New - dad has aggressive Iung cancer

I am so sorry to hear that.  I was diagnosed with small cell lung cancer and already had a few tumors in my brain.  They had me in the hospital the very next day and doing chemo.  I have done three rounds of chemo now(12 total days).  I started back in July.  I had a 9 cm tumor on my lung.  I am so sorry they don't feel like that is an option for your dad.  My father-in-law had cancer and they only gave him a few months.  He lived for eight more years.  I will pray your dad has many months to spend with you.
