What color is the blood in the stool caused by rectal cancer?

When the tumor invades the mucosa, the amount of bleeding is generally small, and it mainly appears dark red or bright red. The blood covers the back surface. The bleeding is indirect and not easy to attract people's attention. It is often thought to be caused by hemorrhoids. The color of blood in the stool of rectal cancer is dark red, and it often adheres to the stool. It is also accompanied by an increased frequency of bowel movements and a feeling of falling in the anus. In other words, the feces discharged by the patient contains pus and blood. The blood looks relatively thin. If it is pus and blood in the stool or bloody stool containing mucus, it should be a manifestation of rectal cancer.

What are the symptoms of rectal cancer?

1. Long-term constipation

Long-term constipation can also cause stool to remain in the body, resulting in higher and higher concentrations of carcinogens. If the colon wall is in contact with these carcinogens for a long time, it will slowly turn into rectal cancer or colon cancer.

Changes in bowel habits

If your bowel movements are usually dry but suddenly become very loose, or if your very loose stools become very dry, your bowel movement habits may also become abnormal, from once a day to twice or three times a day.

2. Abdominal pain

20% of patients with rectal cancer will experience abdominal pain in the early stages. This is because the upper rectum becomes narrow and intestinal obstruction occurs, resulting in paroxysmal abdominal pain accompanied by abdominal distension, bowel sounds, loose and soft stools, and reduced anal flatus. These conditions can only be relieved or disappear after defecation.

3. Feeling of heaviness and swelling in the perineum

When the rectal cancer tumor grows larger or invades the surrounding tissues, it is often accompanied by a feeling of heaviness in the perineum, a feeling of incomplete defecation, and a falling anus. A large amount of secretions will flow out of the anus, and there will be pus and blood.

How to prevent rectal cancer?

1. Pay attention to diversity in diet and develop good eating habits. Do not be picky or partial in food. Do not drink high-protein and high-fat foods for a long time. Eat more fresh vegetables and fruits containing dietary fiber and vitamins. This can better prevent rectal cancer.

2. Develop a good habit of regular bowel movements to prevent constipation. Actively treat anal fissures, anal fistulas, rectal polyps and chronic intestinal inflammation. Once rectal cancer is discovered, you should choose a regular hospital for surgical removal in time to prevent cancer.
