Hi I was diagnosed With anal cancer six weeks ago and I am looking for advice from anyone that has had papilion treatment or anyone that has information on it .I am awaiting an appointment .The hospital I am at have advised a Colostomy bag and seem anti papillon treatment but would still like to explore this option. 

Many advice would be appreciated and any one who has had it good or bad out comes .Just need some opinions ...feeling a bit lonely and scared as hell .
