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.


Mesothelioma treatments: What are my options?

Clinical research to treat malignant mesothelioma is very active and although no treatment has yet proved entirely successful, there exist a range of treatments available to individuals diagnosed with the disease.  There are three types of standard treatments used to treat malignant mesothelioma which include: surgery, radiation therapy, and chemotherapy. 

Surgery
Surgery for malignant mesothelioma is divided into a number of sub-classes, which are specially designed to limit the disease for individuals with particular strains of the disease.

Extrapleural pneumonectomy is a severe form of surgery in which the entire lung and a portion of the lining of the chest, the diaphragm, and some or the entire sac which surrounds the heart is removed.

Wide local excision is a form of surgery which targets and removes the cancer and a limited amount of the healthy tissue surrounding the cancerous region. 

Pleurectomy and decortication removes part of the covering of the lungs, as well as the lining of the chest and portions of the outside covering of the lungs.

The surgical procedure pleurodesis is a distinct technique insofar as it employs a blend of chemicals and/or drugs to create an intentional scar between the layers of the pleura.  Post surgery, the space created by the scar must be drained, using either a catheter or chest tube, and is then filled with a chemical which inhibits the accumulation of fluid in the pleura cavity.

Radiation
The second primary medical technique used to fight the development of malignant mesothelioma is radiation.  Radiation therapy, as applied to malignant mesothelioma uses the same basic technology as other forms of medical radiation insofar as the technique employs high energy x-rays to kill cancer cells.  The process is divided into two broad categories:

External radiation therapy is a technique in which a machine sends radiation in a targeted stream at a certain portion of the body, and in so doing it kills the cancerous cells in its purview.

Internal radiation therapy, by contrast, uses not an external machine, but rather needles, seeds and catheters to place radioactive substance directly on or near the cancer.  While the precise method of implementation will of course depend upon the type and stage of the illness,  what is constant within this category is that the goal is to get the radiation placed directly onto the cancerous area and in so doing provide a more concentrated and directed dosage.

Chemotherapy
The third standard malignant mesothelioma treatment is Chemotherapy.  Chemotherapy uses drugs which target cancer cells and stop them from dividing and thus prevent their growth. 
In systemic chemotherapy, the drug can be taken by mouth or injected, but either way the goal is to have it reach cancer cells by means of the body’s own blood circulation system.  In regional chemotherapy, the drug is placed directly onto the target area.  And finally, combination chemotherapy involves the use of two or more anticancer drugs which can be administered either orally or through injection. 

Malignant mesothelioma is a difficult disease for anyone to bear, however, educating oneself as to the options available is an important step for making the process more manageable.


Symptoms of Mesothelioma

The term “Mesothelioma” in medical terms is defined as form of cancer that proliferates at a very fast rate after it has been diagnosed, which affects the mesothelial cells in the body. After detailed study of this disease by several scientists all over the world, it has been concluded that in most of the cases the reason is the direct contact with loose asbestos particles. This disease is generally known to be derived from an abnormality that arises from inhaling the loose asbestos particles suspended in the air for a very long time. The chances of the patients, diagnosed of mesothelioma, have very bleak chances of survival which is not more than one or two years and if it has been detected long back and rigorous medication has been started on the patient then the patient is likely to live for about five years.

There are three types of mesothelioma but the symptoms of the diseases depend on their kinds. The symptoms vary from one-another but the general symptoms that are found in patients suffering from different types of mesothelioma are weight loss, chest pain, loss of appetite, short breath , plain cough and cough with blood. Diagnosing mesothelioma in its initial stages is not possible because symptoms surface very late and that, these symptoms are no special signs indicating the particular disease but are common for other diseases too.

Generally the symptoms of mesothelioma resemble to that to any other normal lung diseases. Most of the symptoms arise in the lungs, where the mesothelial cells covering the lungs and the cavity between them are affected due to prolonged inhalation of asbestos fibers. Consulting with the physician is very necessary from time to time and necessary test must be conducted to detect the disease.

The main symptom of mesothelioma is a constant pain in the chest which is followed by short breaths and difficult breathing because of accumulation of fluid in the chest, which makes breathing all the more difficult. Some of the other symptoms of the disease include abnormalities in the lungs, which can be diagnosed under proper supervision of the doctor with a chest CT-scan.

Basically, the disease of mesothelioma advances in four stages. In the first stage, begins the formation of the tumor in the area of lining of the lung and doesn’t exceed from one side of the lung. And then in the second stage the tumor extends to other organs in the chest cavity, such as heart. Then in the third stage its extents to the other abdominal organs affecting all the other organs too. Finally in the fourth and the last stage the tumor extends to all parts of the body and affects all the parts adversely. These are some of the symptoms of the disease of mesothelioma, by which the disease can be tracked in the initial stages of its occurrence.

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 Cancer – An Overview

The cause of mesothelioma cancer:
Mesothelioma is a cancer caused by exposure to asbestos without sufficient protection over one’s mouth and nose.  Asbestos is a fibrous mineral which was discovered in the 1860s but not properly used until the 1930s.  Asbestos was used hugely in construction due to its property of being fireproof even at high temperatures.  It was not until the 1960s that it became clear that asbestos was causing a number of diseases.  These diseases include mesothelioma, asbestosis and lung cancer.

Asbestos as the cause of mesothelioma:
hen exposed to asbestos without sufficient protection, a person will inhale many tiny asbestos fibres that are suspended in the air.  These will pass into the respiratory system and get most probably get lodged in the lining of the lungs.  An accumulation of these fibres can cause the cells around it to become abnormal and this can lead to mesothelioma.  Through the lymphatic system, asbestos fibres can become lodged in the lining of the abdomen or in the lining of the heart.

The suffering endured by patients of mesothelioma:
The symptoms of mesothelioma vary depending on what type of mesothelioma a patient has.  However, there are several common symptoms of all types.  These include chest pain, shortness of breath, coughing, coughing up blood, weight loss and loss of appetite.  These symptoms usually take affect only when the mesothelioma cancer has fully matured and developed.  Due to the fact that these symptoms are frequent for a number of more common diseases such as pneumonia, mesothelioma is very difficult to diagnose in its early stages.

The treatments available for mesothelioma:

As yet, all treatments for mesothelioma have a low success rate.  The effectiveness of treatment depends largely on how aggressively and early the cancer is treated.  If treated in its later stages when it has fully developed, it is extremely difficult, almost impossible to cure.  Treatments include surgery which comes in two forms, aggressive surgery and palliative procedures, radiation therapy, chemotherapy and dual therapy which is a combination of all three main treatments combined.  Dual therapy has shown the most promising signs so far as a curer for mesothelioma.

Mesothelioma research:
Research is being undertaken in numerous research labs all across the United States although so far no breakthroughs have been made.  Many pharmaceutical companies are also endeavouring to find new drugs for chemotherapy.  Researchers have recently predicted that a long awaited new treatment method for mesothelioma is on the way to being discovered.


Mesothelioma – Your Basic Information

Mesothelioma is a form of cancer that is becoming more and more common. The most common cause of this cancer is exposure to asbestos. When constantly exposed with insufficient protection, asbestos dust and fibres affect the mesothelial cells which make up the mesothelium. The mesothelium is the outer lining that protects some of the body’s most vital organs such as the heart and lungs. The mesothelial cells become abnormal after lengthy periods of constant exposure to asbestos causing an array of problems.

Due to the latency period and symptoms of this cancer, mesothelioma is very difficult to diagnose. Mesothelioma takes decades to mature and develop fully and this is why many elderly men who were exposed to asbestos thirty years before are just discovering they have the cancer. A lot of these men are currently lodging multi-million dollar lawsuits against the companies that exposed them to the dangers of asbestos without sufficient protection.

The organs that are affected most by mesothelioma are the lungs. The most common type of mesothelioma which is called pleural mesothelioma affects the lining of the lungs and can cause symptoms such as coughing, breathing and swallowing difficulties, shortness of breath and fever. Another area that can be affected by mesothelioma is the abdomen. This is less common and this is known as peritoneal mesothelioma. Symptoms of peritoneal mesothelioma include nausea and vomiting, weight loss, fever, bowel obstruction, loss of appetite and general pain in the stomach area. The last and least common type of mesothelioma is known as pericardial mesothelioma and it affects the heart and the tissue surrounding it. Symptoms of this form of the cancer include palpitations, breathing difficulties and persistent coughing. Generally, the symptoms of mesothelioma are typical of many other diseases and this makes it very difficult to diagnose.

There are treatments for mesothelioma although these are usually unsuccessful. If the cancer is treated aggressively in its early stages then there is a good chance of a patient surviving. However, due to the difficulty to diagnose mesothelioma, the cancer is not normally found until it is too late. Treatments that are used for mesothelioma include surgery, radiation therapy, palliative therapy and chemotherapy. Research for additional treatment of mesothelioma is being done at various cancer centers all over the United States as well as by pharmaceutical companies.

Mesothelioma

Tragically the word mesothelioma is becoming more and more well known, the mere mention of it striking fear into all of us for we know that it is associated with death.  Asbestos is the reaper, mesothelioma its hand maiden. 

Asbestos, the wonder product of the fifties is now recognized as an enemy of the twentieth century. A ruthless enemy which will kill more people than the war.  Men, women and children will fall victim to its prey, innocents who have at some time in their lives inhaled asbestos dust. 

Most of us have been in contact with products containing asbestos in our life times.  We sat in asbestos class rooms, stood beside our fathers as they cut asbestos fencing, pulled up old linoleum with asbestos clogged to the back of it.  Visited the local tip where broken sheets of it lay open to the wind.

Records show that there are a higher number of people afflicted with asbestosis and mesothelioma who have directly worked in asbestos mines, ship yards and companies making products from asbestos; however there are a large number of people afflicted, who have never worked in these industries.  Their contact with asbestos, due to the dust brought home on their husband’s clothes or from the asbestos tailings placed around mine houses and town perimeters.  But the tragedy does not end there, children innocently playing in their own back yards played amongst the asbestos tailings as children elsewhere play in the sand.  They had no way of knowing that their sand was asbestos blue.  A good bath at the end of the day may have removed the dust from the skin but the dust in the lungs remained and would lay dormant for many years before claiming its deadly legacy.

Without warning, a healthy individual suddenly becomes short of breath, x-rays reveal fluid on the lungs and the night mare begins.  Questions are asked and you answer, Yes, I was exposed to asbestos dust but I was only in the town for a few short months and that was over 40 years ago.  How can this be? This is the most perplexing thing about mesothelioma.  Why is there such a long period of time between inhalation of asbestos dust and onset of the disease?  What triggers a strong healthy body to suddenly succumb to it?  What can we do to prevent this from happening?

Blood tests are now available to determine whether mesothelioma is present in the body, before a person is aware of any symptoms.  This is an amazing breakthrough and perhaps the first step towards curing the disease before it becomes terminal.  Recently mesothelioma was cured in a mouse and attempts to give it back to the mouse were unsuccessful.  This too is exciting stuff and holds a glimmer of hope for us all. 

I have witnessed first hand the devastation of mesothelioma. My husband was a strong and virile man who rarely had a sick day in his life.  Suddenly at the age of 52 he became short of breath and was subsequently diagnosed with pleural mesothelioma.  He had lived in the asbestos mining town of Wittenoom in Western Australia for a few short months at the age of seven.  The asbestos dust he inhaled then, took forty five years to become lethal.  I still find this hard to believe.

Despite his prognosis of three to nine months, Brian survived for two years.  He was 54 years old when he died.

Living In Fear Of Mesothelioma

Mesothelioma
Mesothelioma is the medical name for cancer of the lung, and is usually caused by exposure to asbestos. Symptoms my not appear for up to 50 years or so after exposure to asbestos, and people who haven't had any contact with asbestos for many years, are now showing signs of having this deadly disease. The symptoms are usually shortness of breath, coughing, and chest pains and feeling very tired.

Why should I be scared of it ?
As a small child, I used to live near a factory which used asbestos to make fire-proof products and other insulating materials for the building industry. I believe that asbestos was also used in the manufacture of break linings. I can remember seeing the asbestos dust that spewed out of the factory covering the surrounding area (including part of our school playground) with this deadly snow like powder. Of course, as we were just kids at that time, we had absolutely no idea just how deadly this dust was. We even played in it completely unaware of its dangers.

The Horror Came Later.
It wasn't until years later after the factory had been closed down, that we began to see the full horrors of this white snow looking powder, we had played with as children. By this time I was much older, and the dangers of asbestos had been given massive coverage by the media, so I was now aware of what could happen to myself and hundreds of other people who lived in the same area as this factory in years to come.

TV Documentary.
This factory received national television coverage, and on one program they interviewed families who had suffered due to the problem of asbestos. I was shocked to see that I knew some of the people who had lost family members due to developing mesothelioma, in fact I actually went to school with some of the people who took part in the program. The program showed old photographs of the area around the factory (including my old school) covered in powder, and it really did look like it had been snowing. When you see all of this on television it really does make you just a little bit worried, especially when you have been in contact with asbestos like I have.

Treatments.
If mesothelioma is diagnosed early enough, a cure is possible with a combination of surgery, chemotherapy, and radiation. However, in the case of a more advanced illness a cure is not possible, but with the right treatments the illness can be slowed down dramatically and medication can be used to ease any pain.

X-Rays.
As a precaution I did have x-rays a few years ago just to put my mind at rest, and thankfully they were all clear. The doctor recommended that I should have x-rays on a very regular basis just to be on the safe side. So, at the moment everything is ok, but I will always be just a little bit worried of what might happen in the future.
