“It’s late stage. It’s advanced lung cancer. But there’s good news associated with the diagnosis and the treatment.”
Doesn’t sound from that like he is ready to throw in the towel.
Cancer is deeply personal and every sufferer, and their family will react differently. My mother is a survivor, her odds were good... Ive also known people who were terminal cases, and those who go the route of palliative care, as opposed to fighting it tooth and nail, seem to suffer less in the long term. That’s only from my limited personal experience.
