes
- Loss of appetite


A patient will feel symptoms depending on which type of mesothelioma he or she has got. In the next 35 years it is estimated that over 1 million people will die from asbestos related diseases in developed countries.  Most of these people will die from lung cancer and mesothelioma as these two are the most prolific asbestos related diseases.
