Mesothelioma: How Do Doctors Diagnose Asbestos Cancer? Part 1

As we discussed in our previous article, you might have been exposed to asbestos airborne particles if you have been building ships, working with heat insulation and changing old brakes pads. There are many dangerous occupations exist, such as, asbestos plant workers, automobile mechanics, boiler workers, plumbers, drywall workers, electricians insulators, painters, even hairdressers and teachers. Many other professions might give an occasional exposure to the asbestos particles.

As the consequence of asbestos exposure you may get asbestosis, but you may also start do develop mesothelioma - relativity rare but deadly type o cancer.

So, how do doctors diagnose the mesothelioma?

When you see your doctor, the first think he does to suspect the mesothelioma is asking about your occupational history. The paramount importance is to catch the asbestos cancer in the early stages of the disease, so time is of the essence. The survival rate is eight to twelve months on average. However, catching and treating the mesothelioma early at some cancer centers gives better results.

Doctors look for signs and symptoms of the cancer. The mesothelioma symptoms often delay up to 20 and more years after asbestos exposure. Yet, in rats intra-pleural introduction of asbestos chrysotile fibers may cause mesothelioma in several months.

People with mesothelioma complain on breath shortness, persistent cough, sputum, and chest pain. The pain comes from pleura - the lungs lining that is very sensitive to irritation. Mesothelioma tends to cause fluid accumulation in the pleural cavity.

Peritoneal mesothelioma causes weight loss, pain and ascites (belly swelling due to fluid in the abdominal cavity). Peritoneal mesothelioma also may block bowels and cause all kinds of troubles with gut obstruction. As many cancers, asbestos cancer also changes blood clotting, causes blood cells decrease (anemia), night sweats, and fevers. Ascites may lead to nausea and feet swelling. Spreading of the cancer will bring pain, difficult swallowing, and neck swelling. This symptom happens because of compression of some great veins going to the heart in your chest. In general mesothelioma symptoms are not very specific. They may characterize any other type of cancer as well as many other non-cancerous diseases. This problem delays diagnosis. Sometimes patients think that they have viral pneumonia. Some patients don't have any symptoms at all. Mesothelioma in advanced stage, as well as majority of cancers, will cause fatigue.

An x-ray may show a fluid accumulation.

What is a pleural effusion? Pleural effusion means the accumulation of fluid between the pleura on inside chest wall and diaphragm and pleura covering lungs. What is pleura? Pleura is the thin layer of special cells covering the lung and inside of the chest wall. It has an idea of closed plastic bag with some small amount of fluid inside. Basically, this bag helps lungs to slide easily against chest wall during expansion from breathing. The membranes of pleura consist from mesothelial cells. Exactly these cells produce a small amount of the lubricant. The amount of fluid is always in balance. Extra pleural fluid is quickly reabsorbed. When there is too much fluid, it is the effusion. Abdominal cavity has similar lining named peritoneum, which covers abdominal organs the way pleura covers the lungs. Mesothelioma leads to fluid build up, which is caused by cancer cells irritating the pleura or peritoneum. This fluid leads to sickness in your abdomen or difficulty breathing.

Transudation is a pleural effusion with clear fluid. It usually results from imbalance of fluid production and removal. It is more characteristic for some other disease. Doctors would think first about congestive heart failure. Mesothelioma would rather cause an exudate. Exudates are a cloudy pleural effusion with many cells and proteins. Exudates happen after the pleura is irritated and inflamed, as it happen in mesothelioma. To check the type of effusion, doctors would stick a needle and get the fluid sample. This stick is called diagnostic thoracentesis. The fluid will be checked in the lab. If mesothelioma is the cause, cancer cells may be found in the fluid

Why shortness of breath develops? The dyspnea (breath shortness) happens exactly because too much fluid is accumulated and press on the lung, pushing it away form the chest wall inside and thus making the lung smaller. Also the pain from inflamed pleura prevents patient from deep breathing. The receptors in inflamed pleura also cause dry cough. Listening to the lungs with a stethoscope reveals decreased breath sounds. Tapping on the chest sounds dull. This all is the consequence of fluid accumulation.

During your doctor's visit, you should discuss your concerns about asbestos exposure in the past. Your doctor should check the area of pain and swelling; he also should listen to your breath sounds and check for fluid collection. If your doctors suspect the effusion he may send you for tests and X-rays or refer to a specialist.

If a doctor suspects mesothelioma, he dose not have many specific tests on hands. Many of the usual tests may show no results in mesothelioma. Simple chest x-ray does not always show small pleural effusion. A lateral decubitus film may be required for smaller effusions (the same x-ray but the side view). Otherwise CT scan or ultrasound may show the effusion.

Mesothelioma Cancer Stages Explained

Mesothelioma cancer is a type of cancer that attacks the lungs and chest cavity. Also known as asbestos lung cancer, it forms deadly tumors where mesothelial cancer cells form a protective lining over the lungs, heart, and abdominal organs. It is a type of lung cancer that takes many years to develop and produce symptoms. Roughly 3,000 cases per year (mostly men over the age of 40) are reported. It is estimated that number will grow to about 300,000 cases before 2030.

Types of Mesothelioma Asbestos Cancer

Epithelial mesothelioma is a rare and fatal form of cancer affecting the membrane lining of the chest cavity, heart, lungs, and abdominal cavity. There are three forms of epithelial mesothelioma: the most common is Pleural Mesothelioma, the second most common, Peritoneal Mesothelioma (accounting for only a quarter of the cases), and the rarest form, pericardial mesothelioma.

Pleural mesothelioma, the most common type of this disease involves the pleura, a thin membrane located between the lungs and the chest cavity. The pleura provide a lubricated surface so that the lungs do not rub and chafe against the chest walls. There are two types of pleural mesothelioma the first being 'diffuse and malignant'. This type is cancerous and is generally fatal within a year of diagnosis. The second type is 'localized and benign' and is generally non-life threatening. It can usually be removed through surgery.

Lung Lining cancer is not to be confused with lung cancer. In lung lining cancer, the effected area of the body is called the mesothelium, a thin membrane that covers many of the internal organs of the body. The mesothelium of the lungs is called the pleura. Lung Lining cancer is also sometimes called mesothelioma after the area in which it occurs.

This thin membrane is comprised of two layers - one that surrounds the organ and another that forms an exterior sac around the first layer. Between the layers of the mesothelium is a fluid that allows vital organs to glide easily against objects that come in contact with them.

Localized pleural mesothelioma is not always caused by asbestos exposure. However, if it has spread to other parts of the body, for instance the lymph nodes, lungs, chest wall, or abdominal organs, then it is considered malignant and is more often than not the result of asbestos exposure.

Peritoneal mesothelioma appears as a tumor in the peritoneum membrane of the abdomen. This type of mesothelioma is very rare, comprising less than a fourth of all known cases of the disease. There are no effective treatments for this condition, and most patients live less than a year after diagnosis.

Mesentery cancer is likened to peritoneal cancer (mesothelioma). This cancer primarily affects the sections of the peritoneum that attach different organs to the wall of the abdominal cavity, (i.e. mesogastrium for the stomach, mesojejunum for the jejunum). Mesentery cancer includes all abdominal peritoneal extensions. Tumors rarely originate in the actual mesentery, though it is a frequent route for the spread of mesothelioma through the abdominal cavity.

Pericardial mesothelioma is the rarest form of mesothelioma, affecting the membrane around the heart (called the pericardium or pericardial sac). In this disease, solid masses and effusion (fluid) develop around the pericardium. Not all effusions are strictly related to mesothelioma.

The Causes

Mesothelioma cancer is caused by exposure to asbestos fibers or dust. Workers in the asbestos industry are prime targets for attracting this deadly disease. Asbestos fibers enter the body, either by breathing in the tiny asbestos fibers or by swallowing them. The fibers cause healthy cells to mutate into cancer. Since the body is unable to dispel these fibers, the lungs become inflamed (asbestosis). This condition worsens and eventually becomes malignant. Asbestos exposure is thought to be responsible for roughly 75% of all cases of lung lining cancer.

Symptoms

Mesothelioma is a very difficult cancer to detect in early stages. The early symptoms tend to be generic and even nonexistent in some cases, and it can take as much as 15 to 50 years after exposure to develop. The first symptom is often constant chest pain, followed by coughing, lung damage, and shortness of breath. Patients who have peritoneal mesothelioma (a less common form of mesothelioma) generally experience abdominal pain, loss of appetite, nausea, and abdominal swelling, often in addition to the symptoms of pleural mesothelioma. They may also develop bowel obstruction or further breathing obstruction.

Stages and Diagnosis of Mesothelioma

There are three staging systems used to determine treatment for mesothelioma: Butchart System, TNM System, and the Brigham System

Butchart Staging System

The Butchart System is the oldest system and the most common. This system concentrates upon determining the extent of primary tumor mass and divides mesothelioma into four stages.

Stage I of the Butchart System consists of the presence of mesothelioma in the lining of the right or left lung and may also involve the diaphragm on the same side. Stage II includes the progression of mesothelioma into the chest wall, esophagus, or lung lining on bother sides. There may also be lymph nodes in the chest. The onset of Stage III begins when the mesothelioma surpasses the diaphragm into the lining of the abdominal cavity or peritoneum. In this stage the cancer may also affect the lymph nodes extending beyond those in the chest. Doctors identify Stage IV, the final stage, when evidence of the spread of cancer to other organs (metastasis) is confirmed.

TNM System

Stage I of the TNM System involves the lining of the right or left lung, pericardium, or diaphragm on the same side. At this stage, lymph nodes are not involved. Stage II begins when mesothelioma spreads from the lining of the lung on one side to a lymph node on the same side. At this stage, the cancer may also spread to the lung, pericardium, or diaphragm on the same side. Stage III begins when mesothelioma is present in the chest wall, muscle, ribs, heart, esophagus, or other organs in the chest on the same side as the primary tumor. In the final stage, Stage IV, the mesothelioma has travelled into the lymph nodes in the chest on the side opposite the primary tumor, into the lung opposite the primary tumor, or directly into the organs in the abdominal cavity or neck. Metastasis is the final result in this stage.

Brigham System

The Brigham System determines the resectability (the ability to surgically remove) the mesothelioma mass. In Stage I the tumor is resectable, while lymph nodes remain unaffected. In Stage II the tumor remains respectable but the mesothelioma affects the lymph nodes. In Stage III the tumor becomes unresectable. It has penetrated through the diaphragm, or peritoneum. Stage III can occur with or without lymph involvement and extends into the chest wall and heart. Stage IV occurs when doctors discover metastatic disease involving distant organs.

After doctors identify the stage of a patient's malignant mesothelioma, the patient and doctor consider the various treatment options available. Mesothelioma treatment programs are contingent upon many factors, including the stage of the cancer, the location of the cancer, the spread of mesothelioma cancer, the characteristics of the cancer cells under a microscope and the patient's age and concerns.

Not Only Asbestos Causes Mesothelioma Lung Cancer

Mesothelioma lung cancer is usually associated with asbestos exposure. In fact there are many other risk factors that cause mesothelioma cancer. One of them is the erionite. Erionite is a naturally occurring fibrous mineral that belongs to a group of minerals called zeolites. Zeolites are hydrated aluminosilicates of the alkaline and alkaline-earth metals.

Erionite was used in the past as a noble metal-impregnated catalyst in a hydrocarbon-cracking process. It was studied for use in fertilizers and to control odors in livestock production, because of its ability to selectively adsorb molecules from air or liquids. In many countries erionite blocks were used (and may be are still used) as building material or in stucco pastes and whitewash.

Erionite was mentioned for the first time as a mesothelioma lung cancer risk factor in 1975, when Turkish government presented a study that uncovered a high incidence of a rare malignant mesothelioma in lung tissues of people in certain small villages in the Cappadocia area in Turkey's central mountainous region. In two small villages the mesothelioma lung cancer accounted for 43% of the deaths during 23 years period of study. Erionite fibers were found in biopsies of lungs of the mesothelioma cancer afflicted people. Comparing this to a 9.7% rate of death from this disease among asbestos insulation installers shows how anomalous this condition was.

Further studies showed erionite causes similar diseases in laboratory animals. When researchers at Mt. Sinai Hospital injected rats with the same dosage of erionite that they used for asbestos, the rats didn't live long enough to get mesothelioma cancer. At a much-reduced dose, the rats did get cancer. Erionite is probably the most toxic known mineral - a milligram of fibers in the lungs is lethal.

Today erionite is considered so hazardous that the EPA requires any one who intends to manufacture, import or process any article containing erionite to notify the E.P.A. 90 days in advance. This gives the EPA a chance to review, limit or prohibit that activity.

Erionite is no longer mined or marketed for commercial purposes.
Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc.) So potential occupational exposure to erionite occurs during the production and
mining of other zeolites.

And there are questions:

Are there other mineralogical hazards like erionite and asbestos?

Should we expected mesothelioma lung cancer increases not only from asbestos exposure after another 20 - 30 years?

Asbestos Exposure and Mesothelioma Cancer

Asbestos is a naturally occurring mineral consisting of strong, flexible fibers, which can be partitioned and woven into insulation material. Mining of asbestos began late in the 19th century and the use of asbestos escalated in the 1940's. Asbestos exposure is the primary cause of mesothelioma. Tiny particles of asbestos invade the body through inhalation or ingestion and become embedded in the linings of body cavities. Asbestos limits and stricter protocols for workers handling asbestos were instituted in the 1970's, when the health risks started to become apparent.

Mesothelioma occurs when the cells of the mesothelium, a two-layer lining of the internal organs, become abnormal and attack the organ or spread to other parts of the body. There are three malignant types of mesothelioma:

· Pleural: This form originates in the chest cavity and may involve the lungs. It is difficult to detect and most often spreads to other parts of the body. It is the most common type, responsible for approximately 70 percent of mesothelioma diagnoses. The survival rate is 17 months after symptoms commence for 92% percent of victims.

· Peritoneal: The type begins in the abdomen cavity lining and advances to the liver, spleen and bowels. The survival prognosis is ten months after symptoms appear. About one-quarter of all mesothelioma cases are peritoneal.

· Pericardial: This manifestation involves the lining of the heart. Eventually the cancer progresses until the heart cannot deliver oxygen to the body. It is the rarest form and accounts for approximately 5 percent of all cases.

Benign mesothelioma is a separate form of mesothelioma where a non-cancerous, non-spreading tumor develops and invokes symptoms similar to those of malignant forms of mesothelioma. Extensive testing is required to differentiate between malignant and benign. Benign mesothelioma occurs in less than 10 percent of all cases.

Mesothelioma lies dormant in the body's system for a substantially long period of time, typically between 20 and 50 years, before symptoms begin. The age at the time of exposure, levels of exposure and duration of exposure are all risk factors. Young workers with high levels of exposure over many years are at greatest risk. People that fall within this category are more likely to die from one of asbestosis, lung cancer or mesothelioma.

Asbestos exposure still exists in our environment today. The US Environmental Protection Agency estimates 700,000 buildings, including schools, in the United States contain asbestos insulation.

A jury in Baltimore recently awarded a mesothelioma victim $1.178 million in compensation. The Plaintiff was exposed to asbestos during the 1960s and '70s.

If you or a loved one has been exposed to asbestos and diagnosed with mesothelioma, it is imperative you seek legal advice from a knowledgeable attorney as soon as possible.

Exposure To Asbestos Could Cause Mesothelioma Papillary

Mesothelioma is a malignant tumor that affects the epithelium or lining of the heart, abdomen or lungs. Asbestos Mesothelioma Papillary is a cancer that occurs due to exposure of the human body to asbestos. It is not common but when the disease occurs, the malignant cells that infect the lining of the body cavities multiply at a rapid rate. The consequences are complications occurring in the lungs or other related organs and the spreading of the cancer cells to adjoining parts of the body.

When a person or a close relative is diagnosed with the disease, it is natural to be shocked and dismayed. If you have been diagnosed early enough, there is hope. Early detection helps in getting the right treatment at the right time when you can be taught to manage the disease. This helps stem the disease to a large extent.

Extensive research proved that asbestos was the cause of Asbestos Mesothelioma Papillary. Subsequently, there has been a ban on asbestos and products containing asbestos from the 1970s. It was noticed that the disease mostly affected workers in the asbestos manufacturing units and other factories that used the material extensively. It was proven that inhalation or ingesting the fibers that make up asbestos caused this dreaded disease.

The symptoms of this cancer are hardly noticeable. Asbestos Mesothelioma Papillary seems to creep up on you, since the symptoms take a long time to manifest themselves. A person may have had asbestos exposure at a very young age but the symptoms could occur after two decades and sometimes even after five. It is therefore wise to have a specialist check you out from time to time, in case you have had any kind of exposure to asbestos or products containing asbestos.

The characteristic symptoms of the disease are related to breathing. If you have trouble breathing, or gasp for air after a slight exertion, you should consult a doctor. If you begin to lose weight or have a persistent cough, it's time to get medical help. If you don't have a peaceful sleep at night because you experience chest pain or pain in your abdomen, that's the time to worry.

When the cancer cells proliferate, the body gets weaker and you tire easily. The body's metabolism is affected. You lose weight because of the body's inability to assimilate beneficial nutrients. The rampant cells soon affect organs around the infected one. In consequence, the patient experiences intense pain, difficulty in swallowing and edema. The latter is apparent on the neck and face. However, the symptoms are largely dependent on the area affected. When the abdomen is affected, including all the organs the cavity holds, the cancer is referred to as Peritoneal Mesothelioma. In this case, the abdomen swells up because of fluid retention. In the case of Asbestos Mesothelioma Papillary, when the lungs are infected, the surrounding organs like the larynx could get affected and swallowing becomes a painful experience.

As has been said before, Asbestos Mesothelioma Papillary can be treated. If the person has worked in an asbestos facility or has been exposed to the fibers at all, even if it has been years ago, it is best to consult a doctor. If you find anything unusual in your bodily functions, even if the symptoms don't seem serious, have yourself checked out. Prompt detection could save your life.
