answer:I want to show him he’s still heathy just in other ways. Anyone have ideas of certain activities that are safe for Cancer patients? Careful. Your friend probably won’t appreciate being dragged around to do activities that he will probably find more tiring than fun. I think the best thing you can do for him is spend time with him talking, if he wants to talk, and doing low-key activities. Not sure how old you are or what his interests are but some suggestions are video games, board games, spending time sitting outside, arts and crafts. I have not known anyone with this specific type of cancer, but through my own experiences with illness in general, I suspect I am right.
