I was originally diagnosed as NSCLC - squamous cell - and treated as such. Had chemo and radiation as such, then had the tumor removed - even though they said the treatment didn't shrink the tumor - and final path came back neuroendecrine carcinoma - typical carcinoid.
Was told that was a GOOD THING. Then about six months later my pneumologist told me different pathologists may not agree on the diagnosis, but let's "go with this for the time being". After years of misdiagnosis (believe me, I could write a book!) and lots of treatments, several surgery attempts - I have faired VERY well!!! I will tell you, however, still wage a "mental" war occasionally over the quacks that let this go for so long - and me for believing them - but that's another story.
I really only did research AFTER my surgery, because I didn't know the final path till I went for a followup with my surgeon. I didn't receive treatments for NE, because they thought they were dealing with NSC at the time. My onc., however did say it was a very slow growing type.
Good luck - like everyone said - take a minute to let all of this sink in and move on with your fight!! Now that you have the knowledge, you have the power - you go girl!
