Confused information.

Hi 

I have been told I have a mass in my left lung. 

They drained 2.5ltrs of fluid from it, and tried to get a needle biopsy, but unfortunately no result. 

They now have me in for a bronchoscopy next week and hope to get a result from that. 

In the meantime I'm very confused as to what type of cancer it is, or what stage its at. 

That I think is most alarming.
