Things I used (chemo for breast cancer) :
Oral antibacterial wash
I hated my wig (a.k.a. "the hairy hat") and had funky scarves made in 21-
inch squares - wore them pirate-style (bandannas didn't cover the whole head, I didn't like the premade wraps, and I though caps were itchy...picky me...)
Often quite difficult to eat, even with antinausea drugs, from days 2-5. Don't assume anything about what she will be able to tolerate (no offense to anyone with suggestions - but I tried to stock up beforehand on what I thought would work...and nothing!! For me, I could only eat plain oatmeal, gross - the saltines sat in my cupboard!!). OH, and PS - the things I ate right before or after chemo STILL make me want to throw up three years later. Tell her not to eat any of her favorites at that time unless she's willing to find new ones...
For chemo sessions - board games, books, YOUR PRESENCE. My mom came up and visited for each session, played board games with me, and acted like I was just having a long (but normal) dr's appointment. It helped me so much to feel relatively normal, I can't even tell you.
Books were lovely. I found Lance Armstrong's to be very inspiring.
And again - YOU. Your presence. Let her know that you are there to help her and love her, and let her know that YOU see her as normal when everyone else in the world (feels like) is looking at her head.
I wish her and you the best. Cancer/chemo are lifechanging events, but I came out with a Carpe Diem thing that has made my life better - I'll never say that I was lucky to go through it, but my life is better now for what I learned. I am three years out of bc...but my coworker's mom is a 12 year survivor of ovarian cancer.
She can do it. Many, many people are now pulling for her on this board. Hugs to you both.
