question: My sister has been coughing for 1 month. A doctor suggested that she take an x-ray. The result came out a saying that there are suspicious densities on her upper lobe and apicolordotic view is suggested . Her doctor is currently on leave and we are already worried about the result, we cant wait for her to comeback. What are the possible diseases that may have caused this densities? Also, what maybe the cause for having her take this apicolordotic view.
