What is Positron Emission Tomography?
Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves the acquisition of physiologic images based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. The subsequent images of the human body developed with this technique are used to evaluate a variety of diseases.
PET scans are used most often to detect cancer and to examine the effects of cancer therapy by characterizing biochemical changes in the cancer.

Pleural mesothelioma is a malignant tumour that develops in the pleura. The pleura is a very thin layer of tissue that wraps itself around the lung and lines the inside of the chest wall. Mesothelioma may occur with very little asbestos exposure. Even owner/renovators of fibro homes have developed mesothelioma, as have wives who regularly shook out asbestos workers’ overalls ready for washing.
Mesothelioma tends to grow into the tissues of the chest wall, interfere with nerves and may produce fluid that can compress the lung.

Know Your Rights! - Mesothelioma

If you are suffering from mesothelioma, as a victim, you are entitled to compensation from the manufacturers of asbestos. Please click on the following links to find out more about your legal rights.

Know Your Rights

If you are reading this, you or someone you know is probably suffering from mesothelioma. In the United States, the disease is always universally caused by asbestos. If you or someone you know has been diagnosed with mesothelioma, it is important that you take action.

Your Right To Compensation

Victims of asbestos-related mesothelioma and lung cancer are entitled to compensation from the manufacturers of any asbestos containing product to which they were exposed in sufficient quantities to cause disease. The amount of compensation ultimately received varies in each individual case, but it is often a significant amount, depending on the product exposures that can be identified. This compensation is not a windfall. It is, rather, an attempt to make you whole in light of this devastating illness. Liability exists because asbestos product producing companies often covered up the fact that asbestos is hazardous, and made billions of dollars peddling deadly products. You, the unsuspecting user, are severely injured as a result.

Anyone who was injured as a result of their exposure to asbestos has a potential legal claim against the manufacturers of asbestos products. This can be significant for several reasons. The medical costs associated with treating a disease such as mesothelioma can be staggering. Moreover, legal compensation is a means by which many victims of mesothelioma provide enough money to support a spouse or loved one, or to leave behind a legacy (for example, to help put their grandchildren through college).

Why You are Entitled to Compensation: The History of the Asbestos Industry

The asbestos industry has a dirty little secret. For centuries, there has been evidence that asbestos caused respiratory diseases in humans. By the 1930’s, however, the asbestos industry was selling millions of dollars worth of asbestos insulation. Asbestos, a mineral, was plentiful and inexpensive. Best of all, it was a terrific insulating material. It was used in all sorts of products - pipecovering, cement, gaskets, blankets, and the like. It was even used in clothing, joint compound and other building materials, automotive products and other various uses.

There was only one problem-people who worked with it had a habit of dying from respiratory illnesses. The medical literature of the 40’s and 50’s were already developing a wealth of information about the hazards of asbestos. The medical and industrial fields were well aware of the dangerous nature of asbestos by this time.

It was around this time that the asbestos companies began to gather and form trade associations in order to strengthen their industry. Long ago, the asbestos trade associations and industry giants began to fund scientific studies to prove that asbestos was safe. Their scientists, however, came back with a different conclusion. Asbestos, they warned, was a highly toxic carcinogen. It caused respiratory illnesses, including cancer, in laboratory animals and, it was believed, in humans.

Faced with this evidence, some in the asbestos industry did the unthinkable-they covered it up. Scientific reports were edited and modified, test results were altered or destroyed, and funding was stopped. The asbestos industry then embarked on a campaign to keep the information from reaching the general public. All the while, manufacturers continued selling millions of dollars worth of asbestos containing products to the public. It was used in massive amounts in shipyards, commercial construction and residential construction. Manufacturers of safer, non-asbestos insulations were bought out by the asbestos industry giants, stifling competition and safeguarding the cover-up.

Through the tireless efforts of some pioneering scientists, the United States government finally realized the hazards of asbestos, and began a slow campaign to curtail, and ultimately prohibit, its use in the United States.

Mesothelioma Law

Litigation is, unfortunately, a required element to secure speedy, just compensation.

For individuals stricken with asbestos related mesothelioma, there may be substantial compensation available if they act quickly to engage an experienced mesothelioma lawyer who is proficient in asbestos legal issues and proving asbestos exposure. Most often mesothelioma lawsuits end up with a settlement without ever going to trial or even into a court. In our experience, this is the preferred scenario for most families with a mesothelioma case.

Since the only known cause of mesothelioma in the United States is asbestos, the key to successful case is proving exposure to the product(s) responsible for the injury. That is why you need to hire an experienced asbestos related disease attorney.

This is not to say that the asbestos industry will simply give away any money. The large corporations that we routinely go up against will hire some of the best attorneys that money can buy to defend and delay against paying compensation to you. This is why retaining an experienced mesothelioma lawyer with a background in this type of case can help you and your family get the asbestos settlement or verdict you deserve.

Coady law firm attorneys have represented many hundreds of clients stricken from asbestos related mesothelioma with compassion, diligence and success. They began their works in mesothelioma case 25 years ago, and they are still hard at it today.

Mesothelioma Symptoms

Symptoms of plueral mesothelioma (lining of the chest cavity) include:

• Cough
• Difficulty sleeping
• Fever
• Pain at the side of the chest or the lower back
• Pleural effusions (fluid in the chest cavity)
• Progressive loss of appetite and weight loss
• Shortness of breath, difficulty breathing
• Tireness
• Trouble swallowing

Symptoms of peritoneal mesothelioma (lining of the abdominal cavity) include:

• Belly Pain
• Nausea
• Vomiting
• Weight loss

If there is reason to suspect you might have mesothelioma, or some other ailment, the doctor will take your medical history and often do a complete physical exam. The exam can help tell if you have fluid in the chest, abdomen, or heart area. This fluid can be a sign of mesothelioma. Then one or more of the methods below can be utilize to determine out if you actually have cancer.

Imaging tests allow the doctor to see a picture of the area in question. These could includex-rays, CT scans (computed tomography), MRI (magnetic resonance imaging), or PET scans.

Fluid or tissue samples may be taken (from the chest, stomach, or heart area) with a needle and sent to the lab to see if cancer cells are present.

Other methods involve making a small cut (incision) in the chest or stomach area and then using a small tube with a video camera to allow the doctor to look directly at the area in question.

In another approach, the doctor can insert a lighted tube through the mouth and into the chest. This is called a bronchoscopy (bron-KOS-kuh-pee). If the tube is placed under the chest bone and then moved down into the chest, it is called a mediastinoscopy (media-stine-AHS-kuh-pee).

Surgery allows the doctor to remove a larger sample of tumor or, sometimes, the whole tumor.

It is often hard to identify mesothelioma by looking only at the cells from the fluid around the lungs, stomach, or heart. So your doctor may want to do other tests as well. Sometimes an electron microscope is used to look at cells in greater detail.

Mesothelioma Treatments

Mesothelioma is a very serious disease and patients and their families should have the support and resources they need to better deal with their diagnosis. The following information should aid patients diagnosed with mesothelioma in determining the best course of treatment:

Traditional Treatments

Surgery

A mesothelioma treatment used either to remove the tumor or to alleviate pain and suffering. If the cancer is relatively contained, surgery can be used to remove part of the lining of the chest or abdomen. The objective is to remove the cancer cells from the body by removing the tissues with large numbers of cancer cells. If the cancer has spread to several organs, it is impossible to remove all of the tissue infected with cancer. In this case, surgery can only be used to relieve pain and suffering. Types of surgeries incude:

Pneumonectomy - An aggressive surgery in which a lung is removed. It can be performed in two ways:

Traditional Pneumonectomy - Only the disease lung is removed.

Extrapleural Pneumonectomy - When the diseased lung, along with part of the pericardium, part of the diaphragm and the parietal pleura on the same side of the chest is removed.

Palliative Procedures - The goal of these procedures is not to cure the disease, but rather to relieve and/or control symptoms associated with mesothelioma:

Thoracentesis - A procedure where a needle is inserted into the chest cavity either to obtain a diagnosis or to drain the fluid to relieve breathlessness and pain.

Pleurectomy/Decortication - The surgical removal of the pleura which is performed to reduce pain caused by tumor mass or to prevent the recurrence of pleural effusion.

Chemotherapy

This treatment consists of using drugs to treat the cancer. The drugs can be swallowed in pill form or can be injected by a needle into a vein or muscle. Most of the drugs used in the treatment of lung cancer either directly kill cancer cells or stop them from dividing into new cells. The drug enters the bloodstream and circulates throughout the body to reach and destroy the cancer cells. Chemotherapy targets the entire body and can kill normal cells as well as the diseased cells, causing severe side effects.

Chemotherapy can be used in combination with a variety of drugs to increase the total effect and is often used in combination with other treatments, especially surgery.

Side effects can be wide ranged and include nausea and vomiting, loss of appetite, loss of hair, fatigue, constipation, coughing, decreased appetite and mouth sores. These side effects can be treated and they will usually cease after the treatment has ended.

Radiation

Radiation therapy is the use of high level radiation to kill cancer cells in a localized area. The radiation injures the cancer cells so they cannot divide or multiply further. With each treatment, more of the cells die and the tumor shrinks. The dead cells are broken down and excreted by the body. Most of the healthy cells are able to recover from this injury, but the damage to them is the cause for the side effects of radiation therapy.

Radiation may be used before surgery to shrink the tumor, after surgery to prevent the cancer from coming back, to prevent the growth of cancer, to treat symptoms, and also in combination with chemotherapy. Radiation therapy is sometimes used as the main treatment of Mesothelioma, especially patients whose general health is too poor to undergo surgery.

Side effects of radiation can be severe. They can include: fatigue, hair loss, skin irritation, nausea, and difficulty breathing.

The process of contacting your doctor in the off office hours needs to be simple and accessible. It should include coverage by a competent oncologist at all times, who can speak with you directly about your medical problem. Most office practices have a doctor on call to take calls from patients 24 hours/day.

Experimental Mesothelioma Treatments

Gene therapy

An experimental medical intervention that involves altering the patient’s genetic material of living cells to fight or prevent disease. The therapy involves injecting a modified gene directly into a patient’s chest cavity. The goal of gene therapy is to supply cells with healthy copies of missing or altered genes. Many different strategies are currently under study.

Immunotherapy

An experimental therapy that uses the body’s natural defenses to fight cancer. This can include stimulating your own immune system to work harder, or using an outside source, such as man-made immune system proteins. Immunotherapy is usually used in conjunction with another type of therapy.

Photodynamic Therapy

An experimental treatment which combines a photosensitizing agent (a drug activated by light) with a light source to destroy cancer cells. The theory is that the photosensitizing agent collects more readily in cancer cells than in normal cells. Thus, when the agent is subsequently exposed to light, it reacts with oxygen to create chemicals that can kill the cancer cells

Asbestos Lung Cancer

Lung cancer, or bronchial carcinoma, occurs in several forms. The most common causes of lung cancer are smoking and asbestos.

Asbestos Related Lung Cancer

This web site has focused on mesothelioma. Not every asbestos-related lung cancer, however, is a mesothelioma. Other thoracic carcinomas, such as adenocarcinoma, are also known to be caused by exposure to asbestos.

The connection between asbestos exposure and lung cancer was noted as early as 1925, and confirmed over the next 70 years by many epidemiologic studies of asbestos-exposed workers. The four main types of commercially used asbestos, chrysotile, amosite, anthophyllite, and mixtures containing crocidolite, have all been associated with an increased risk of lung cancer. About one in seven people who suffer from asbestosis, a lung disease resulting from exposure to asbestos, eventually develop lung cancer.

There is a relationship between cigarette smoking and asbestos exposure in causing lung cancer. Individuals occupationally exposed to asbestos who smoke face a much higher risk than those who do not smoke. According to the National Cancer Institute, evidence suggests that asbestos-exposed workers who quit smoking can reduce their risk of developing lung cancer by 50% within five years of quitting.

Relationships Between Smoking and Lung Cancer

A great deal of attention has been paid to the relationship between smoking and lung cancer. Indeed, many people presume a causal relationship. It is therefore important to understand that while smoking is certainly a potential cause of lung cancer, it is not the sole cause of lung cancer in humans. Statistics have shown that cigarette smoking alone increases the risk of lung cancer by a factor of 10 or so; heavy asbestos exposure alone increases the risk of lung cancer by a factor of 5 or so; and the combination of the two independent carcinogens increases the risk factor by about 50 times.

Thus, you do not merely add the risks posed by asbestos to the risks posed by cigarette smoking. The combination of asbestos and smoking multiplies the risk by an unquantifiable, but significantly greater, factor. This relationship is what is referred to as the “synergistic effect” of smoking and asbestos exposure. In short, one plus one does not equal two-it equals five or more.

What Are The Clinical Signs of Asbestos-Related Lung Cancer?

In general, the clinical features of asbestos-related lung cancer depends upon the state of the tumor when detected. Early detection enhances the prospect of surgical care. Symptoms can include the following:

* Cough
* Chest pain (usually in later stage)
* Difficulty breathing
* Chest x-ray detection of new mass. A tumor may not be visible on a chest x-ray until it is at least 1-0 cm in diameter.
* In its late stages, typical symptoms, signs and syndromes of advanced carcinoma emerge.

Management of an asbestos-related lung cancer depends largely on the staging of the tumor. Early diagnosis and surgical resections of the tumor increase the survival rate. The presence of severe associated asbestosis, however, can affect surgical intervention. Additionally, radiation and chemotherapy may be helpful in the overall therapeutic program

The Asbestos-related cancer deaths

CREWE and Nantwich are reaching a peak in the cases of asbestos-related cancer.
The borough has the highest mortality rate in Cheshire from mesothelioma - a rare type of cancer affecting the lungs largely due to exposure to asbestos, readily used in railway engineering sites such as Crewe Works since the 1940's until it was banned in the UK during the 1980's.

The disease has a latency period and can take up to sixty years to develop which explains the steady rise in mesothelioma deaths in Crewe and Nantwich over the last 20 years.

advertisementThe most recent statistics from the Health and Safety Executive reveal there have been 103 deaths in the borough from the industrial disease from 1985 to 2004, the 16th highest in districts across the UK.
Inquests recently into the deaths earlier this year of Crewe men, 82-year-old Leslie King of Heron Crescent and 90-year-old Leslie Bedson of Eastern Road, both former employees at Crewe Works, revealed they had died from mesothelioma.

"It has been a national epidemic for the last ten years and is about to peak but this should tail off as it is commensurate with asbestos use."
A spokesperson for Mesothelioma UK
Giving evidence, Joseph Chadwick, cousin to Mr Bedson's late wife, said Mr Bedson, a fitter at the railway works all his working life, told how he and his colleagues working nightshifts would sleep on pipes lagged with asbestos, ignorant at the time of the danger.

Mr King, a coppersmith for 49 years, also described in a letter written before his death of being unaware of the dangers involved with the killer dust and the lack of protection offered.
"Asbestos would be all around me, there was a sea of asbestos on the floor and in the air and men would throw it as snowballs," he said.
"Asbestos would fall to the floor and would be walked all round the shop, our overalls would be covered in white asbestos and there would be blue and brown asbestos on the floor.

"We were handling it on almost a daily basis, it was impossible to avoid but we weren't provided with masks until much, much later. No-one insisted we wore them and we were never told of the dangers at the time."
The Coroner for Cheshire Nicholas Rheinberg said he was entirely satisfied that exposure to asbestos led to the development of mesolthelioma in the two men.

A spokesperson for Mesothelioma UK said: "It has been a national epidemic for the last ten years and is about to peak but this should tail off as it is commensurate with asbestos use."
A spokesperson for Bombardier Transport, owners of the former Crewe Works, said: "Since the dangers of asbestos have been known we have introduced high levels of containment at Crewe and it is no longer a problem for our employees."
