Welcome, I am glad you found us.
We have members here that have had multiple family members with this diagnosis. Connie B is a friend of mine and she lost her mother , father and sister to lung cancer then she was diagnosed at 43. Since then others like aunt etc have also been told that they have lung cancer. In some families it seems to hit hard.
Please let us know how he is doing. Remember some of us do survive. I am cancer free, and a 11 year survivor.
