Hey, I am 19 years old and I was wondering how likely it is for someone in my situation to have colon cancer. I have a great grandparent on my mother and fathers side who have had colon cancer. I have for the past 4 or 5 months have been noticing blood in my stool. At first I ignored it mostly because I found it embarrasing to talk to anyone about. Recently I have noticed the bleeding to be heavier. I've also felt extreamly tired for the past couple months, sleeping over 14 hours a day sometimes. I have constant stomach pains and find myself feeling like I have to go to the bathroom almost constantly. Only that when I try to go I find myself constapated. Can someone please offer me some advice and information?
