ASBESTOS CANCER (MESOTHELIOMA) & ASBESTOSIS

Information from Medic8® Family Health Guide here

Asbestosis

Asbestosis is a non-cancerous, chronic lung illness caused by exposure to asbestos.

Significant exposure to asbestos increases the risk of lung cancer, mesothelioma and non-malignant lung and pleural disorders.

Risk depends on duration, frequency, concentration, & type of asbestos fibres.

Diseases from asbestos exposure take a long time to develop. Most cases of asbestosis occur in asbestos workers 15 or more years after initial exposure to asbestos.

Smoking greatly increases the likelihood of lung cancer in workers exposed to asbestos (although smoking does not appear to increase the risk of mesothelioma).

Mesothelioma (asbestos cancer)

Mesothelioma is a rare cancer which may affect the lining of the lungs (pleura) and the abdominal cavity (peritoneum).

Most mesotheliomas are caused by exposure to asbestos.

Most cases of mesothelioma are diagnosed 30 years or more after the first exposure to asbestos.

Mesothelioma occurs more often in men than in women.

Risk increases with age.

Symptoms & Signs

Shortness of breath (this is the primary symptom)

A persistent and productive cough

Chest tightness

Chest pain

Loss of appetite/weight loss

A crackling sound in the lungs while inhaling.

Diagnosis

History of asbestos exposure.

Chest X-rays are the most common method of detecting asbestos-related disorders.

Other tests:

Physical Examination
Pulmonary Function Tests
Biiopsy/Bronchoscopy
CT scan

Treatment

Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient's age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined.

Getting Help

Only a doctor can make the diagnosis of mesothelioma. It is important to see a doctor if you have been exposed to asbestos and have any symptoms.

What is Mesothelioma?

Article from wikipedia here:

Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the pericardium (a sac that surrounds the heart) or tunica vaginalis.

Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways. Washing the clothes of a family member who worked with asbestos can be all that it takes. Unlike lung cancer, there is no association between mesothelioma and smoking.^[1] Compensation via asbestos funds or lawsuits is an important issue in mesothelioma (see asbestos and the law).

The symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and general symptoms such as weight loss. The diagnosis may be suspected with chest X-ray and CT scan, and is confirmed with a biopsy (tissue sample) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to take biopsies. It allows the introduction of substances such as talc to obliterate the pleural space (called pleurodesis), which prevents more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.
