Good morning ~ I believe you can take a deep breath and relax about this one! If this was a radiation appointment for treatment, I would try not to miss it, but your follow ups shouldn't involve anything vital to your recovery other than good advice , etc. I went to my lumpectomy in January 2017 in a snow storm and then again an axillary node dissection! Those 2 things I wouldn't miss, I'd gotten myself worked up enough to postpone! This is an interesting time in your recovery. sOme people say they miss the people they became friendly with during various treatments ~ In your case radiation~ and actually feel a let down when it's no longer necessary to show up each day for their treatments! I had 7 weeks of radiation and I DID kind of miss that routine; I felt that the treatments were important to my recovery and I enjoyed becoming friends with the other people in the "gowned" waiting room. One gentleman was a ray of sunlight, so funny and upbeat. We called him "Dennis the Menace"! SO, there are some random thoughts on my experience. 2 years cancer free, 1 year, 8 months into Arimidex. Time marches on! Best of luck!
