Hi,  Following a CT for an orthopaedic issue and a lovely surprise appointment for the lung clinic I have just had a Bronchoscopy and biopsy.  The consultant talked me through the previous CT again  and then said they were just going to take a little look today to see exactly where the tumour is in relation to blood vessels, etc and to take a biopsy sample.  Afterwards he came to see me and showed me photographs of the the tumour on an ipad and explained it is obstructing my upper left bronchus and lobe.  I asked whether he thought is was cancer and he said in his opinion it looked very much like a cancerous tumour and that the biopsy would confirm this and what type, etc. He then went on to explain the mulit-discipliniary meeting and my subsequent appointment.  He said I was strong an healthy and it was likely they would take an agressive treatment approach. Firstly, can he really tell it's cancer by the camera work?  Secondly, what is an agressive treatment plan? 

Thanks x
