Mesothelioma is a cancer. It happens in people that came into contact with asbestos. It commonly damages the lungs and abdomen. No other inner organs are comprised into the roll of possible attacked. Nowadays there is no efficient mesothelioma treatment option. There are some various mesothelioma cure variants, such as chemotherapeutics and radiation therapy or surgery. All the people that asked for assistance, as it turned out, have been working with asbestos for over 20 years. Taking it into account we can see that the job regarded to any processes with asbestos is quite dangerous. The fluids in lungs are the cause of frequent pangs in the chest if the patient suffers from the malignant mesothelioma cancer. Such kind of mesothelioma as peritoneal one may produce the loss of weight, blood clotting and some problems with swallowing. That is quite hard to detect the not innocent mesothelioma, because its symptoms are very similar to other diseases. At first the physicians who is executing the examination should carefully study the medical history of the patient. If includes the exposure to asbestos, there are more chances to reveal the mesothelioma. Almost all such persons further are being examined by an oncologist. The oncological inspection should be executed by means of X-ray scans, but finally the person will be diagnosed only after the biopsy. But the new method of resolving this problem was designed recently. The Mesomark testing method consists of special devices which will inspect the degreens of proteins from cells that are suspicious to be damaged by malignant tumor. It can reveal much earlier that already existed methods. All the illnesses are not so hard to cure on its initial stage. Such form of malignant neoplasm as mesothelioma is quite complicated. Conventional systems permit the person to survive up to a year, on average after the cure has been administered. For instance, mesothelioma surgery even when used together with other treatments has been producing mostly negative results. Mesothelioma cannot be completely cured using the surgery method. The malignant neoplasm cannot be removed completely because the patient can die. The malign mesothelioma may be treated by means of radiation therapy. It commonly mixed with radical surgery and provided at the same time with chemotherapeutics. This combination has permitted achieving longer survival in selected persons. However, when given alone, without other treatment option, radiation therapy does not extend patients' life expectancy. If the surgery was not used that needed dose of radiation would exceed all the limits and can kill the person. Chemotherapy stipulates giving the person drugs that inhibit formation of malignant tumor cells. Those preparations influence on the healthy cells so they could be consumed only in combination with the special preparations which reduce their side effects. To cure malign mesothelioma doctors use pemetrex in combination with cisplatin. Unfortunately, modern medicine is able to sustain only a limited span of life with some malignant mesothelioma.
