I was diagnosed with stage 4 lung cancer (adenocarcinoma) in May 07'. I have had 11 treatment of chemo so far. I was told that my cancer is shinking. I was wondering if it can spread to my brain and bones even thought i was on chemo? I haven't had any more scans for the brain and bones. I'm due for another scan in 2 weeks should i have the other scans done as well? Has anyone been diagnosed with stage 4 lung cancer but not in the bones or brain? I want to know the survival rate for this kind of cancer. I'm to scared to ask the doctor how long I have.
