Hi @donnatownsend, It seems like things are moving ahead, and you are compiling a great list of questions for your appointment/s. Remember while you are reading info about biopsies, cancer, etc. There are always multiple opinions, and each and every patient is different.
This is just my experience, but my primary tumor was deep in my left lung, the biopsy of the lymph node was enough to determine the type of cancer. That meant they were able to stop at the lymph node, rather than going deeper and into the lung; IE. less risk.
Hopefully you get the call for the bloodwork soon, you may want to reach out to see what's causing the holdup. Lung cancer treatments are getting more and more specialized, so the more info your providers have, the better, in my opinion.
