What is malignantpleural mesothelioma
Malignant pleural mesothelioma is a tumor that arises from a thin layer of tissue that covers many internal organs.
Known as the mesothelium, the area most affected is the lining of the lungs and chest wall, and less commonly in the serous membrane of the abdomen. The pericardium is rarely affected. A tumor takes many years for a patient to develop symptoms.
The period may reach between 20-40 years after inhaling asbestos dust, which is the number one cause of malignant pleural mesothelioma, and there are genetic reasons in which a study was conducted on people who have a mutation in the gene (BAB1), and they are at the highest risk of developing mesothelioma and skin cancer.
What are the early warning signs ofmalignant pleural mesothelioma?
The first signs that a patient with malignant mesothelioma may appear are severe coughing, difficulty breathing, pain during breathing due to fluid buildup around the lung, as well as pain and swelling in the abdomen, feeling tired and unexplained weight loss. .
Hoarseness and voice change Anemia symptoms usually appear gradually, and more than 80% of malignant pleural mesothelioma cases are caused by exposure to asbestos, and the higher the exposure the higher the risk.
In severe cases of malignant pleural mesothelioma, some of the following signs and symptoms may appear:
- Jaundice and yellowing of the eyes and skin
- low blood sugar
- pleural effusion
- pulmonary embolism
- severe ascites
How is malignant pleural mesothelioma diagnosed and detected?
- Positron emission tomography to identify dysfunction in organs and tissues
- Ultrasound bronchoscopy to obtain images of the lungs and surrounding areas to detect the presence of any tumors
- Pulmonary function tests to monitor breathing and assess lung function
- Sputum cytology is a microscopic examination of cells from a sample of lung mucus
- Bronchoscopy to examine the airways of the lungs
- Aspiration of a needle through the chest to take a sample of lung tissue for examination under a microscope
How does a person get mesothelioma?
Malignant pleural mesothelioma by exposure to asbestos In most but not all cases, many patients exposed to asbestos also have areas of abnormally thickened pleura called pleura plaques. Dense layers of collagen can be like cloning cells.
There are three types ofMalignant pleural mesothelioma
- Mesothelioma is oval to cubic
- Sarcomatoid mesothelioma
- biphasic mesothelioma
Your pathologist should see at least 10% of each cell type in the tissue samples examined under a microscope.
Malignant mesothelioma often appears in adults over the age of fifty, but the incubation period of malignantpleural mesothelioma is very long and exceeds twenty years, meaning that at least twenty years may pass from the moment of exposure to the causative factors to the onset of the disease. The formation of malignant pleural mesothelioma and the appearance of its symptoms,Young people may develop mesothelioma if they are exposed to asbestos during childhood
