• Pleural mesothelioma is the most common form of the cancer, affecting the lining of the lungs, called the pleura.
• Peritoneal mesothelioma is the second most common form of the cancer and develops in the lining of the abdomen, called the peritoneum.
• Pericardial mesothelioma develops in the membrane that surrounds the heart, called the pericardium.
• Testicular mesothelioma is the rarest form of the cancer and develops in the membranous lining surrounding the testicles, called the tunica vaginalis.
