1 Rectal bleeding is the passage of blood through the anus. 2  Rectal bleeding may be red, maroon, black, or occult. 3  The common causes of rectal bleeding include anal fissure, hemorrhoids, diverticulosis, colon cancer and polyps, post-polypectomy, angiodysplasias, colitis proctitis, and Meckel's diverticula.
Most likely, the blood in your stool - something doctors call hematochezia - is related to a less serious condition. However, if bleeding is cancer-related, colorectal cancer and anal cancer are two types of cancers that can cause rectal bleeding or blood to be present in the stool.
