Oncology appointment went well. I have EGFR exon 21 mutation which is appropriate for Tagrisso TKI medication. However, it’s cost prohibitive (Medicare Part D). So we will process paperwork with AstraZenecs for assistance. If assistance is denied, then no treatment (no chemo, no immune therapy). We’ll just watch it. Also discovered that this mutation likes to travel to the brain. Will consider a MRI. Not comfy being stuffed in a tube. Thanks for asking.
