Oh, we all fear making the wrong decision. But I have learned to say to myself that I am going to make the best decision I can with the information I have and that is all I can ask of myself so, no beating myself up over it. When I decided on my initial rounds of treatment, I used all the latest information I could find, but 18 yrs. later that information is mostly obsolete at worst and inadequate at best. No one’s fault we just know more all the time. Have you or @celica visited any other threads in the breast cancer group? There are several that can be helpful in preparing questions for your doctor. This can really be helpful in decision making.
Do you have a support system of friends or neighbors to help?
