I was diagnosed with Stage IV left lung ca with metastasis lymph nodes. I took tarceva for 2 weeks. I develop plueral effusion. I had pluerodesis to solve chronic effusion. Was on 2 chemo drugs that failed. I quit chemo after 5 mos. My oncologist said I have 6-12 months to live w/ chemo. That was August 23,2010. Currently, I feel really good. The cough dissapeared, sob minimal, no chest pains or shoulder or neck pains. What happened? I am 62 female, non smoker. Thank you.
