Hello, my name is Ann. I was diagnosed with non small cell lung cancer last spring , 2016. I had lung surgery, lower left lobe removed along with chest lymph nodes. I have had chemo. and just finished radiation treatments. My recheck CT scan will be on Jan. 25, 2017. I will also meet with my two oncologists. My tumor that was removed allows me to be in a clinical study using optivo for early lung cancer through the company Alchemist. Not sure if I should proceed. Is this like chemo? Side effects? I do not have to make a decision until April, 2017. Thank you for any advise you may have.
