So sorry for your wife. If you do make plans then do purchase travel insurance. I was able to travel after a mastectomy/lymph node involvement. My kind doctor coordinated my chemo treatments with a clinic in another state so I could travel. Later, I flew to Mayo for a breast expander/implant and flew back home to Fairbanks,AK. All went well. However, please encourage your wife to not do this. I insisted and everyone accommodated me. In retrospect, I know I would have fully recovered so much more quickly if I had stayed home. It was a really long time before I felt like I had any energy. Again, in retrospect, not worth it. Your wife does not have to be a super woman and carry on as though this is an everyday occurrence. It isn't. Acknowledging that truth is great. Stay home and you, husband, take your family vacation at home with her. Make everyday special. A year from now she, and you, will be glad you did. Best wishes.
