Cancer Facts : How Does Lung Cancer Develop?
Lung cancer develops when smoking, air pollutants and free radical formation damages sensitive lung tissue, causing the cellular DNA to restructure and malfunction. Avoid lung cancer by quitting smoking with information from a doctor in this free video on cancer.
Black Lung Disease Coal Dust Occupational Disease 1980
In the last decade, over 10,000 miners have died of coal workers' pneumoconiosis, or what is commonly called black lung disease.1 Black lung disease, which is caused by inhaling coal mine dust, results in scarring of the lungs and emphysema, shortness of breath, disability, and premature death. While the prevalence of black lung disease had decreased by about 90% from 1969 to 1995 following the enactment of the Coal Mine Health and Safety Act, the downward trend of this disease in coal miners has stopped. Since 1995, the prevalence of black lung cases has more than doubled. Many current underground miners (some as young as in their 30s) are developing severe and advanced cases. Identification of advanced cases among miners under age 50 is of particular concern, as they were exposed to coal-mine dust in the years after implementation of the disease prevention measures mandated by the 1969 federal legislation. An increased risk of pneumoconiosis has also been associated with work in certain mining jobs, in smaller mines, in several geographic areas, and among contract miners
Lung Disease: Pulmonary Fibrosis
Learn about pulmonary fibrosis, a set of diseases that cause progressive scarring inside the lungs. Over time the lungs are slowly replaced with scar tissue, which causes airways to restrict airflow, making it difficult to breath and to get enough oxygen. Doctors, patients and researchers are hoping clinical trials will lead to a drug that prevents lung function from worsening ultimately allowing patients to live longer.
