Hi, I am a 30 year old female. I have twice noticed blood in my stool and on the toilet paper. First time was when I had my period and I thought it may be due to that but now a couple of weeks later it happened again. I also have notice mucus in my stool and when I pass gas. I have no history of colon cancer in my family, though I had a benign polyp removed about 4 yrs ago. I am diagnosed with IBS. I have no weight loss (other way around) but have been very stressed past couple of years. My toilet habits have not changed, I have had no fever. My stool looks normal shape and color (other than mucus and blood). I ma due for an endoscopy and colonscopy soon. But I want to know; is this most likely cancer?
