How Much Do You Know About Mesothelioma?

Approximately 3,000 new cases are diagnosed annually in the United States. How much do you really know about this disease? Take our quiz to test your knowledge and uncover scientifically proven facts about causes, symptoms, treatments, and legal rights.

Question 1: What Is the Primary Cause of Mesothelioma?

Answer:
Mesothelioma is caused by inhaling or ingesting asbestos fibers. Asbestos, a naturally occurring mineral once widely used in construction, insulation, and manufacturing, releases microscopic fibers that become trapped in the body. Over decades (typically 20–50 years), these fibers cause inflammation and genetic damage, leading to cancerous mutations. The U.S. Environmental Protection Agency (EPA) banned new asbestos uses in 1989, but legacy asbestos remains in older buildings and products.

Question 2: What Are the Most Common Symptoms of Mesothelioma?

Answer:
Symptoms vary by type (pleural, peritoneal, pericardial) but often include:

• Pleural (lungs): Chest pain, shortness of breath, persistent cough.
• Peritoneal (abdomen): Swelling, nausea, unexplained weight loss.
• Pericardial (heart): Irregular heartbeat, chest pressure.
  Symptoms typically appear in late stages, delaying diagnosis.

Question 3: Who Is Most at Risk for Mesothelioma?

Answer:
High-risk groups include:

• Workers: Construction, shipbuilding, mining, firefighting, and automotive industries.
• Military Veterans: Navy personnel exposed in ships and shipyards.
• Secondary Exposure: Family members of workers exposed to asbestos-laden clothing.
  The CDC reports that 55% of mesothelioma patients are aged 75+ due to the disease’s long latency period.

Question 4: How Is Mesothelioma Diagnosed?

Answer:
Diagnosis involves:

1. Imaging Scans: X-rays, CT scans, or MRIs to identify tumors.
2. Biopsies: Tissue samples analyzed for cancerous cells.
3. Blood Tests: Biomarkers like soluble mesothelin-related peptides (SMRPs) may aid detection.
   Early diagnosis is rare due to non-specific symptoms.

Question 5: What Are the Standard Treatment Options?

Answer:
Treatment depends on cancer stage and patient health:

• Surgery: Tumor removal (e.g., pleurectomy).
• Chemotherapy: Drugs like cisplatin and pemetrexed.
• Radiation Therapy: Targets residual cancer cells post-surgery.
• Immunotherapy: FDA-approved drugs like pembrolizumab (Keytruda®) for advanced cases.
  Clinical trials exploring gene therapy and targeted drugs are ongoing.

Question 6: Is Mesothelioma Always Linked to Asbestos Exposure?

Answer:
Yes. Over 80% of cases are directly tied to asbestos exposure. Rarely, radiation therapy or genetic mutations (BAP1 gene) may contribute, but asbestos remains the primary cause.

Question 7: Can Victims Pursue Legal Compensation?

Answer:
Yes. Many U.S. patients file lawsuits against negligent asbestos manufacturers or employers. Compensation may cover medical bills, lost wages, and pain/suffering. Asbestos trust funds (established by bankrupt companies) hold over $30 billion for claimants.

Question 8: How Can Mesothelioma Be Prevented?

Answer:

• Avoid Asbestos: Do not disturb old insulation or tiles. Hire professionals for removal.
• Follow OSHA Guidelines: Employers must provide protective gear and air quality monitoring in high-risk jobs.
• Regular Screenings: High-risk individuals should discuss early detection with doctors.

Question 9: What Is the Average Prognosis for Mesothelioma Patients?

Answer:
The 5-year survival rate is approximately 12%, with most patients surviving 12–21 months post-diagnosis. Factors like early detection, cell type (epithelioid has better outcomes), and overall health influence prognosis.

Question 10: Where Can Patients Find Support?

Answer:

• Medical Centers: Specialized hospitals like MD Anderson or Brigham and Women’s Hospital.
• Nonprofits: Mesothelioma Applied Research Foundation (MARF) offers clinical trial databases.
• Support Groups: The American Cancer Society provides counseling and peer networks.

Why This Knowledge Matters

Understanding mesothelioma empowers individuals to recognize risks, advocate for timely care, and explore legal options. While there’s no cure, advancements in immunotherapy and early detection are improving outcomes.
