Good morning, @kirstine. You’re a very wise sister to urge your brother to see his doctor. Rapid weight loss and pain with eating or drinking, such as he had, should definitely be checked out,
I’m sorry to hear he has cancer. That’s always such a scary word to hear in a diagnosis. His doctors are on top of things though with starting his chemotherapy next week. You mentioned that when he reaches remission it’s been suggested to have a stem cell transplant (SCT). (Also known as a bone marrow transplant (BMT). That procedure would help his body stay in remission. I had a bmt not quite 7 years ago. It gave me a 2nd chance at life and I’m so grateful for that opportunity. So if it becomes available for your brother, it can be positive option. ☺️

I wish him well with the CHOP21 therapy. He may have some days of not feeling on top of the world. But encourage him to push through because there can be better days ahead.
Please let me know how he’s doing along this journey, ok?
