See I have issues with drs who immediately jump into palliative mode without a firm dx... That whole thing completely effects a person's mindset and overall health.
You don't know its cancer, and either do they.
Secondly if it is, there are trials you can try.
Thirdly - I know someone who had SCC - got though it still smokes, has had a few spots on her lungs and is still going strong - they couldn't confirm or deny it was cancer but she is at this point in good health two years out.
?
See the onco I dr.

And good luck.. Hugs!
