What is Mesothelioma?

Mesothelioma is a rare and aggressive cancer that develops in the thin layer of tissue called the mesothelium, which covers most internal organs. It is most commonly caused by exposure to asbestos—a group of minerals used in construction and manufacturing. The most affected area is the lining of the lungs (pleura), but it can also occur in the abdomen (peritoneum), heart (pericardium), or testicles (tunica vaginalis).

Types of Mesothelioma

Mesothelioma is classified based on the location where the tumor develops. The main types include:

• Pleural Mesothelioma: The most common type, occurring in the lining of the lungs. It accounts for about 75% of cases.
• Peritoneal Mesothelioma: Occurs in the lining of the abdomen and is the second most common form.
• Pericardial Mesothelioma: A rare type that forms in the lining around the heart.
• Tunica Vaginalis Mesothelioma: Extremely rare, it affects the lining of the testicles.

Global Statistics (2024)

• Approximately 30,000 new cases of mesothelioma are diagnosed globally each year.
• In the United States, there are about 3,000 new diagnoses annually.
• Most cases are diagnosed in people aged 60 and older, and men are more commonly affected due to occupational exposure.
• The average life expectancy after diagnosis is 12–21 months, depending on the stage and treatment.

Symptoms of Mesothelioma

• Shortness of breath or difficulty breathing.
• Persistent cough or chest pain (pleural).
• Abdominal swelling and pain (peritoneal).
• Unexplained weight loss and fatigue.
• Fluid buildup around the lungs or abdomen.
• Nausea, fever, or bowel changes (in peritoneal cases).

Risk Factors

• Asbestos Exposure: The leading risk factor; even brief exposure can lead to mesothelioma decades later.
• Occupational Risks: Construction workers, shipyard workers, military veterans, and those in industrial settings face higher risks.
• Secondhand Exposure: Family members of workers exposed to asbestos can also be at risk.
• Radiation Exposure: Rare cases are linked to previous radiation therapy to the chest or abdomen.
• Genetics: Certain inherited gene mutations may increase susceptibility.

Diagnosis of Mesothelioma

• Imaging Tests: Chest X-rays, CT scans, and MRIs help detect abnormalities in the lungs or abdomen.
• Biopsy: A tissue sample is required to confirm the presence of mesothelioma cells.
• Blood Tests: Biomarkers like SMRP may assist in diagnosis, though not definitive alone.
• Thoracoscopy/Laparoscopy: Minimally invasive procedures used to visualize and sample tissue directly.

Treatment Options

• Surgery: In early-stage cases, surgery may be used to remove as much of the tumor as possible.
• Chemotherapy: Often used to shrink tumors, either before or after surgery, or for palliative care.
• Radiation Therapy: Targeted radiation can help manage pain and reduce tumor size.
• Immunotherapy: Helps the immune system recognize and destroy cancer cells; now FDA-approved for mesothelioma.
• Multimodal Therapy: Combines two or more treatments for a more effective approach.

Prevention and Early Detection

• Asbestos Safety: Avoiding exposure to asbestos is the best way to prevent mesothelioma. Use protective gear and follow safety protocols.
• Occupational Regulations: Compliance with workplace health standards helps reduce risk.
• Regular Screenings: For those exposed to asbestos, regular health check-ups and imaging may help with early detection.
• Awareness and Advocacy: Raising awareness of asbestos-related diseases supports preventive measures and research funding.

Prognosis

• Mesothelioma has a poor prognosis due to late detection in many cases.
• The 5-year survival rate is approximately 10%, though some patients live much longer with aggressive treatment.
• Early diagnosis, access to care, and participation in clinical trials may improve outcomes.
• Supportive and palliative care play a key role in improving quality of life.

Ongoing Research

• Immunotherapy Advances: New drugs are being developed to enhance immune response against mesothelioma cells.
• Gene Therapy: Experimental treatments aim to target mutations and repair damaged DNA.
• Biomarker Discovery: Research focuses on identifying better biomarkers for early detection and monitoring.
• Clinical Trials: Participation in trials gives patients access to cutting-edge treatments and contributes to science.

Mesothelioma Awareness Day

Mesothelioma Awareness Day is observed on September 26 each year. It is a time to honor those affected, raise awareness about asbestos exposure, and support research to find better treatments and ultimately a cure.
