Hi @lls8000, thanks for your reply. I practice Bikram yoga for about 10 years now it has been wonderful for my well being too. Answer to your question. No, I have not started any treatments yet. I join this group wanting to find out how many of us went through the same treatment (for EGFR exon 20) which is Chemo plus Rybrevant had a great result? As I read about horrible side effects during treatment. Is it worthy for me a nearly 80 years old lady to go through that route? English is my second language but I am willing to try to learn from all of you out there prior to accepting an Oncologist's recommendation. Apologize if there has any confusions with my language!
