Pleural Mesothelioma is a rare malignant cancer caused by inhalation of asbestos fibers in the lungs. Nearly 75% of cases of mesothelioma are formed in the pleura, making it the most common of the four types.
Pleural Mesothelioma is cancer that develops in the cells that make up the outer wall of the lungs and the inner lining of the chest cavities. It is the most common type of cancer associated with asbestos. Clinical trials offer access to new treatments such as immunotherapy. All types of mesothelioma are called where they are formed.
Mesothelioma usually lasts between 20 and 50 years after the first exposure to asbestos. Due to this delay period, the disease usually affects people over the age of 75 years.
The majority of patients are men because they represent the bulk of the workforce in professions, including heavy industry and construction, where asbestos exposure has traditionally been observed.
The first symptoms of malignant pleural mesothelioma include chest pain and shortness of breath. You may not show symptoms early in the progression of cancer.
The life expectancy of a person with mesothelioma of the pleura is usually less than 18 months, but it depends on many factors.
Some patients live much longer with treatment. The combination of several therapies, such as surgery, chemotherapy, and radiotherapy, has allowed people to live for years after the diagnosis of pleural mesothelioma. Clinical trials offer access to new treatments such as immunotherapy.
How does asbestos cause pleural mesothelioma?
Asbestos causes malignant pleural mesothelioma for decades after a person inhales the asbestos dust. Needle-shaped needles of the mineral residue in the lungs and progressively migrate to the mucous membrane of the pleura.
Plaque that is formed in the lateral mucosa of the lungs.
For a long time, asbestos fibers cause irritation, chronic inflammation and genetic changes that make the cells cancerous.
These cancer cells grow rapidly and uncontrollably, threatening the surrounding organs.
Two layers are the lining of the pleura. The outer layer covers the entire inside of the chest cavity and the inner layer covers the lungs.
A malignant tumor can develop into one or other layer and spread rapidly to the other layer. When tumors develop on the surface of the pleura, they grow to form a mass around the affected lung.
