@firefly33 Thank you. I see the doctor tomorrow, 1/14, for a follow up. I hope my cell counts are okay. I've only been on tagrisso for 11 days and had my 1st chemo on Jan.2. I was diagnosed with stage IV lung cancer about a month ago with metastases to the bone and brain. I got radiation on my head where there was a painful bump, that now has gone down.
