And i am only 16 years old. :-( For about two weeks i have been constipated and i have been having these following symptoms: mucus on my stool, narrower than usual stool( almost pencil like), feeling that i dont empty EVERYTHING. Also, the narrow stools are very hard to push out, which i dont understand because they are so narrow and also look like they have a soft texture to it. I checked my rectum with a mirror to see if i could see anything was blocking the stool and i saw something hot pink.i am really worried because i am only 16 and i am already showing symptoms of colon cancer. Does anyone have an alternative explanation? :'(
