On 4/13/2010 I went in to have a biopsy and a possible lobectomy. Once in surgery my pulmonary artery was severed and my left lung had to be removed to stop the bleed. I am 55 years old and have problems with longevity with any household items. I do have a lot of scar tissue on the right lung from granulomas. I find it gets worse with age. Is this normal??
