I have been on Tagrisso 1st line for 6 months. my 3rd scan last monday showed slight progression, 2 new nodules ( 16mm- 1cm ) and one grew slightly. my next treatment plan is up in air pending PET, MRI and biopsy. Any recommendation or what your medical team is doing now will be helpful. Also, I am switching over from my general oncologist in NJ to MSK at NY.
