Lung Cancer Mesothelioma: Slowly Spreading Its Tentacles

Lung cancer mesothelioma is the common name for malignant
mesothelioma, a rare cancer that is not very responsive to
therapy. Lung cancer mesothelioma is the deadliest of all
asbestos related diseases. Medically speaking, lung cancer
mesothelioma is misnomer. Mesothelioma is not a cancer of the
lungs; it generally affects the lining of the lungs.

Mesothelial cells are special cells found in cavities of certain
internal organs. They form a covering tissue surrounding most of
the vital organs. This tissue is known as pleura, peritoneum and
pericardium and surrounds lungs, abdomen and heart respectively.
This tissue produces a lubricant that allows the internal organs
to move effectively. For example, it helps the lungs to move
around in the chest during breathing. Lung cancer mesothelioma
is the name given to cancer of the lining of the lungs. It is
the most common of mesothelioma cancers and is known as pleural
mesothelioma.

Mesothelium tumors can be cancerous as well as non-cancerous.
However, most mesothelial tumors are cancerous. The malignant
mesothelioma referred to as "mesothelioma". About 75%
mesothelioma tumors start in the chest cavity (pleural
mesothelioma). About 10% to 20% occur in the abdomen (peritoneal
mesothelioma). Pericardial mesothelioma is a rare disease and
even rare is the incidence of mesothelioma in the lining
surrounding the testicles.

Mesothelioma cancer was first recognized as a tumor of the
pleura, peritoneum and pericardium in the late 1700s. It was
only in the 1960s that could this tumor be connected to exposure
to asbestos and be described with detail. The first person to do
so was J. C. Wagner, who cited examples from the "Asbestos
Hills" in South Africa and provided sufficient evidences to
establish a link to mesothelioma cancer of the lung cavity to
asbestos exposure. Further studies have confirmed the
relationship between asbestos and the incidences of mesothelioma
cancers.

Mesothelioma cancers were a rarity in the United States. There
were only 14 cases recorded per million people in a year.
However, the number has tripled between 1970 and 1984
particularly among the males working in areas of asbestos
production and shipbuilding facilities. Mesothelioma cancers are
Mostly found in sexagenarian males and in some cases, it has
also been discovered in women and children.
