Hi Sharon,
I'm sorry you had to join this site but it will be very beneficial to you and your brother. It is hard to say how his recovery will go; we would need to know much more information about the primary site of the tumor, the size, any lymph node involvement, Chemo and Radiation plans, etc., as everyone's story is different. The most important thing right now and until he is unable to anymore, is that he eat everything that looks or sounds good. Forget the calories! Have his doctors mentioned him needing a PEG tube? A lot of OC patients end up needing this device because it becomes very difficult to eat or even drink. My husband had a PEG and still lost 60 pounds during his first treatment. Will you be your brother's main caregiver? It is a hard job, but he truly will need someone to go to appointments with him, and physically help him with his symptoms, medications, etc. I'm sure you will get more good advice from many others here. Ask any questions you may have and someone will answer. We are here for you.
Lori
