Haemorrhoid blood in the stool is bright red blood in the stool, mostly in the form of spraying bleeding, which is more pronounced during bowel movements and stops bleeding afterwards. In colon cancer, blood in the stool is mostly dark red, accompanied by pus and often mixed with stool, and may be accompanied by changes in bowel habits, a feeling of incomplete defecation and constipation. It is important to note that blood in the stool in rectal cancer may present as fresh blood, which can easily be mistaken for bleeding from haemorrhoids.
