What Is Mesothelioma?
Mesothelioma is a type of cancer that develops in the thin layer of tissue covering internal organs, known as mesothelium. Medical professionals categorize this cancer into different types depending on which area of the mesothelium is affected. The most common form affects the tissue surrounding the lungs (pleura), known as pleural mesothelioma. Rarer types may impact tissue in the abdomen (peritoneal mesothelioma), around the heart, or around the testicles.
Mesothelioma is an aggressive form of cancer originating in the lining of various bodily cavities, most commonly the pleura surrounding the lungs. It can also affect the lining of the abdomen (peritoneum) or the tissue surrounding the testicles (tunica vaginalis).
Mesothelioma Symptoms
Initially, individuals may experience subtle signs such as fatigue or mild discomfort. However, as the tumor grows and spreads, symptoms become more pronounced. Accumulation of fluid between the lung and chest wall (pleural effusion) can lead to shortness of breath, while the invasion or compression of nearby nerves may result in chest pain. Left untreated, mesothelioma can metastasize to nearby lymph nodes and other organs, exacerbating the severity of symptoms and often proving fatal.
Pleural mesothelioma symptoms:
- Breathing difficulties
- Chest pain
- Difficulty swallowing
- Nerve and spinal cord compression
- Accumulation of fluid in chest (pleural effusion)
- Compression of lung tissue
Symptoms of mesothelioma also vary depending on its location.
Pleural mesothelioma, affecting the tissue around the lungs, may present with chest pain, painful coughing, shortness of breath, skin lumps on the chest, and unexplained weight loss.
Peritoneal mesothelioma, occurring in the abdomen, can manifest as abdominal pain, swelling, nausea, and weight loss.
Other forms of the disease, such as pericardial mesothelioma affecting the heart lining or mesothelioma of tunica vaginalis around the testicles, have less defined symptoms due to their rarity.
If experiencing concerning symptoms, it’s essential to consult a doctor, especially if there’s a history of asbestos exposure, as signs of mesothelioma can resemble those of other conditions.
What Causes Mesothelioma?
- Occupational exposure to asbestos in industries such as construction, shipbuilding, mining, and manufacturing.
- Secondary exposure to asbestos fibers carried home on the clothing of family members who work with asbestos.
- Environmental exposure to asbestos from natural deposits or contaminated sites.
- Living in buildings with asbestos-containing materials (e.g., insulation, roofing, flooring) that become airborne due to deterioration or renovation.
- Military service, particularly in branches such as the Navy, where asbestos was commonly used in ships and submarines.
- Use of asbestos-containing consumer products such as talcum powder, brake pads, or insulation.
- Asbestos exposure during demolition or renovation of older buildings containing asbestos materials.
- Exposure to asbestos during firefighting or rescue operations where buildings or structures with asbestos-containing materials are involved.
- Exposure to asbestos through natural disasters or events that disturb asbestos-containing materials, releasing fibers into the air.
Additionally, radiation therapy, particularly when administered at high doses to the chest, has been linked to an elevated risk of developing mesothelioma. Additionally, genetic predispositions may play a role, with approximately 1% of cases resulting from inherited genetic mutations.
Asbestos, a fibrous mineral once widely used for its insulating and fire-retardant properties, can lead to mesothelioma when its microscopic fibers are inhaled, causing irritation and inflammation in the lung lining. Over time, this irritation can progress to the development of cancerous cells.
*Eight out of 10 individuals diagnosed with mesothelioma have reported prior exposure to asbestos, which remains the foremost risk factor associated with this disease.
The Link Between Asbestos and Mesothelioma
Asbestos exposure significantly increases the risk of mesothelioma, with most cases believed to be linked to this hazardous substance. Asbestos, a naturally occurring mineral, boasts strength and heat resistance, rendering it useful in various applications like insulation, brakes, and flooring.
When disturbed, such as during mining or insulation removal, asbestos releases dust containing fibers that, when inhaled or ingested, settle in the lungs or stomach, leading to irritation and potentially cancer. The exact mechanism behind this process remains unclear, but the latency period for mesothelium cancer to manifest post-exposure can range from 20 to 60 years or more.
Despite widespread exposure, not all individuals exposed to asbestos develop cancer, suggesting additional factors may contribute to the development of cancers. These factors include direct exposure to asbestos at work or home, living with someone who handles asbestos, family history of mesothelium related cancer, and prior chest radiation therapy for cancer, all of which heighten the risk of developing the disease.
Beyond asbestos exposure, certain occupations are associated with an increased risk of developing mesothelioma due to potential exposure to asbestos-containing materials. These include professions such as shipbuilding, construction, and industrial work, where asbestos was commonly used before its health risks were fully understood.
Secondary exposure to asbestos fibers is also a concern, particularly for individuals living with workers who handle asbestos, as the fibers can be inadvertently carried home on clothing and skin.
Preventing Asbestos Exposure
To reduce your risk of mesothelioma, take steps to minimize your exposure to asbestos. Determine whether you work with asbestos by asking your employer about potential exposure risks. Occupations with higher chances of encountering asbestos fibers include asbestos miners, electricians, plumbers, pipefitters, insulators, shipyard workers, demolition workers, brake mechanics, selected military personnel, and home remodelers.
Adhere to safety regulations set forth by your employer, including wearing appropriate protective gear and following decontamination procedures such as showering and changing clothes before leaving work. Additionally, exercise caution around asbestos in your home, especially in older buildings where it may be present.
While removing asbestos can pose significant health risks, leaving it undisturbed is often safer. Consult professionals trained to detect asbestos and consider testing the air in your home to assess potential hazards. If asbestos removal is necessary, enlist the services of qualified experts to handle the process safely and effectively.
Similarly, individuals living in older homes suspected of containing asbestos should exercise caution and seek professional assistance for testing and, if necessary, removal. By adopting these preventive measures, individuals can minimize their exposure to asbestos and reduce their risk of developing cancer.
Diagnosing Mesothelioma
Doctors use several tests and procedures to diagnose mesothelioma. A comprehensive healthcare plan may involve using one or more diagnostic exams to detect and monitor mesothelioma. Read more below.
Diagnostic imaging
X-rays
X-ray scans commonly detect signs of mesothelioma by capturing images of the chest or abdomen. They can reveal abnormalities like pleural thickening or fluid buildup. Additionally, X-rays help monitor disease progression and assess treatment effectiveness over time.
Computed tomography (CT) scans
CT scans are instrumental in diagnosing mesothelioma as they offer cross-sectional images of the chest or abdomen, allowing for the detection of tumors, pleural thickening, and other abnormalities with high precision. They aid in staging the disease and guiding treatment decisions.
Magnetic resonance imaging (MRI)
MRI scans provide detailed images of soft tissues and can help detect mesothelioma tumors in the chest or abdomen, aiding in accurate diagnosis and assessment of tumor size, location, and involvement with nearby structures, which is crucial for treatment planning.
Positron emission tomography (PET) scans
PET scans are valuable for detecting mesothelioma metastases and assessing the extent of the disease by highlighting areas of increased metabolic activity, helping doctors determine the spread of cancer beyond the primary site and plan appropriate treatment strategies.
Biopsy
Tissue samples are collected through minimally invasive procedures such as thoracoscopy (for pleural mesothelioma) or laparoscopy (for peritoneal mesothelioma). These samples are then analyzed by a pathologist to confirm the presence of mesothelioma cells.
Blood tests
Although there’s no specific blood test for diagnosing mesothelioma, certain biomarkers may be elevated in individuals with mesothelioma, such as mesothelin or fibulin-3.
Pulmonary function tests
These tests assess lung function and may help evaluate the impact of mesothelioma on respiratory function.
Thoracentesis or paracentesis
These procedures involve the removal and analysis of fluid buildup in the chest (for pleural mesothelioma) or abdomen (for peritoneal mesothelioma), which can help in diagnosis and management.
What is the best imaging for mesothelioma?
The best imaging modalities for diagnosing mesothelioma include computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans. CT scans are particularly useful for identifying pleural thickening and effusions, while MRI scans provide detailed images of soft tissues and can help determine tumor extent. PET scans are helpful in assessing metabolic activity and detecting metastases. Ultimately, the choice of imaging depends on factors such as the patient’s clinical presentation and the suspected location and extent of the disease.
Does mesothelioma show up on CT scan?
Yes, mesothelioma can typically be visualized on a CT (computed tomography) scan. CT scans are often used as a primary imaging modality for diagnosing mesothelioma because they can reveal abnormalities such as pleural thickening, pleural effusions, and the presence of tumors within the chest cavity. However, additional imaging tests such as MRI (magnetic resonance imaging) or PET (positron emission tomography) scans may also be used to further evaluate the extent of the disease and its involvement with nearby structures.
Can ultrasound detect mesothelioma?
Ultrasound imaging is not typically used as the primary method to detect mesothelioma. While ultrasound can be helpful in visualizing fluid buildup in the chest or abdomen, which may occur with mesothelioma, it is not as sensitive or specific as other imaging modalities such as CT scans or MRI in detecting solid tumors or assessing the extent of the disease. Therefore, ultrasound is not commonly used as a standalone tool for diagnosing mesothelioma, but rather as a complementary test in certain situations, such as guiding procedures like thoracentesis or paracentesis to drain fluid for further analysis.
