Daisy,
I'm certain you are feeling very anxious and that's normal. I'm sorry you are going through all of this. My husband had lung cancer. He also had feelings of apprehensions regarding various things they wanted to do. He said no to procedures that he either had bad reactions to or had a negative feeling about doing. He also went along with other things the doctors suggested. What really helped my husband was eating good healthy food and for my husband that was a good healthy steak or roast beef, hamburger, vegetablesand fruit. Prayer also helped him. We prayed daily. My husband lived 14 years with lung cancer before he died at age 83 in 2024.

Pay attention to how you are feeling about the procedure they are suggesting. Remember it's your body and your money. You decide what is to be done to it and when. Take it all to God and he will direct you. I'll say a prayer for you also.
I wish you the best!
