Iam so sorry to hear about your sister's difficulty with getting chemo. You are doing everything you can for her just by being there for her and showing her you love her. I think you need to have a discussion with her doctor and weigh the pros and cons of chemo. Comfort is the most important thing for your sister at this time. I will keep you both in my prayers.
My beautiful daughter, Lauren Patrice, will live on in my heart forever.
My comments, suggestions, and opinions are based on my experience as a caretaker for my daughter, Lauren and from reading anything I can get my hands on about Cholangiocarcinoma. Please consult a physician for professional guidance.
