Epithelial mesothelioma is the most common within the cancers
A way in which experts in mesothelioma can describe in greater depth this disease is to examine the type of tumor and structure of their cells. While it is more common for doctors classify cancer based on its location on the body, there are also several subtypes of pleural mesothelioma, peritoneal, pericardial and testicular.
With studies of the anatomy cell, also known as histology, researchers have been able to identify the characteristics of cells in a tumor affected by mesothelioma and so determine to which subtype of mesothelioma belongs. With this information, you can predict a little better the progression of the disease in the patient, life expectancy and likely to respond to the treatments applied.
There is a large number of types of mesothelioma at the cellular level, however the three most common are the epithelial, sarcomatoid and biphasic.
Is accounting for between 50% and 70% of all cases, mesothelioma epithelial is the most common within the cancers present in this category. Compared with other types of cell, this responds best to treatment and consequently, that offers more prognosis of life.
Is the least common within the types of mesothelioma in this category affecting between 10% and 20% of the patients. This type of cancer is very aggressive and the expectation of life is quite short. The most recent study that was conducted showed that on average, a patient affected with this type of cancer has an average life span of three and a half months.
Is a combination of epithelial?mesothelioma ?and sarcomatoid cancer mesothelioma biphase affects a between a 20 and 35% of the patients. By the fact that the proportion of epithelial cells to cells biphasic can vary significantly, the distribution of cells influence the life expectancy of the patient. A large number of epithelial cells represents a prognosis of life quite favorable.
Malignant Mesothelioma vs. mesothelioma benign
Most of the tumors are malignant, this means that the disease is carcinogenic and has the ability to spread to other parts of the body. However, not all tumors are malignant. Some of the tumors of mesothelioma are benign and non-carcinogenic. These tumors are characterized by grow slowly and does not metastasize in systemic organs.
The mesothelioma benign normally develops in the peritoneum of the patients without a history of any exposure to asbestos. While the majority of patients are young and middle-aged women, have been diagnosed with mesothelioma cases benign in adult men. The majority of the patients did not show any symptoms, however, complications can occur if a tumor grows too. The 20 percent of patients with tumors of mesothelioma benign larger than 7 centimeters in size may have pain in the bones and joints, sugar levels low and attacks of epilepsy.
