Newly diagnosed with Anal cancer

I went  into hospital on the 16 Feb 2018 to have an anal fissure repaired when I was coming round  they told me they found a lump. I have since had an MRI and CT scan and on 6 March 2018 it was confirmed that I have Anal cancer. Doctor said it was early stages and therefore with Chemo and radiotherapy they should be able to get rid of it.  I go on 16 March for a PET scan and Onocologist appointment on the 21 March.

Apart  from a sore bum as I still have the fissure, physically I feel fine,  I don’t know how can I have this I don’t look ill! I finding it hard to take in.......I suppose this is natural? Mentally I’m all over the place one minute oh it will be alright then down in the dumps again.

Have been scouring the internet for as much information as possible and the hospital gave me a leaflet but I wanted to connect with other people that have this. Can any one help me?
