Anal cancer

Good morning

I was diagnosed this year with anal cancer. I had chemo radiation for 28 days. 
I have already survived Hodgkin’s disease twice. Breast cancer twice, and had moles removed some of which were cancer but fully excised.

I had an MRI three days ago and waiting to see my oncologist for the results. I admit to being terrified. 
Has anyone has similar experience with anal cancer: how are you now?
