Could persistent blood in stool for seven to eight years be a sign of colon cancer?

Possible Causes of Prolonged Rectal Bleeding for Seven to Eight Years

Prolonged rectal bleeding for seven to eight years could indicate colorectal cancer, but it may also signify other conditions such as hemorrhoids, anal fissures, rectal polyps, or ulcerative colitis. Here are the possible explanations:

1. Hemorrhoids

Prolonged rectal bleeding, particularly bright red blood dripping after bowel movements, is often attributed to ruptured hemorrhoids, which typically accompany pain during defecation. It is recommended to promptly adjust lifestyle and dietary habits. In severe cases, treatments like Musk Hemorrhoid Suppositories or Puji Hemorrhoid Suppositories may be prescribed under medical supervision.

2. Anal Fissures

When the skin layer of the anal canal tears and forms ulcers, it can lead to rectal bleeding accompanied by anal pain and constipation. Local treatments like Lincomycin Lidocaine Gel or Erythromycin Ointment may be administered upon a doctor's advice. In severe cases, anal dilation surgery may be necessary.

3. Rectal Polyps

Rectal polyps are pathological changes on the surface of the rectal mucosa. Defecation can irritate and cause bleeding from polyps, usually appearing as bright or dark red blood. Vitamin K4 Tablets or Carbazochrome Tablets may be prescribed for hemostasis. Surgical removal may be necessary in severe cases.

4. Ulcerative Colitis

This chronic, non-specific intestinal disorder is characterized by intermittent diarrhea, accompanied by mucus-containing bloody stool and abdominal pain. Treatments like Olsalazine Sodium Capsules or Mesalazine Enteric-coated Tablets may be prescribed under medical guidance.

5. Colorectal Cancer

Some colorectal cancer patients experience rectal bleeding due to friction between stool and tumor tissue. This is often accompanied by mucus and symptoms like malnutrition and weight loss. Early-stage cancer patients may undergo surgical resection, while those in advanced stages may require radiotherapy and chemotherapy.

Persistent rectal bleeding for seven to eight years can have multiple causes. If symptoms persist, prompt medical diagnosis and treatment are crucial. Additionally, adopting healthy habits like increasing dietary fiber intake, avoiding sedentary lifestyles, and actively preventing constipation can help prevent such issues.
