Blood in Stool

Im a 19 year old male and was wonder what it means to have bright red blood in poop.  A couple weeks ago I had some diarrhea and then after going several times, the last few a few drops of red dripped into the toilet and were on the toilet paper.  Then everything was fine for a few weeks, until I go diarrhea again, and saw just  a little red.  Now I'm constipated.  Does anyone have any ideas on what could be causing this.  I keep reading online and everything points to colectoral cancer and that makes me really nervous, event though Im so young.  Any advice would be GREAT!

Thanks to anyone who helps

Blood in your stool can be worrisome .... first off, can it be a case if irritated hemmorhoids, those can bleed a little if you strain too much on the bowl.  Eventhough, active bleeding - bright red blood - should be checked out especially if it's happening more than once.  Most probably nothing to worry about but check it out to be safe.  Good luck
