What is Colorectal Cancer?

Colorectal cancer develops in the colon or rectum. It typically begins as non-cancerous growths called polyps, which, over time, can become malignant. Colorectal cancer is one of the most common cancers, but early detection can significantly improve outcomes.

Common symptoms include persistent changes in bowel habits, rectal bleeding, abdominal pain, and unexplained weight loss. However, many cases in the early stages show no symptoms, which makes timely and regular screenings all the more important.

Screening Methods for Colorectal Cancer

Screening is a preventive measure aimed at detecting cancer before symptoms appear, improving the chances of successful treatment. Several methods are available:

Colonoscopy

A colonoscopy is considered the gold standard for colorectal cancer screening. This procedure involves using a flexible tube with a camera to examine the colon and rectum for abnormalities. If polyps or suspicious growths are detected, they can often be removed during the same procedure. Recommended for individuals aged 50 and above, or earlier for those with a family history of colorectal cancer, colonoscopy provides the highest accuracy in detecting and preventing cancer.

Stool-Based Tests

These non-invasive tests check for blood or DNA changes in the stool, which may indicate colorectal cancer or polyps. Common types include:

  • Faecal Immunochemical Test (FIT): Detects hidden blood in stool samples
  • Stool DNA Test: Identifies genetic markers associated with cancerous changes

Stool tests are convenient and can be done at home, but they may require follow-up colonoscopy if results are positive.

Barium Enema

A barium enema is an X-ray procedure that uses a liquid contrast to outline the colon and rectum. While less commonly used today, it can help identify abnormalities such as polyps or tumors. It is less detailed than a colonoscopy and usually serves as an alternative when other methods are unsuitable.

Treatment Options for Colorectal Cancer

If colorectal cancer is diagnosed, the treatment will depend on the stage and location of the cancer, as well as the patient’s overall health. Common treatment methods include:

Surgery

Surgery is the primary form of treatment for most cases of colorectal cancer. It aims to remove cancerous tissue and nearby lymph nodes to prevent further spread.

Chemotherapy

Chemotherapy involves the use of drugs to kill cancer cells or slow their growth. It is often used alongside surgery, particularly for advanced-stage cancer or when cancer has spread beyond the colon or rectum.

Radiation Therapy

Radiation therapy uses high-energy rays to target and destroy cancer cells. It is commonly used for rectal cancer, either before surgery to shrink tumors or after surgery to eliminate remaining cancer cells.

Targeted Therapy and Immunotherapy

These advanced treatments involve drugs that specifically target cancer cells or help the immune system recognize and attack them. They are usually reserved for metastatic or treatment-resistant cancers.

Colorectal Cancer Surgery: What to Expect

The type of surgery depends on the location and extent of the cancer:

Polypectomy and Local Excision

For very early-stage cancers or precancerous polyps, these minimally invasive procedures may suffice. A colonoscope is used to remove polyps or small tumours directly.

Colectomy

A colectomy involves the removal of part or all of the colon. It is further categorized into:

  • Partial Colectomy: Only the cancerous section of the colon is removed, along with surrounding healthy tissue.
  • Total Colectomy: The entire colon is removed, typically reserved for conditions like extensive cancer or hereditary conditions like familial adenomatous polyposis.

In both cases, the surgeon will reconnect the healthy parts of the digestive system afterwards, if possible.

Rectal Cancer Surgery

Rectal cancer may require more complex surgery, such as:

  • Low Anterior Resection (LAR): Removes the diseased part of the rectum while preserving the anus.
  • Abdominoperineal Resection (APR): Removes the rectum and anus, requiring a permanent colostomy.
