What is Mesothelioma?
Table Of Contents
Causes and Risk Factors
Mesothelioma is primarily caused by inhaling or ingesting asbestos fibers. Once inside the body, these fibers can cause inflammation and scarring, leading to abnormal cell growth. Risk factors include:
- Occupational exposure: Construction, shipbuilding, manufacturing, and military service increase the risk.
- Secondhand exposure: Family members of those working with asbestos may be exposed through clothing or tools.
- Environmental exposure: Naturally occurring asbestos in soil or industrial areas may pose a risk.
- Genetic factors: Some individuals may have a genetic predisposition that makes them more susceptible.
Symptoms of Mesothelioma
Symptoms vary based on the type and stage of the disease. Common signs of pleural mesothelioma include:
- Persistent cough
- Shortness of breath
- Chest pain
- Unexplained weight loss
- Fatigue
- Fluid buildup around the lungs (pleural effusion)
If mesothelioma affects the abdomen (peritoneal mesothelioma), symptoms may include abdominal pain, swelling, nausea, changes in bowel habits, and loss of appetite. These symptoms can often be mistaken for other less serious conditions, so it’s important to consult a healthcare professional if you experience them.
Diagnosis and Testing
Early diagnosis improves treatment options and outcomes. A comprehensive evaluation may include:
- Imaging tests: X-rays, CT scans, and MRIs detect abnormalities in lung or abdominal tissue.
- Biopsy: A sample of affected tissue is examined for cancer cells.
- Blood tests: Biomarker testing helps assess the likelihood of mesothelioma.
- Pulmonary function tests: Measure lung efficiency and breathing capacity.
Treatment Options
Treatment depends on the stage, location, and overall health of the patient. Options may include:
- Surgery: Removal of cancerous tissue, which may involve part of the lung or surrounding lining.
- Chemotherapy: Medications that target and slow cancer cell growth.
- Radiation Therapy: High-energy beams to shrink tumors and relieve symptoms.
- Immunotherapy: Boosts the body’s immune system to fight cancer cells.
- Clinical Trials: Research-based treatments that offer new approaches for managing mesothelioma.
Managing Mesothelioma
A multidisciplinary approach can help improve comfort and quality of life. Supportive therapies may include:
- Pain management: Medications and techniques to alleviate discomfort.
- Oxygen therapy: Helps improve breathing efficiency.
- Nutritional support: Maintaining strength and immune function through diet.
- Pulmonary rehabilitation: Exercise and breathing techniques to optimize lung function.
Frequently Asked Questions
0
What is the life expectancy for someone with mesothelioma?
Life expectancy varies based on the stage at diagnosis, overall health, and treatment response. Early detection and aggressive treatment can improve outcomes.
0
Can mesothelioma be cured?
There is no definitive cure, but treatment can manage symptoms, slow disease progression, and improve quality of life.
0
Who is at risk for mesothelioma?
Individuals with prolonged asbestos exposure, especially in high-risk occupations, have the greatest risk.
0
What are the early signs of mesothelioma?
Early symptoms include persistent cough, shortness of breath, chest or abdominal pain, and unexplained weight loss.
0
How is mesothelioma different from lung cancer?
Mesothelioma affects the lining of the lungs, while lung cancer develops inside the lung tissue. They have different causes, treatment approaches, and progression rates.
