Having the lymph nodes affected is bad, but at least it hasn't gotten to his liver (typical with lung cancer).
Dad said they took pictures. One of his healthy lung and one of the affected lung and the tumor.
I asked "What's it look like, A big scary monster?"
He said "Yea".
"Well, let's kill the fucker".
