Hi Sloan, I came to your page after seeing your question about fatigue. It sounds like you've had some treatment already. Is your cancer responding to the treatments?
I was diagnosed in 10/2012 with NSCLC. Like you, I had no symptoms, but I was diagnosed at stage IV. It was definitely a big surprise!!
My oncologist told my husband he expected I had about 4 months to live. If I hadn't been able to get into a clinical trial for Opdivo, an immunotherapy drug, I probably wouldn't have made a year. But, when I got into the trial, everything changed. I felt good again and my tumors were stopped in their tracks. I still have them ... I still have to have treatments every two weeks ... but we are co-existing nicely! We have a deal - they can stay where they are as long as they don't try to grow or spread!!

(Joking)
Anyway, there's hope. Please know, there's hope. And, if your oncologist doesn't feel there's hope, too, then you might want to go to a different one.
Bless your kids. I'm glad you have loved ones there to go along this journey with you!
