I'm so sorry that your husband has lung cancer. My husband also had lung cancer. He never had the radiation treatment but he had chemotherapy and Keytruda. He reacted badly to both and as a result refused treatment of any kind. He lived 14 years with Stage 4 lung cancer. However that doesn't mean that your husband would react badly to cancer treatment. We are all different. However, what really helped us was to read the side effects of the treatments. That way you know what you are dealing with. You can get that information easily on the Mayo Clinic website. Also keep in mind that these treatments are often very expensive and you might want to discuss this with your insurance. The Keytruda treatment that my husband got cost $25,000 per infusion.

There were two things that really helped my husband a lot. One was eating good quality red meat. He loved steak and that protein helped his body fight the cancer. The other was prayer. We prayed together daily and God was there for us. We were fortunate to have those wonderful 14 years together before he died in 2024. With God you can get through anything!

I'll say a prayer for the both of you.
I wish you the best.
