[|Human|] 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.
[|AI|]  Hi, I have reviewed your concernSometimes cancer can autoregress in some patients. It is a very lucky event in which the malignant clone undergoes autodestruction. Seen with neuroblastomas it is rarely seen in lung cancers too. I would like to congratulate you on these reductions of symptoms. However, would advise you to get a PET scan or a CT scan done to see if there is any residual tumor that can now be treated aggressively and removed completely. I hope this yellowish you a great healthy life
