It's as the title says. I'm 25 years old and there was dark red blood on the tissue after wiping. Quite a lot of it, too. I sent in a stool sample to the doctors about a month ago due to having problems with constipation/cramps and mucus, and they didn't find anything in that. I don't have hemorrhoids that I'm aware of, so I'm very, very convinced that this is it. I've spent years worrying about cancer and now it's actually happening to me.
