Hello Karen Thank you so much for the information I am being treated at Moffitt Cancer center in Tampa Fl My oncologist is a lung cancer oncologist.I have had mecukar testing done in the past and they showed zero mutations I had to leave Moffitt for a couple of years because they would not prescribe Opdivo After getting consultations at Duke ,Md Anderson and Mayo clinic I ended up at Fl Cancer Specialists who were willing to give me Opdivo I remained with .offitt for Neuro.After 3 years at Fl Cancer Specialists I requested a new thoracic oncologist at Moffitt.Six months later gave me a different thoracic oncologist.I asked for Opdivo and he complied My latest progression in my lung was Oct .2022.Iasked Moffitt to order molecular testing My oncologist said it's not covered by insurance I then called Foundation One and arranged the tests I show a Brafv6000 mutation I then asked my .offitt thoracic oncologist if we could explore other drugs and he said no we will stick with Opdivo Im very stressed out with the progression Thank you again
