I would like to add to this, from things I have learned as a cancer caregiver. I have found it VERY helpful to take pictures of any important documents (doctor business cards, port identification cards, stent information, suggested diet, etc). I made a folder on my phone for medical information for my husband and I keep it all in there at the tip of my fingers). I have found a notebook, as mentioned, very helpful for recording symptoms and what my husband was eating while recovering from the surgery and during chemo and radiation. I also record any blood pressure, temperature or pulse oxygen I take in there. That way I don’t forget what has happened if I am asked.
