I am an 18 year old female and very scared. So for a little less than a month I have been having been have blood in my stool. I am awaiting my colonoscopy but am freaking out because I still have a week and a half until that. I do have a family history of colon cancer including my great grandma, two great aunts, my dads cousin, and my aunt who passed away at age 37 of colon cancer. I already had a fecal occult blood test done and it came back positive. I am curious to what others think??
