Had red blood, black stool 3 weeks ago for 3 days. Had hemiglobin and occult test 2 days ago and all normal. This does mean I have no colon cancer?

GI consult, EGD. Limited data available as reported. Colon cancer is rare at such an young age. Bright red blood usually from lower GI tract, or hemorrhoids, fissure etc. However black stoll is concerning for upper GI bleed. Need a GI/Gastroenterology evaluation, EGD/upper endoscopy, H Pylori testing, Upper GI series etc. contact PCP for GI referral. Go to a health tap doctor for a formal consult with more details.
