Yest my bowel was really hard and today saw a little blood in bowl. could i have hurt myself? 41 yrs old no fam hist of colon cancer.

Not normal: Blood in the stool is not normal and needs to be explained. Causes include local irritation, anal fissure ( crack in the tissue) hemorrhoid, polyp, inflammation( colitis ) and cancer. You will need to see a health care provider to get a diagnosis. A family history negative for colon cancer is good but does not exclude the possibility of cancer
