@dougmck, I hope you are recovering from the biopsy. There's a lot of waiting through the diagnosis process, which isn't easy, but it can be beneficial.
I can share my own story but remember that it's just one example. My original biopsy was also taken from just a lymph node. There were enough cancerous cells in the lymph node to confirm that it was cancer. The pulmonologist felt there was no need to put me through the risk of going into the lung to get access to the mass. The results from my liquid biopsy did take two weeks to come back. At the time, I wasn't sure that waiting was a good idea. I even questioned if I should have some chemo while we waited. I was symptomatic and getting sicker. Now, I can appreciate the wait because I did have a targetable mutation. Because of that, I was able to avoid chemo and radiation. When I've had a few scares since then, I try to remind myself that unless I'm in the Emergency Department, I have some time to take a breath, review options, get second opinions, and wait (just a bit) for tests.
Do you know if molecular testing/biomarker testing was completed when you were diagnosed in 2008, or with any of your other nodules?
