2 days ago I was told that I probably have mestastisized (sp) cells in my lungs that come from a primary cancer source. This diagnosis comes about as a result of a CT scan of my chest. I am scheduled for a lung biopsy tomorrow. I have NO symptoms. No other scans, head and abdomen, showed any abnormalities. How can a CT scan result show such definitive answers (90% probablility according to my Dr.)?? First I was scared to death and now I'm really ticked off! Any thoughts?
