Hello and welcome to this journal article on the symptoms of mesothelioma. Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, chest, abdomen, and sometimes the heart. It is caused by exposure to asbestos, a mineral that was widely used in construction and manufacturing industries.
If you or a loved one has been exposed to asbestos, it is essential to be aware of the symptoms of mesothelioma. Early detection and treatment can significantly improve your chances of a positive outcome. In this article, we will discuss the common symptoms of mesothelioma, risk factors, and how to seek help.

What is Mesothelioma?
Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, chest, abdomen, and sometimes the heart. The cancer develops when a person inhales or ingests asbestos fibers, which then become lodged in the mesothelial cells that line these organs.
Over time, these fibers cause inflammation and scarring, which can lead to the development of cancerous tumors. It can take several decades for mesothelioma to develop after exposure to asbestos, which is why it is often diagnosed in people over the age of 60.
Types of Mesothelioma
There are several types of mesothelioma, and the symptoms and treatment options may vary depending on the location and stage of the cancer. The most common types of mesothelioma include:
| Type of Mesothelioma | Location | Common Symptoms |
|---|---|---|
| Pleural mesothelioma | Lungs and chest cavity | Chest pain, shortness of breath, coughing, fatigue |
| Peritoneal mesothelioma | Abdomen | Abdominal pain, swelling, nausea, vomiting, weight loss |
| Pericardial mesothelioma | Heart | Chest pain, shortness of breath, heart palpitations |
Pleural mesothelioma is the most common type, accounting for about 75% of all mesothelioma cases. Peritoneal mesothelioma is the second most common type, accounting for about 20% of cases. Pericardial mesothelioma is the rarest form, accounting for less than 1% of cases.
Symptoms of Mesothelioma
The symptoms of mesothelioma can vary depending on the type and stage of the cancer. In the early stages, there may be no symptoms at all, or they may be very mild and easily overlooked. As the cancer progresses, it can cause more noticeable and severe symptoms, including:
Chest pain and shortness of breath
Chest pain and shortness of breath are among the most common symptoms of pleural mesothelioma. These symptoms occur when the tumor grows and puts pressure on the lungs or the lining of the chest cavity. The pain may be severe and persistent, and it may be difficult to breathe deeply.
Coughing
A persistent cough is another common symptom of pleural mesothelioma. It may be dry or produce mucus, and it can occur at any time of day or night. Coughing can be especially severe when lying down or during physical activity.
Fatigue
Fatigue is a common symptom of all types of mesothelioma, and it can be caused by the cancer itself or by other factors such as chemotherapy or radiation therapy. Fatigue can make it difficult to carry out daily activities, and it may lead to feelings of weakness, exhaustion, and sleepiness.
Abdominal pain and swelling
Abdominal pain and swelling are the most common symptoms of peritoneal mesothelioma. These symptoms occur when the cancer grows and puts pressure on the organs in the abdomen. The pain may be severe and persistent, and it may be accompanied by nausea, vomiting, and changes in bowel habits.
Heart palpitations
Heart palpitations are a common symptom of pericardial mesothelioma. These occur when the cancer grows and puts pressure on the heart or the lining of the heart. Heart palpitations can feel like a fluttering or racing heart, and they may be accompanied by chest pain, shortness of breath, and dizziness.
Other symptoms
In addition to the symptoms listed above, mesothelioma can cause a variety of other symptoms depending on the location and stage of the cancer. These may include:
- Unexplained weight loss
- Night sweats
- Fever
- Difficulty swallowing
- Blood clotting disorders
Diagnosing Mesothelioma
Diagnosing mesothelioma can be challenging because the symptoms are similar to those of other respiratory and gastrointestinal diseases. In addition, mesothelioma can take several decades to develop after exposure to asbestos, making it challenging to link the cancer to a specific event or exposure.
If you are experiencing symptoms of mesothelioma, your doctor may order several tests to help make a diagnosis, including:
- Chest X-ray
- CT scan or MRI
- PET scan
- Blood tests
- Biopsy
A biopsy is the most definitive way to diagnose mesothelioma. It involves taking a small tissue sample from the affected area and examining it under a microscope. If mesothelioma is diagnosed, your doctor will order additional tests to determine the stage of the cancer and develop a treatment plan.
Treatment Options
The treatment options for mesothelioma depend on the location and stage of the cancer, as well as your overall health and other factors. The goal of treatment is to remove the cancer or slow its growth, relieve symptoms, and improve quality of life.
The most common treatment options for mesothelioma include:
- Surgery
- Chemotherapy
- Radiation therapy
- Targeted therapy
- Immunotherapy
If mesothelioma is diagnosed early, surgery may be an option to remove the cancerous tissue. Chemotherapy and radiation therapy are often used in combination with surgery or as standalone treatments to shrink or kill cancer cells. Targeted therapy and immunotherapy are newer treatment options that work by targeting specific pathways or cells involved in the growth and spread of cancer.
Prevention and Risk Factors
The most significant risk factor for mesothelioma is exposure to asbestos. Asbestos is a mineral that was widely used in construction and manufacturing industries from the 1940s to the 1970s. It was used in insulation, roofing materials, flooring, and many other products.
If you have been exposed to asbestos, there are several steps you can take to reduce your risk of developing mesothelioma, including:
- Avoiding further exposure to asbestos
- Wearing protective clothing and masks in areas where asbestos is present
- Having your home or workplace tested for asbestos
- Following proper safety guidelines if you work with or around asbestos
Other risk factors for mesothelioma include smoking, radiation exposure, and certain genetic factors. However, these factors are not as significant as asbestos exposure.
Frequently Asked Questions
What is the survival rate for mesothelioma?
The survival rate for mesothelioma depends on several factors, including the type and stage of the cancer, as well as the age and overall health of the patient. The overall five-year survival rate for mesothelioma is around 10%, but this can vary widely depending on individual circumstances.
Can mesothelioma be cured?
Currently, there is no cure for mesothelioma. However, early detection and aggressive treatment can significantly improve a patient’s chances of survival and quality of life.
Is mesothelioma hereditary?
Mesothelioma is not usually hereditary. However, there are some rare genetic mutations that may increase a person’s risk of developing the disease. If you have a family history of mesothelioma or other cancers, you should talk to your doctor about genetic testing and risk assessment.
Can mesothelioma be prevented?
The best way to prevent mesothelioma is to avoid exposure to asbestos. If you work in an industry where asbestos is present, make sure you follow proper safety guidelines and wear protective clothing and masks. If you live or work in an older building, have it tested for asbestos, and have it removed if necessary.
What should I do if I have been exposed to asbestos?
If you have been exposed to asbestos, you should talk to your doctor about your risk of developing mesothelioma. Your doctor may recommend regular screening tests to monitor your health and detect any signs of cancer early. You should also follow proper safety guidelines if you work with or around asbestos, and take steps to avoid further exposure.
How can I find a mesothelioma specialist?
If you have been diagnosed with mesothelioma, it is essential to seek treatment from a specialist who has experience treating this rare and aggressive cancer. You can find a mesothelioma specialist through the National Cancer Institute, the Mesothelioma Applied Research Foundation, or by contacting a cancer center or hospital in your area.
Can mesothelioma affect non-smokers?
Yes, mesothelioma can affect non-smokers. However, smoking can increase the risk of developing lung cancer, which can be mistaken for mesothelioma. If you are a non-smoker and have been diagnosed with mesothelioma, your doctor will need to rule out lung cancer as a potential cause of your symptoms.
