Thank you for the information regarding Tabrecta. I'm so glad she is showing improvement. I started on it about 1 & 1/2 years ago taking four pills a day now I am down to two a day. I have had a lot of side effects, mainly swelling, but also dizziness's & balance issues. About six months ago the doctor said I had some diminishing of my lung cancer which is great, I just wish it had all gone away. He said I don't need another CT scan for six months, but I do need to continue the medicine. Good luck to your Mom & God bless.
