Mesothelioma - Gain The Cancer Facts To Become Aware Of

By Francisco Rodriguez


Diagnosis Confirming if Mesothelioma is present is done through a biopsy, performed by an oncologist or even a doctor specializing in the diagnosis and treatment of cancer pathologies, removes a small sample of tissue from a patient and examines it using a microscope. Difficulty breathing, abdominal and chest pain, and fever can all be attributed to other causes, so this cancer can have the time to advance fairly well before diagnosis of the disease. Because of the difficulty in diagnosing mesothelioma, the survival time after diagnosis is estimated at about one year. The time that occurs between exposure and the start of the disease, and the rate at which it progresses, makes diagnosis extremely difficult. Early diagnosis is thus crucial in treating this particular form of cancer.

Asbestos cancer most often develops in men between the ages of 50 to 70 years who were exposed to high levels of asbestos in the workplace. Asbestos was mainly used in manufacturing industries such as automotive and ship building as well as in the construction industry. The use of asbestos was only recently banned in the 1990's.

Cause If this chemical is inhaled, it can be extremely toxic and thus cause this type of cancer. As asbestos fibers are released into the air they can be inhaled or digested which can cause the cancer. When asbestos fibres accumulate in the peritoneum (which is the lining of the abdomen) this can lead to peritoneal mesothelioma and the building up of fibres around the tissue of the heart causing pericardial mesothelioma. If asbestos fibres accumulate in the lining of the lungs this can result in cells nearby becoming deformed eventually resulting in what is called pleural mesothelioma.

Pleural mesothelioma is a rare disease which attacks the lining of the lung and chest cavity and is usually cancerous, caused as a result of asbestos exposure and it could take 15 to 35 years to develop the disease, from the time of the asbestos exposure. Smoking does not cause it. The only known, established cause of Mesothelioma is asbestos. To repeat, the primary cause of mesothelioma cancer is linked to exposure to asbestos fibers which are breathed into the lungs or swallowed.

Immunotherapy: This form of biological therapy for mesothelioma cancer treatment uses the patient's own immune system to attack the cancerous cells. Clinical studies have shown that the immune system is able to distinguish healthy cells from cancer cells, and can therefore be used to destroy those cancerous cells. Gene Therapy: This form of mesothelioma cancer treatment is very much still in the developmental stages. The process involves injecting a specific gene straight into the tumour. This gene renders the cancer cells sensitive to the antiviral drug glanciclovir which under normal circumstances is not effective against these cells. The glanciclovir is then able to destroy all the cancer cells without harming the healthy tissue cells.

Drug Therapy: The drug Alimta is the only chemotherapy drug to be approved by the Food and Drug Administration (FDA)for the treatment of patients with malignant mesothelioma lung cancer . This new and exciting drug has been demonstrated in clinical trials to reduce symptoms and increase the life expectancy of patients. Photodynamic Therapy: Photodynamic therapy involves the use of light to destroy cancer cells. The patient first is first administered a photosensitizing drug that only collects in cancerous cells. Fibre-optic cables are then inserted in the body in order to focus light of a certain frequency on the tumour. The light stimulates the photosensitizing drug to produce toxic oxygen molecules that destroy the cancerous cells.

As mentioned before, the type of mesothelioma has an impact on the prognosis, including the age of the patient, how much the tumor has actually developed and if treatment was given.
