@nanajan, hmmm, I don't see the relationship. Tagrisso is a small molecule targeted therapy that enters a target cell and directly interferes with the cancer's efforts to make that a cancerous cell. It has no relationship with your immune system. But then again, I'm not an oncologist.

I've had lung cancer for six and a half years, metastatic for over four. I choose not to let the numbers determine my life but, instead, to live with hope, determination, and optimism. I encourage you to join me in living with hope, determination, and optimism, not just in health but in every challenge you face in life.
