Mesothelioma overview

Mesothelioma is a dreaded cancer that is nearly always caused by just one factor: exposure to asbestos.

Causes of Mesothelioma

Before the grave dangers of asbestos were known, and even for years after the dangers were known, asbestos was used in literally thousands of products that humans and animals encounter every day - particularly in building components such as ceiling and floor tiles, walls, bricks and stucco, and in automotive parts such as brakes and clutches.

People who worked in the asbestos industry or in fields in which asbestos is used as a component of a product are most at risk for mesothelioma. Many individuals who have mesothelioma labored for years or even decades in jobs that required frequent contact with asbestos. When this mineral is mined, processed, woven, sprayed or otherwise manipulated, its microscopic fibers can be released into the air, where they may be inhaled, initiating the development of mesothelioma.

Types of Mesothelioma

Mesothelioma can attack the pleural lining around the lungs. It can also attack the peritoneum, a tissue that surrounds the GI tract. Mesothelioma can attack the stomach lining, other internal organs, or even the pericardium (the tissue sac covering the heart). Thus, mesothelioma can be generally classified into the following types:

  • Pleural - 75% of all mesothelioma cases
  • Peritoneal - 10%-20%
  • Pericardial - 5%

Mesothelioma can also be classified by the cancer type rather than the location of the cancer:

  • Epithelioid - most common, best survival rate
  • Sarcomatoid - most severe, but more rare
  • Mixed/biphasic - a mixture of epithelioid and sarcomatoid cancer

  2. Mesothelioma
    patients undergoing treatment should follow a special
    cancer diet devised by their nutritionists. Cancer diets involve
    eating the correct amounts of protein and calories as well as drinking
    the right amount of water to keep the ailing body replenished and
    energized. The body needs plenty of nourishment when it is going
    through chemotherapy or even when the patient is taking certain
    medications.
    As with most cancers, along side traditional treatment changing your
    diet can help. Increase soy beans products in your diet, the alpha
    carotene and lycopene in soy help to revert and reduce tumor growth
    and metastasis. Other anti-cancer foods that should be plentiful in
    your diet are cabbage, kale, Brussels sprouts, shiitake mushrooms,
    broccoli, pears, citrus fruits, turmeric, tomatoes, blackberries,
    raspberries, blueberries, green tea, walnuts, spinach, wheat bran,
    rice bran, rosemary, garlic, thyme, oregano and onions. These foods
    should be organic. Cut down on meat (especially grilled or barbecued)
    and dairy food consumption, pickled food, smoked food, alcohol,
    saturated fats, salt, sun exposure and smoking.

How does mesothelioma kill you?

It will kill you like any other cancer- cancer cachexia, infections, etc In addition it can compromise your respiratory functions (not enough lung tissue for your routine breathing) If it involves major portion of lung that can add strain on your right heart which can fail(called cor pulmonale)

Mesothelioma Treatment

Treatment of  Mesothelioma Treatment of malignant mesothelioma using conventional therapies has not proved successful and patients have a median survival time of 6 - 12 months after presentationcitation needed. The clinical behaviour of the malignancy is affected by several factors including the continuous mesothelial surface of the pleural cavity which favours local metastasis via exfoliated cells, invasion to underlying tissue and other organs within the pleural cavity, and the extremely long latency period between asbestos exposure and development of the disease. Surgery Surgery, either by itself or used in combination with pre- and post-operative adjuvant therapies, has proved disappointing. A pleurectomy/decortication is the most common surgery, in which the lining of the chest is removed. Less common is an extrapleural pneumonectomy (EPP), in which the lung, lining of the inside of the chest, the hemi-diaphragm and the pericardium are removed. Radiation For patients with localize...
