See: http://journal.publications.chestnet.org/data/Journals/CHEST/21748/45.pdf It is a distinct entity from pulmonary fibrosis and the prognosis is considerably better because asthma is very treatable with bronchodilators and anti-inflammatory drugs. ...Read more

What is mesothelioma?

What is mesothelioma?

Ca of lung lining: Your lungs are surrounded by a lubricated lining called the pleura. This lining allows your lungs to move against your chest wall without friction. When these cells become cancerous, it is called a malignant mesothelioma. Mesothelioma are difficult cancers with few effective treatments. A single day of radiation to the biopsy site can prevent local invasion. ...Read more

What is the difference between emphysema and lung cancer?

Different things: Emphysema is destruction of lung tissue from (most often) smoking. Lung cancer is an abnormal growth of lung tissue that can cause destruction of many tissues, not just lung. They are completely different diseases. But, because the most common cause of lung cancer is smoking, many times patients with lung cancer have emphysema and vice versa. ...Read more
