What is Rectal Cancer: Causes & Symptoms

Rectal cancer is a type of cancer that originates in the rectum, the final portion of the large intestine, where the body stores stool before elimination. This condition is one of the most common types of cancer affecting the gastrointestinal tract, yet it remains a subject many hesitate to discuss. Raising awareness about its causes, symptoms, and treatments can make a world of difference in early detection and successful recovery.

If you or a loved one is concerned about rectal cancer, understanding its causes and symptoms is the first step toward managing it effectively. Here, we’ll also discuss advancements in rectal cancer care and the importance of consulting specialists like Dr. Durai Ravi, a renowned laser and laparoscopic surgeon specializing in gastrointestinal disorders.

What is Rectal Cancer?

Rectal cancer occurs when abnormal cells grow uncontrollably in the tissues of the rectum. These cells can form tumors, which may eventually spread to nearby organs and other parts of the body if untreated. While rectal cancer shares similarities with colon cancer, its location presents unique challenges and requires tailored treatment approaches.

What is the Most Common Cause of Rectal Cancer?

While there is no single cause for rectal cancer, several factors can increase the risk:

  • Dietary Habits: A diet high in red and processed meats and low in fiber can contribute to rectal cancer development.
  • Family History: Genetic predisposition plays a significant role. Conditions like Lynch syndrome or familial adenomatous polyposis (FAP) elevate the risk.
  • Chronic Conditions: Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, can damage the rectum’s lining over time.
  • Lifestyle Choices: Smoking, alcohol consumption, and obesity are significant risk factors.
  • Aging: Most cases of rectal cancer are diagnosed in individuals over 50, although younger people are increasingly being affected.

How Does Rectal Cancer Happen?

Rectal cancer develops when genetic mutations in the cells of the rectum cause them to grow uncontrollably. These mutations may occur due to:

  • Environmental Triggers: Long-term exposure to harmful substances in food, air, or water.
  • Chronic Inflammation: Persistent irritation or damage to the rectal lining.
  • Genetic Factors: Mutations passed down through families that increase susceptibility.

Over time, these changes can lead to the formation of polyps, small growths on the rectal lining. While most polyps are benign, some can evolve into cancer if left untreated.

What Were Your First Signs of Rectal Cancer?

Early detection of rectal cancer often hinges on recognizing its initial signs, which may include:

  1. Blood in the Stool: A common but often overlooked symptom. Blood may appear bright red or dark, depending on its source.
  2. Changes in Bowel Habits: Persistent diarrhea, constipation, or a feeling that the bowel does not empty completely.
  3. Unexplained Weight Loss: Losing weight without any dietary or lifestyle changes.
  4. Abdominal Pain or Discomfort: Cramping or a feeling of fullness in the abdomen.
  5. Fatigue: Chronic tiredness due to anemia from blood loss.

If you notice any of these symptoms, it is crucial to consult a colon and rectal doctor promptly. Early intervention can significantly improve outcomes.

Symptoms of Rectal Cancer

In addition to the early signs, more advanced symptoms may include:

  • Narrow stools, often described as pencil-thin.
  • Persistent rectal bleeding.
  • A noticeable lump near the rectum.
  • Difficulty in passing stools or feeling pressure in the rectum.

These symptoms underscore the importance of regular screenings, especially for individuals with risk factors or a family history of colorectal cancer.

How to Avoid Rectal Cancer?

Prevention is always better than cure. Here are some effective ways to lower your risk:

  1. Adopt a Healthy Diet: Increase your intake of fruits, vegetables, and whole grains while reducing red and processed meats.
  2. Stay Active: Regular physical activity helps maintain a healthy weight and reduces cancer risk.
  3. Avoid Smoking and Limit Alcohol: These habits significantly elevate the likelihood of developing rectal cancer.
  4. Routine Screenings: Colonoscopies and other diagnostic tests can detect polyps early, preventing them from becoming cancerous.

Consulting an experienced professional like Dr. Durai Ravi ensures personalized advice tailored to your medical history and lifestyle.

Diagnosis of Rectal Cancer

Diagnosing rectal cancer involves several steps:

  • Physical Examination: Includes a digital rectal exam (DRE) to feel for abnormalities.
  • Colonoscopy: A gold-standard test where a camera examines the colon and rectum for polyps or tumors.
  • Imaging Tests: CT scans, MRIs, and ultrasounds provide detailed images of the rectum and surrounding tissues.
  • Biopsy: A tissue sample is taken to confirm the presence of cancer.

An accurate diagnosis lays the foundation for determining the best treatment for rectal cancer tailored to the patient’s condition.
