Donna,
I am so sorry you and your husband are going through this ordeal! That's very hard. My husband had stage 4 lung cancer. He reacted badly to immunotherapy and chemotherapy. In fact, he almost died from both of them. After that experience he stopped all treatments. We just ate healthy and prayed a lot. God was there for us because my husband lived 14 years with lung cancer. He died in 2024. Sometimes your body has just had enough of medications and needs a rest for a while.

It helps to read the side effects of any medication or treatment before your husband gets it. Then you have an idea of what to expect and if you want to try it. You can get that information on the Mayo Clinic website.

I'll say a prayer for both you and your husband.
I wish you the best.
