What is Malignant Mesothelioma ??


It is a type of cancer which actually starts in cells in the linings of some of the certain body parts especially the chest linings & the abdomen linings of the body.

This Malignant Mesothelioma Cancer starts when the cells starts to grow out of control in enormous amount in the body. This Uncontrollable enormous growth of cells will be at any part of the body. If you wanna know about the what actually cancer means , Read : What is Cancer ??

Malignant Pleural Mesothelioma & Biphasic Mesothelioma & Benign Mesothelioma is also common like mesothelioma these days . Just some medical attention is required from the medical experts i mean doctors. Know more about the mesothelioma from the below marked words.

The Mesothelium – Mesotheliomas :


A specialized cells which are in a layer is called Mesothelial Cells . These Mesothelial Cells lines inside the chest , the space around the Chest & Heart . These cells lines mainly inside the abdomen , covers outer surface of our internal organs too . The lining formed by the Mesothelial Cells is called Mesothelium.

what is malignant mesotheliomaThis mesothelium helps to protect your organs just by making a special lubricating fluid which allows the organs in order to move against each others. For example, if the fluid makes easier for your lungs to move (i mean expanding and contracting) inside the chest cavity when you breathe(exhale & inhale). This mesothelium has some different names based on affecting of desease at different parts of the body:

  • The pleura coats lungs and the space in the chest which is containing the lungs.
  • The peritoneum lines inside the abdomen and also many other parts of the organs which are in the abdomen.
  • The pericardium that covers the heart and also creates the space that’s the thing holds the heart in the chest.
  • The tunica vaginalis will lines the testicles.

The Mesothelial tumors starts in any of those linings which listed above. All these Mesothelial tumors can be non-cancerous tumours (benign) or the cancerous (malignant) tumours.

Malignant mesothelioma

Malignant Mesothelioma is a cancerous tumor of the mesothelium , although this thing is often shortened to just mesothelioma but real name is malignant mesothelioma . Mesothelioma can start in any 4 main areas of the body.

  • Pleural mesothelioma starts in the chest. About 3 mesotheliomas are pleural mesotheliomas among 4 mesotheliomas.
  • Peritoneal mesotheliomas begins in the abdomen. They makes up most of all the remaining cases.
  • Pericardial mesotheliomas starts around the heart in the covering and These are very rare.
  • Mesotheliomas of the tunica vaginalis are actually very rare that starts in covering layer of the testicles. Normally this mesotheliomas affection is very rare to many.

These Malignant mesotheliomas are also classified into 3 main different types based on arrangement of cancer cells:malignant pleural mesothelioma

  • About half of all mesotheliomas are epithelioid. That means this type tends to have better outlook (prognosis) than all other types of mesotheliomas .
  • But about 10% are sarcomatoid (fibrous) of all mesotheliomas.
  • Other Mixed (biphasic)  have both the epithelioid and the sarcomatoid areas of mesothelial cells . Those makes up the remaining 30% – 40% mesotheliomas.

Benign tumors of the mesothelium (Lining of Mesothelial Cells) :


The non-cancerous tumors (benign tumours) can also starts in the mesothelium. These benign tumors easily removed by surgery these days and there is no need of additional treatment for this type of mesothelium cancer.

Localized fibrous tumor of the pleura – Mesothelial Cells – Mesothelioma Incidence :

This benign tumor can form in any portion of pleura which is actually surrounded to the lungs. It is also called as ” benign fibrous mesothelioma, but now the doctors know that this benign tumor actually doesn’t start in mesothelial cells. This disease is benign, but only 1 in 10 are cancerous , mostly non-cancerous. If the similar thing happens in peritoneum then it is called as ” solitary fibrous tumor of the peritoneum.

Adenomatoid mesothelioma – Pleural Plaques – Mesothelioma Help :

This type of benign tumor can develop in mesothelium of certain reproductive systems/organs. In men, it is common in epididymis ( i mean the ducts that carry the sperm cells out of the testicles ). But in women, this benign tumor begins in the fallopian tubes ( i mean the tubes that carry the eggs from ovaries to the uterus ).

Benign cystic mesothelioma – malignant pleural mesotheliomapleural plaques :

This is rare & non-cancerous tumor which often begins in peritoneum of the body.
