How much asbestos exposure does it take to get mesothelioma?
An exposure of as little as one or two months can result in mesothelioma 30 or 40 years later and in some cases, as much as 70 years later.

How long does it take after asbestos exposure for mesothelioma to show up?
People exposed in the 1940s, '50s, '60s, and '70s are now being diagnosed with mesothelioma because of the long latency period of asbestos disease.

How is mesothelioma diagnosed?
Mesothelioma is diagnosed by pathological examination from a biopsy. Tissue is removed, placed under the microscope, and a pathologist makes a definitive diagnosis and issues a pathology report. This is the end of a process that usually begins with symptoms that send most people to the doctor: a fluid buildup around the lungs (pleural effusions), shortness of breath, pain in the chest, or pain or swelling in the abdomen. The doctor may order an X-ray or CT scan of the chest or abdomen. If further examination is warranted, the following tests may be done:
ThoracoscopyFor pleural mesothelioma, the doctor may look inside the chest cavity with a special instrument called a thoracoscope. A cut will be made through the chest wall and the thoracoscope will be put into the chest between two ribs. This test is usually done in a hospital using a local anesthetic or painkiller.If fluid has collected in your chest, your doctor may drain the fluid out of your body by putting a needle into your chest and using gentle suction to remove the fluid. This is called thoracentesis.
PeritoneoscopyFor peritoneal mesothelioma, the doctor may also look inside the abdomen with a special tool called a peritoneoscope. The peritoneoscope is put into an opening made in the abdomen. This test is usually done in the hospital under a local anesthetic.If fluid has collected in your abdomen, your doctor may drain the fluid out of your body by putting a needle into your abdomen and using gentle suction to remove the fluid. This process is called paracentesis.
BiopsyIf abnormal tissue is found, the doctor will need to cut out a small piece and have it looked at under a microscope. This is usually done during the thoracoscopy or peritoneoscopy, but can be done during surgery.Unfortunately, in some cases, tumor cells can grow along the tract where the biopsy is taken. This can be minimized with the use of radiation to the area.

What causes mesothelioma?

What causes mesothelioma?
Most people with malignant mesothelioma have worked on jobs where they breathed asbestos. Usually, this involves men over 40 years of age. Others have been exposed to asbestos in a household environment, often without knowing it. Interestingly, the number of new cases of mesothelioma has been relatively stable since 1983, the same time that the restrictions on asbestos were instituted by the U.S. Occupational Safety and Health Administration (OSHA). In Europe, the number of new cases of mesothelioma continues to rise.

What are the symptoms of mesothelioma?

What are the symptoms of mesothelioma?
Most people present with complaints of shortness of breath. They also can have complaints of chest pain. Surprisingly, this pain is often not pleuritic; that is, it does not get worse with deep breathing. This is surprising in that the pleura (outer surface of the lung) is often involved in this disease, and most other diseases involving the pleura are often associated with pleuritic pain (pain that worsens with deep breathing). Patients may also be asymptomatic, with the disease discovered by physical exam or an abnormal chest X-ray.
As the disease progresses, shortness of breath increases, and weight loss, decreased appetite, and night sweats can develop. Local invasion by the tumor can result in changing of voice, loss of function of the diaphragm, and symptoms specific to the area and involvement of adjacent structures.

What is mesothelioma?

Mesothelioma is a form of cancer affecting the abdominal cavity, chest cavity, and the region surrounding the heart. Due to its uncommon nature, mesothelioma is typically difficult to diagnose and treat. It has been connected with exposure to asbestos, a material formerly present in many work environments. Only about 3,000 individuals are diagnosed annually.
Individuals with a history of extended asbestos exposure are at the highest risk for developing malignant mesothelioma. Even a small exposure to this cancer-causing material can result in malignant mesothelioma. However, mesothelioma has a latency of up to thirty-forty years, and many individuals previously exposed to asbestos are now displaying symptoms. This means the average age of mesothelioma patients is between 50 and 70 years. Men are typically affected more, due to the common presence of asbestos in industrial settings. There are three major types of malignant mesothelioma . epithelial, sarcomatoid, and mixed. Epithelial mesothelioma is most common. Symptoms may include, but are not limited to respiratory distress, a lasting cough, and pneumonia. In addition, symptoms are often mistaken for less serious ailments, and many patients do not show any signs at all.
Individuals with pleural mesothelioma may accumulate some fluid between the lung lining and chest cavity. This can be detected through a chest x-ray, as well as CT scans.
Diagnosis of Mesothelioma is based on a pathological exam, more commonly referred to as a biopsy. This exam will test a tissue sample for the presence of malignant and/or pleural mesothelioma.

Asbestos as the Primary Cause of Mesothelioma

Asbestos is a type of insulation material, which was used widely in the past in the following industries:
Construction industry
Ship building industry
Automotive industry
Other manufacturing industries
Mesothelioma occurred most often in persons who worked in the above industries and were exposed to asbestos in their workplace. The use of asbestos was very widespread after 1945. However, first symptoms of mesothelioma may not become apparent 10-40 years after the initial exposure, which makes it very hard to diagnose. The peak in mesothelioma cases is expected to be reached around 2010 according to some studies. There are three most commonly used types of asbestos: white, brown, and blue. Brown and blue asbestos are most commonly associated with mesothelioma. These types of asbestos have been banned by most countries in the 1990s.
Asbestos is a very dangerous substance and can cause a lot of damage to your health. It is made up of very small fibers, which can find their way to pleura (outside lining of the lung) and damage the cells pleura is made of. These fibers can also be carried on clothing, which makes them dangerous not only to the person exposed to asbestos, but to their family members as well.


Note of Urgency

Mesothelioma is a life-threatening disease and cannot be left untreated. The sooner it is diagnosed the better a patient's chances are of fighting this deadly cancer. Please contact a qualified physician immediately if you or someone you know has been diagnosed with mesothelioma.
