When my mom went through cancer and chemo she had me get her a calendar from the dollar store. She wrote down everything in that thing; what treatments started when, reactions, test results, etc. when the doctors would come in and ask her questions she would hand them the calendar. The doctors said it was very helpful. She also made a Summary list that we both carried around for years after to let doctors know her history. Will keep you busy keeping track and save time! Wish I would have thought of it earlier to tell you..
