I'll be 74 in two months, diagnosed with NSCLC stage 4 in September 2021. I had a bronchoscopy to determine if I had a mutation and sure enough, it came back as EGFR 19 deletion which enabled me to start targeted therapy (pill) in December 2021. I just had quarterly CT scan yesterday and all that remains is a 4mm nodule in the lower right lobe - where it all started - and a few scattered sub-4mm nodules in both lungs. Lymph nodes that were affected are now normal, one metastases to brain was handled by one session of radiosurgery, and lesions to left iliac bone and T9 vertebrae were taken care of by the targeted therapy I take. I know it's scary and very overwhelming but take a deep breath, write down any and all questions that you have and advocate for yourself every step of the way. Try hard to remain positive because positivity really impacts your health in a good way. Gld bless you.
