Adam,
I, too, have been struggling with a father in late stage lung cancer. How painful to watch our parent reduced to such a vulnerable state...and going thru so much pain.
Yesterday I posted a note asking for others who might have survived this late stage lung cancer - for encouragement for my dad. Today...he got the astounding news from his doctor that his cancer is undetectable. After radiation & chemo for 2 months, they see no sign of tumors. His had also metastasized to the spine, lymph nodes, chest cavity, etc...
There is hope! We put him on an immune boosting program (after MUCH research on my part). Check out polymva.com or polymvasurvivors.com. It's a liquid that my dad went on for 1 month...and saw the tumors disappear. We also got him on "immunopower" which is recommended by the book "fighting cancer through nutrition." Immunopower is simply packets of supplements & powder taken daily -also to enhance the immune system. I can't say for sure whether these things are what did the trick...but there are many out there who have survived cancer after taking them.
Anyway, the biggest message is...keep the faith. God is full of surprises. He just may be saving one for your dad.
Blessings in Him,
Shawna
