First off, as others pointed out, your wife is strong enough to handle this, don’t waste energy worrying about her. Just do what you do and love her. Use your energy to support her.

Second: your kids will handle this fine. My mother got cancer when I was 9. The hardest part was seeing my dad cry, and the only other time I saw that was when our dog died. I don’t know how old your kids are, but if it were me, and my family, I would show them that I’m not worried, God has a plan, we have a plan, and we are going to execute the plan, with the help of everyone in the family.

Third: trust your gut. The doctors wanted my mom on radiation and chemo, and she refused the chemo. Decades later, it turned out that the chemo available at that time would have had zero efficacy on the type of cancer she had. She would have poisoned her body for nothing.
