Could bowel movements without blood indicate bowel cancer?

Bloodless bowel movements can be indicative of colon cancer, but they can also stem from diseases such as hemorrhoids or anal fissures. It is recommended that patients promptly seek medical attention and undergo treatment under the guidance of a physician.

1. Colon Cancer

Colon cancer refers to cancer occurring in the rectum and colon, which may be linked to genetic factors or result from poor dietary habits. Tumor cells stimulate the intestine, leading to changes in bowel movements, such as narrower stools and increased frequency, accompanied by a sense of incomplete evacuation and blood in the stool. Surgical resection can be performed under the guidance of a physician.

2. Hemorrhoids

Hemorrhoids are a common anorectal condition with an unclear etiology, though prolonged sitting and prolonged bowel movements are considered contributing factors. Symptoms include pain during bowel movements, anal itching, and prolapse, which may also present as the aforementioned conditions. Treatment involves administering drugs like Maren Runchang Pills and Tongbianling Capsules as prescribed by a physician.

3. Anal Fissure

Anal fissures are often caused by chronic constipation, prolonged diarrhea, or trauma. They manifest as pain, bleeding, and constipation during bowel movements. Treatment involves administering drugs like Lactulose Oral Solution and Maren Runchang Pills as prescribed by a physician.

4. Other Diseases

Conditions like ulcerative colitis and Crohn's disease can also lead to similar symptoms. Ulcerative colitis, whose etiology involves environmental and genetic factors, presents with abdominal pain, mucous bloody stool, and loss of appetite. Crohn's disease, a chronic inflammatory granulomatous disease, is associated with infection and genetic factors, causing abdominal discomfort, weight loss, and loss of appetite. Treatment for these conditions involves administering drugs like Mesalazine Enteric-coated Tablets and Sulfasalazine Enteric-coated Tablets under the guidance of a physician.
