Hello everyone. 
 

just a post because I have no idea what to expect next. I'm living each day in fear and have been since the diagnosis in November. 
My lovely grandad (72) was diagnosed with stage 4 metastic lung cancer in November. It was a huge shock to us all, and still to this day as a family we can't accept the diagnosis, especially when he still isn't experiencing any lung cancer symptoms. 
We were told back in November without treatment we were looking at 3-6 month, and with successful treatment postentially up to 2 years. Fast forward to now, he has had the four rounds of chemo. MRI after the second round revealed the tumours had shrunk. The fourth cycle has just ended and he has had a scan, which we are anxiously awaiting results for. 
I have hundreds of questions and scenarios going around my head every minute of every day! What happens next? I am terrified that now treatment has stopped the worst will happen. We were told that immunotherapy could potentially be an option, but his PL1 (not sure what that is) is 20% and ideally the higher the better for immunotherapy to be effective. After the second scan the doctor told us he could not give a prognosis despite the previous one. He said that the tumours had significantly shrunk and things were going better than expected. 
I don't even really know why I'm writing this I just feel so confused and upset. I have spoken to Macmillan a couple of times, but I truly just feel like I'm living in fear. My grandad is the only dad I have ever known and I'm really struggling with the diagnosis. It's on my mind all of the time. The thought of losing him is unbearable. 
 

My heart goes out to anyone fighting cancer x
