What to do for a friend having a Double Mastectomy?

We’re casual friends, not particularly close. She’s 44 and her husband works from home so her 2 children (10 & 12) will be cared for (and her Mother is now staying with them). There are already meals scheduled for the next three weeks. I’d like to make a gesture that will be specifically for her well being and care, although I am not clear on what her mobility or pain level will be like. Does anyone have any insight and/or suggestions? Thanks!
