To Savanna01 and for all the kind people that have replied to my initial post.
The CT scan my wife had was not conclusive and on 28th June had a Bronchoscopy and was to wait until the results were through and an appointment was made for 11th July. However, she got a telephone call yesterday morning (Consultants meet on a Friday morning to discuss results and action plans) and suggested that the bronchoscopy was inconclusive but did not show any cancerous material. The shadow looks like an infection of some sort but they now want to do an invasive CT scan with needle biopsy recovery on Wednesday morning - a blood test also planned for the Tuesday morning to undertake a thorough blood test before the CT scan. So we have a light at the end of the tunnel, but it is dim but it is there!
We are both worried but have been thrown a life raft to cling on to.
