One of the most common types of mesothelioma is malignant pleural mesothelioma, which often originates within the chest cavity and can, at times, involve the lungs as well. This form of mesothelioma can spread to numerous organs in the body, even the brain, and tends to do so more frequently.
One of the most questions that is asked among people who are worried about mesothelioma is how common it is for people to contract it. Mesothelioma is still seen as a rare cancer, even though reports of patients who have been diagnosed has icreased in the past 20 years. Around 2,000 new cases of mesothelioma have been diagosed in the United States every year. Studies have shown that mesothelioma shows up in men more often then women. While it is true that the risk for this disease can increase with age, it can still be contracted at any age.
Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. Asbestos are any of a group of minerals that can be fibrous, many of which are metamorphic and are hydrous magnesium silicates. In this disease, malignant cells develop in the mesothelium, which is a protective lining that covers most of the body’s internal organs. Its most common site is the pleura (outer lining of the lungs and chest cavity), but it may also occur in the peritoneum (the lining of the abdominal cavity) or the pericardium, a sac that surrounds the heart.
