Mesothelioma Cancer from Diagnosis to Treatment
What Is Mesothelioma?
Mesothelioma is a rare and aggressive cancer that develops in the mesothelium - the thin protective lining covering the lungs, chest wall, abdomen, and other internal organs.
It most commonly affects the pleura | lining of the lungs, but it can also occur in the peritoneum | abdomen, pericardium | heart, or tunica vaginalis | testes.
The main cause of mesothelioma is long-term exposure to asbestos fibers, which were widely used in construction, shipbuilding, and insulation materials.

Types of Mesothelioma
Pleural Mesothelioma
Affects the lining of the lungs.
Most common type | about 75-80% of all cases.
Peritoneal Mesothelioma
Occurs in the lining of the abdomen.
Accounts for 10-15% of cases.
Pericardial Mesothelioma
Develops in the lining around the heart.
Very rare | less than 1% of cases.
Testicular Mesothelioma
Affects the lining of the testes.
Extremely rare.

Cell Types
Epithelioid
Most common and treatable form.
Sarcomatoid
More aggressive and resistant to therapy.
Biphasic
Contains both epithelioid and sarcomatoid cells.

2. Signs and Symptoms
Pleural Mesothelioma:
• Persistent chest or lower back pain
• Shortness of breath
• Coughing, sometimes with blood
• Fatigue and weakness
• Unexplained weight loss
• Pleural effusion | fluid buildup around lungs
Peritoneal Mesothelioma:
• Abdominal pain and swelling
• Nausea and vomiting
• Loss of appetite
• Bowel changes
• Unexplained weight loss
Pericardial Mesothelioma:
• Chest pain
• Irregular heartbeat
• Shortness of breath

3. Diagnostic Procedure
Medical History & Physical Exam
Doctor checks for asbestos exposure and related symptoms.
Imaging Tests
Chest X-ray:
Detects pleural thickening or fluid buildup.
CT Scan / MRI:
Identifies tumor size and spread.
PET Scan:
Detects active cancer cells throughout the body.
Fluid Analysis
Thoracentesis or paracentesis: Fluid drawn from the chest or abdomen is examined for cancer cells.
Biopsy
Needle or surgical biopsy confirms mesothelioma by identifying cancerous mesothelial cells.
Staging
Determines extent of spread | Stage I-IV, guiding treatment planning.

4. Treatment Options
➛ Surgery
Pleurectomy/Decortication:
Removes affected pleura and nearby tissue.
Extrapleural Pneumonectomy:
Removes one lung and part of the diaphragm or heart lining.
Peritonectomy:
Removes abdominal tumors.
➛ Chemotherapy
Most common drugs:
Pemetrexed and Cisplatin.
Shrinks or slows tumor growth.
➛ Radiation Therapy
Used after surgery or for symptom relief.
Intensity-modulated radiation therapy precisely targets tumors.
➛ Immunotherapy
Boosts the body's immune system to fight cancer.
Nivolumab and Ipilimumab are approved options for pleural mesothelioma.
➛ Targeted Therapy
Focus on specific genetic mutations.
Offers new hope for advanced cases.
➛ Palliative Care
Manages symptoms like pain, breathlessness, and fatigue.
Focuses on improving quality of life.
