Reading the follow up comments, I wanted to add- definitely be supportive but not too assertive. I have a very strained relationship with my small family and did not involve them in any way (they did not even know I had cancer until I had good news after treatment) which is why having a friend is so valuable. She can also get a “buddy” through the Colorectal Alliance- someone who has gone through it so they are familiar with the process.

You could also (if possible) try to visit, but do not offer unless it is something you can do. Minnesota is lovely in the summer and fall.
