Hi,  I had lung cancer 2 years ago and had a lung removed followed by chemo.  Eventually I was told I was cancer free.  In February this year i was given an x-ray for pain in my back.   A week later my cancer nurse phoned to tell me that the cancer is back. I am devastated and terrified. My oncologist says it is in lymph nodes in my chest.   I have had three bouts of Immunotherapy,  which I had never heard of but seems to have good results.  I have to get this treatment every 3 weeks for 2 years which I am happy to do if it helps. I just wondered if anyone else has had this treatment.
