Answer :
Though not all tumors or polyps bleed, occult blood in the stool may be an indication of colon cancer or polyps in the colon or rectum.
What causes occult blood in stool the most frequently?
Small bowel tumors, esophagitis, peptic ulcers, gastritis, inflammatory bowel disease, vascular ectasias, portal hypertensive gastropathy, and colon cancer are a few of the more prevalent causes (eg, GI stromal cell tumor, lymphoma, carcinoid, adenocarcinoma, or polyp)
If the fecal occult blood test results are positive, blood has been discovered in the stool. Your doctor will need to identify the cause of the bleeding, either by doing a colonoscopy or by performing an examination to establish if the stomach or small intestine is the source of the bleeding.
