Hello and welcome to this article on malignant pleural mesothelioma. This disease is a cancer of the lungs caused by exposure to asbestos. It is a serious condition that requires prompt diagnosis and treatment. In this article, we will provide you with a detailed overview of malignant pleural mesothelioma, its causes, symptoms, diagnosis, treatment, and prognosis. We hope that this article will help you to better understand this disease and its implications. So, without further ado, let’s jump right in!
What is Malignant Pleural Mesothelioma?
Malignant pleural mesothelioma is a type of cancer that affects the lining of the lungs called the pleura. This cancer is caused by exposure to asbestos, a mineral that was widely used in construction, manufacturing, and other industries until the 1970s. Asbestos fibers can be inhaled and become lodged in the lungs, causing inflammation and scarring over time. This can lead to the development of malignant cells, which can spread to other parts of the body if left untreated.
There are three main types of malignant mesothelioma: pleural, peritoneal, and pericardial. Pleural mesothelioma is the most common type, accounting for about 75% of all cases. It affects the lining of the lungs and is often associated with long-term asbestos exposure. Peritoneal mesothelioma affects the lining of the abdomen and is less common, while pericardial mesothelioma affects the heart lining and is very rare.
Causes of Malignant Pleural Mesothelioma
The primary cause of malignant pleural mesothelioma is exposure to asbestos. Asbestos was widely used in construction, shipbuilding, and other industries until the 1970s when its health risks became known. The tiny fibers of asbestos can be inhaled and become lodged in the lungs, causing inflammation and scarring over time. This can lead to the development of malignant cells, which can spread to other parts of the body if left untreated. It is important to note that not everyone who has been exposed to asbestos will develop mesothelioma, and the disease can occur even with short-term exposure.
Other risk factors for malignant pleural mesothelioma include:
- Age: This disease is most commonly diagnosed in people over the age of 65.
- Gender: Men are more likely to develop mesothelioma than women.
- Smoking: Smoking does not cause mesothelioma, but it can increase the risk of developing other lung diseases, which can make the symptoms of mesothelioma worse.
- Radiation: Exposure to high levels of radiation may increase the risk of developing mesothelioma.
- Genetics: Some people may be genetically predisposed to developing mesothelioma.
Symptoms of Malignant Pleural Mesothelioma
The symptoms of malignant pleural mesothelioma may not appear until many years after exposure to asbestos. The early symptoms may be mild and may resemble those of other lung diseases. As the disease progresses, the symptoms become more severe and can include:
- Persistent cough
- Chest pain
- Shortness of breath
- Fatigue
- Weight loss
- Difficulty swallowing
- Fever
- Night sweats
- Swelling of the face and arms
- Hoarseness
- Blood in sputum (phlegm)
Diagnosis of Malignant Pleural Mesothelioma
The diagnosis of malignant pleural mesothelioma involves a number of tests and procedures. These may include:
Physical examination:
The doctor will examine the patient’s chest and listen to their breathing for any sounds that may indicate mesothelioma.
Imaging tests:
These may include X-rays, CT scans, MRI scans, or PET scans. These tests can help to identify any abnormalities or tumors in the chest and determine whether mesothelioma is present.
Biopsy:
A biopsy involves taking a sample of tissue from the affected area and examining it under a microscope. This can help to confirm the presence of mesothelioma and determine the type of cancer.
Treatment of Malignant Pleural Mesothelioma
Treatment for malignant pleural mesothelioma depends on the stage of the cancer, the patient’s overall health, and other factors. The goal of treatment is to remove or destroy the cancer while preserving as much lung function as possible. Treatment options may include:
Surgery:
Surgery may be recommended to remove as much of the cancer as possible. This may involve removing part of the lung or the entire lung, as well as the lining of the chest cavity. In some cases, surgery may be combined with other treatments such as chemotherapy or radiation therapy.
Chemotherapy:
Chemotherapy involves the use of drugs to kill cancer cells. These drugs may be given orally or intravenously, and may be used alone or in combination with surgery or radiation therapy.
Radiation therapy:
Radiation therapy involves the use of high-energy X-rays or other types of radiation to kill cancer cells. This may be used alone or in combination with surgery or chemotherapy.
Prognosis of Malignant Pleural Mesothelioma
The prognosis for malignant pleural mesothelioma depends on a number of factors, including the type of cancer, the stage of the cancer, the patient’s overall health, and other factors. Unfortunately, mesothelioma is often diagnosed at a late stage, making it difficult to treat. The five-year survival rate for mesothelioma is around 10%, but this varies depending on the stage of the cancer and other factors. Early diagnosis and treatment can improve the chances of survival.

| Stage | Description |
|---|---|
| Stage I | The cancer is localized to the lining of the lung and has not spread to other parts of the body. |
| Stage II | The cancer has spread to the lung tissue and nearby lymph nodes. |
| Stage III | The cancer has spread to nearby organs or tissues, such as the diaphragm, heart, or esophagus. |
| Stage IV | The cancer has spread to distant organs or tissues, such as the liver, bones, or brain. |
