I'm 18 years old, and I'm afraid I might have colon cancer. For 2 days now I've been having pain in my rectum, and it also feels heavy(rectum) even after I use the restroom. On friday I was constipated, it went on till saturday, then saturday night my rectum started to feel really heavy, so I used the bathroom, and I was still a little bit constipated, so I drank some prune juice. On sunday, my stool came out normal except that I started having rectum pain right after, it hurts to even sit. And today my stool came out really small and narrow. Theres no blood in there though. So could this be colon cancer? :-( Btw before these 2 days, I was fine, I just having these symptoms on saturday.
I'm also feeling weak and dizzy but that could just be that I'm getting my period soon.
