My dad was having shortness of breath and pain in his test. X-Rays revealed very little. The Dr. couldn't hear breath sounds in his lower right lung. He then went for a CT Scan and the scan revealed a mass. The dr.'s did numerous blood test to rule out Pneumonia. They put him on Antibiotics any way and Advair. Sent him home to see if the Antibiotics help. Then he goes back for another CT Scan Sept.,2004. He worked at a Tank car company in East Gary,Indiana for 45 yrs. The Dr. asked him if he had ever been exposed to Asbestos. The mass in his lung is made up of stringy fibers. Dad used to mis powdered Asbestos with water to make a putty to fill holes in welds. He didn't use it all the time but he was exposed. What are his chances of having been poisoned by the Asbestos. Are the Asbestos causing this problem??????? :confused:
