Blood in Stool

I am a 32 year old female, slightly overweight.... I do not have many digestive problems other than heart burn.  Tonight I had a bit of a runny stool with spots of bright red blood. I am really freaking out over it. I will make an appointment to see my doctor in the morning but of course the first thing that comes to mind is Colon Cancer... I have no other symptoms, has anyone else ever experienced this?
Thank you....

While I know it can be difficult, you need to try not to get too upset about this until you know more. You're doing the right thing by following up with a GP. There are many causes for what you've experiencing, and you need to get it checked out. Here's a brief summary of possible causes. As you can see, many of them are NOT cancer:

Causes of Rectal Bleeding

    Anal Fissure
    Colon Cancer
    Colon Polyps
    Crohn's Disease
    Diverticulitis (Diverticulosis)
    Hemorrhoids
    Idiopathic Thrombocytopenic Purpura (ITP)
    Peptic Ulcer
    Stomach Cancer
    Yellow Fever

Seems my doc said I have an internal hemorrhoid that she thinks it is.... :s still scared though and will probably push for a Colonoscopy, it's been 2 years since my last one.  Thank you!
