Hi there, the bronchoscopy is necessary fore her treatment. My husband has stage 4 lung cancer and he said it was the worst thing he had ever experienced as he was doing OK until then!  So her lung function test will be done eventually but it's now a case of waiting to see what results come back so they can treat her cancer properly.  It's a tough road to travel with lots of things happening so it's hard but you just have to be patient until her results come back. Hope this helps a bit.  Kind regards, Carol 

Hi, I was diagnosed with lung cancer last November and had a broncoscopy early December.... they need to take samples of the cancer to decide which treatment is best. I felt absolutely awful after the broncoscopy, with a horrendous cough and very chesty..... took about a week to subside. Don't worry too much about the lung function test, just concentrate on getting the treatment started . Hope she gets treatment started soon . Any questions, don't hesitate to ask .x

Hi, I've had 4 lots of chemo with immunotherapy, which reduced the cancer by half, and since February have been just on immunotherapy every 3 weeks. At the moment it is stable, hopefully will stay that way for a good while . 
good luck with the treatment ... the NHS  has been amazing .
