I suspect Dana neglected her own health care while she was caretaker to Chris. This happens a lot. So I don't know if the Lung Cancer was primary, or if it metastasized from else where?
She was an advocate for stem cell research. Kudos to her.

Her advocacy for stem cell reseach in any event, but particularly when adult stem sells have proven to be so much more successful than fetal stem cells was NOT a good thing and in fact was most selfish of her and her husband.
