What’s a pleural mesothelioma? Is it cancer?
Mesothelioma is a relatively rare but highly hazardous disease that originates in mesothelioma cells. The pleural membrane is a thin membrane that covers the surface of the lung and the inner walls of the pleural cavity and plays an important role in maintaining normal respiratory function and the stability of the environment within the pleural cavity.
Mesothelioma in the pleural mesothelioma is divided into two main types of limitations and permeability in terms of pathology. Restrictive mesothelioma is usually benign or low-intensity, growing relatively slowly and often in the form of local pleural swelling. Pervasive mesothelioma is highly malignant and rapidly and dangerous.
On the question of whether mesothelioma is a cancer, in medical terms cancer is generally referred to as malignant tumours originating from the upper skin. While pleural mesothelioma does not originate in the upper skin tissues, pleural mesothelioma is often treated and treated as cancer in clinical practice because of its highly malignant and invasive characteristics.
The causes of mesothelioma are closely related to asbestos exposure. In the occupational environment, there is a significant increase in the risk of mesothelioma among people exposed to asbestos fibres for long periods of time. Asbestos fibres can enter the human body through the respiratory tract and are deposited in areas such as the pleural membrane, which, after long periods of irritation and damage, results in a pleural mesotheliation. Moreover, asbestos exposure to disease tends to have a long incubation period, possibly up to 20 – 40 years.
In addition to asbestos exposure, there are other possible pathogenic factors such as Apevirus 40 (SV40) infection, radiation, etc., but their mechanisms and evidence of impact are currently being further studied.
The clinical performance of mesothelioma is diverse. At an early stage, patients may have only non-specific symptoms, such as chest pain and respiratory difficulties, which can easily be misdiagnosed as other respiratory diseases. As the condition evolves, chest pain increases, which may be persistent blunt pain or sting. Respiratory difficulties are also exacerbated by the continuous growth of the tumours on the pleural membranes, the intrusion of the lung tissue and the disruption of normal respiratory functions, as well as the potential for large amounts of saping fluids in the chest cavity to further pressure the lung tissue.
In the area of diagnosis, visual examinations such as chest X-rays, CTs, etc. can reveal unusual conditions such as pleural increase, knots or chest cavity fluids. The diagnosis, however, often requires a pathological examination of the pathological tissue through a pleural lens examination or a pleural biopsy to determine the type and nature of the tumor.
Treatment of mesothelioma is a very challenging task. For restricted pleural mesothelioma, the patient has a relatively good prognosis if early detection and complete tumour removal is possible. However, in the case of permeable pleural mesothelioma, due to extensive tumour intrusions and the surrounding tissue, surgical removal is often difficult to complete and requires a combination of treatments.
Surgery can reduce the tumour load by removing the tumour tissue visible to the naked eye as far as possible. chemotherapy is also one of the most important treatments, and commonly used chemotherapy drugs, such as peptosis, can inhibit the growth and spread of tumour cells. Treatment can also be used in some cases to mitigate local symptoms and to control tumour progression.
The prognosis of pleural mesothelioma is generally poor, especially in the case of pleural mesothelioma. However, with further medical research, new diagnostic techniques and treatments are emerging, such as new treatments such as immunotherapy, which offer new hope for mesothelioma patients. Raising awareness and vigilance about the disease is crucial for early diagnosis and for improving patient prognosis, especially for populations with high-risk factors such as the history of exposure to asbestos, and for increased attention and regular screening.
