Smart Mesothelioma

Malignant Mesothelioma is an aggressive cancer that affects the membrane lining the lungs and stomach, malignant mesothelioma or malignant mesothelioma is the most serious of all asbestos-related diseases. Although rare, mesothelioma cancer is no longer considered rare. The main causes and risk factors for mesothelioma is exposure to asbestos.

mesothelioma has several types and can attack several parts of the body, among other things:

1. Pleural mesothelioma (pleura)
This type is the most common of all mesothelioma. Usually caused by the frequent inhaling asbestos dust fibers, which are then trapped in the pleura and cause scarring and inflammation.

2. Mesothelioma peritoneal (lining of the abdominal cavity)
The second most common type is growing in the peritoneum, the tissue that lines the abdomen. Similar to pleural mesothelioma, the cause is dust and asbestos fibers are either inhaled or find its way into the digestive tract to settle and develop in the lining of the abdominal cavity.

3. Pericardial mesothelioma (the sac that surrounds the heart)
Mesothelioma is ranked as the third most frequently attacks the tissue that lines the heart. The cause is also asbestos, and the cancer develops from abnormal cells that have been developed in the pleura. Somehow the process, but this asbestos dust can break through to the pericardium and develop in the lining of the heart.

4. Mesothelioma of the tunica vaginalis testis (internal lining of the male sex organ) and mesothelioma of the tunica serosa uteri (internal lining of the female sex organs)
Both types of mesothelioma is the most rare. Although uncertain how exactly to asbestos dust can settle and attack the man dna female sex organs, but some cases do show that asbestos dust is the main cause.types of Mesothelioma Cancer

Mesothelioma is a rare and deadly cancer caused by asbestos. While other risk factors can increase the chances of developing mesothelioma, asbestos is the only scientifically proven cause of the disease. 

 

How Asbestos Causes Mesothelioma
Mesothelioma develops in the mesothelium, a thin membrane encompassing the body’s internal organs and cavities. It is caused by exposure to asbestos, often in a workplace environment, though exposure can also take place at home, school, or another location.

In the most common scenario, asbestos fibers are inhaled and eventually become embedded in the lining of the lungs, abdomen, or heart, causing harmful inflammation that eventually leads to the formation of tumors. In some cases, swallowing asbestos fibers could contribute to a type of mesothelioma that forms in the abdomen, known as peritoneal mesothelioma. Asbestos may also travel through the lymph nodes to other parts of the body, such as the pericardium, the mesothelial layer surrounding the heart.

As generally understood by researchers, asbestos can cause DNA damage both directly and indirectly. Directly, asbestos interferes with the mitosis process in cell division, which can cause cellular damage and mutation. Indirectly, asbestos can cause mesothelial cells to release mutagenic reactive oxygen and nitrogen, which also causes mutation.

The process by which asbestos causes mesothelioma can take a very long time. In most cases, it takes anywhere from 10 to 50 years for mesothelioma to develop after the asbestos exposure occurs. However, in a small number of cases, the latency period is much shorter, and there have even been known cases of mesothelioma in children and young teenagers. 

Some Asbestos Types May Cause Mesothelioma More Often 

Asbestos is a generic name for six types of silicate minerals that share common properties. Some studies have shown that certain forms of asbestos may cause mesothelioma at greater rates than others.

One early study, published in 1986, suggested that crocidolite asbestos is about 14 times more potent than other forms of asbestos when it comes to causing both pleural mesothelioma and peritoneal mesothelioma. However, later reviews of the same data indicated that the incidence rate of mesothelioma based on asbestos type was actually much closer.

The most recent consensus among medical professionals is that amphibole asbestos forms – in particular, crocidolite – are more potent than serpentine forms of asbestos, such as chrysotile. Even so, both forms of asbestos are highly carcinogenic. As the Environmental Protection Agency (EPA) has reported, there is no safe level of asbestos exposure, regardless of the type.
 

Other Causes and Contributing Factors
Asbestos is by and large the most significant cause of mesothelioma, with at least 80% of mesothelioma patients having a known history of asbestos exposure (and the rest possibly being exposed without their knowledge). However, studies have shown that there are a few other environmental risk factors that can contribute to a mesothelioma diagnosis.
 

Asbestos-Like Minerals
Asbestos is a class of silicate minerals, and other silicate minerals have been linked to mesothelioma. Erionite, a form of zeolite, in particular has been associated with the disease, based primarily on a study of the mineral where it occurs naturally in Cappadocia, Turkey. 

Simian Virus 40 (SV40) 

One study showed that in more than half of mesothelioma cases, the patient was also infected with SV40. Further research has indicated that SV40 may contribute to the development of mesothelioma, though it does not appear to cause mesothelioma on its own.
 

Smoking
Smoking itself is not a cause of mesothelioma. However, individuals who smoke and who are exposed to asbestos have a much higher risk of developing asbestos-caused lung cancer (a different malignancy than mesothelioma). 

Radiation Exposure
In a handful of cases, mesothelioma patients have claimed their cancer was caused by radiation exposure, rather than asbestos exposure. While radiation has been linked to the development of some cancers, the link between radiation and mesothelioma is yet to be confirmed. 

Carbon Nanotubes
A few studies have looked at carbon nanotubes, and other high aspect ratio nanoparticles (HARNs), as potential causes of mesothelioma. However, additional studies need to be completed to look at different lengths, shapes, and other factors before attributing these to be causes of mesothelioma.

What Are The Causes Mesothelioma

The mesothelium is a membrane that covers and protects most of your internal organs. It is made up of 2 layers. The inner layer wraps around different organs, including the lungs, heart and stomach. The outer layer forms a sac around the inner layer. There is a small amount of fluid between the 2 layers so that the organs can move easily.

The mesothelium has different names, depending on where it is in the body. The mesothelium that protects and cushions the lungs is called the pleura. The inner layer that covers the lungs is called the visceral pleura. The outer layer that lines the inside wall of the chest is called the parietal pleura.
The mesothelium that covers the abdominal organs and lines the walls of the abdomen and pelvis is called the peritoneum. The inner layer is called the visceral peritoneum. It covers and supports most of the internal abdominal organs. The outer layer is called the parietal peritoneum. It lines the wall of the abdomen and pelvis.

The mesothelium is made up of mesothelial cells. These cells sometimes change and no longer grow or behave normally. These changes may lead to non-cancerous, or benign, tumours such as fibrous tumour of the pleura and multicystic mesothelioma. But in some cases, changes to the mesothelial cells can cause malignant mesothelioma.

Mesothelioma is a very rare type of cancer. It most often develops in the pleura, which is called pleural mesothelioma. This type of cancer makes up 70%–80% of all mesotheliomas. Cancer can also start in the peritoneum, which is called peritoneal mesothelioma. This type of cancer makes up about 25% of all mesotheliomas.

Rarer types of mesothelioma can also develop. These include pericardial mesothelioma, which starts in the membrane that surrounds the heart. Another rare type is mesothelioma of the tunica vaginalis testis, which starts in the outer lining of the testicle.what is mesothelioma , causes mesothelioma , pragnosis mesothelioma
