Well, you aren’t dead yet. Actually you seem to be reeling with a new diagnosis but not yet a battle plan. Leave room for that in your head while you & your dear wife adjust to the facts as you learn them.
Could I offer you a bit of advice, unsolicited tho it may be?
..Until you learn the details from your medical team about yourself & your particular cancer, avoid research & advice from armchair/internet doctors, even well-meaning ones like your FRiends here. Don’t waste time investigating treatments/outcomes you may never undergo. Just plain don’t waste time. Conserve your energy. Prioritize your time.
I’m keeping you & your wife on my heart.
Good advice, stay away from the symptom search engines and all that.
Listen to your Dr’s and if needed seek 2nd opins.
Good luck
