Oh gosh, lots of love and prayer to your friend. Bless you for being there to support her.

My Mum had much the same happen in 2005, and FWIW, she is a 6 year survivor now, so there is hope. Your friend will need plenty of support. She will be sore from the op and then sick from the chemo and radio. Just being there to help her with the day to day stuff will be so important. All the stuff listed above will be awesome. Obviously the kids will need feeding but don't necessarily go overboard cooking for her once chemo starts. I can't count how many sao & vegemites I did for Mum during her treatment

A tip for chemo induced mouth ulcers - the baking soda toothpaste does wonders. Mum swore by it.

All the best to you and your friend xox
