@joy345, I have been asking the Microsoft Bot all kinds of questions since the program emerged. I wonder if it can get annoyed! Anyway, here is what I asked it after reading your dilemma: "If someone with tonsil cancer has doctor # one suggesting high-dose radiation and doctor # two suggesting a lower dose saying it is probably HPV related, which should person choose?" Here is the answer the AI gave: " Both high-dose radiation and lower dose radiation are used to treat tonsil cancer. However, researchers are studying whether people with HPV-related tonsil cancer can be treated with lower doses of radiation and chemotherapy. This less intense treatment causes fewer side effects and, in early studies, seems to be as effective as higher doses. It is best to consult with your doctor to determine which treatment is best for you."
Perhaps a third opinion may be something you and your husband could do if affordable/allowed by insurance.
Indecision seems to be a part of this journey. The best advice this mere human can give is to pray to our wonderful God for signs as to which direction to take. It sounds as though you already know that! I pray you and your husband have peace in your hearts and wisdom in your minds.
