Hello all

I am 18 and live with my grandmother after losing both my parents to cancer within two years of each other.

my grandmother went in for a colonoscopy on the 20th of December and today she received a letter asking to attend an appointment on the 19th at general surgery. 

I was young when i lost my parents so don't know if this is the norm for getting results or if it means they have found something and this appointment is to discuss surgery? 
My grandmother is an extremely strong character but I know this may sound selfish but i don't think i could cope with losing someone else to this awful disease. 
 

does anyone have any experience with colonoscopy results? Am i just thinking the worst? 
i can't stop crying and my anxiety is driving me to breaking point. It's also making me feel guilty as my grandmother is so calm (in the outside anyway) it's making me think I'm just selfish.

any help you can give would be greatly appreciated
