Colon cancer is one of the most common cancers, but it is also highly preventable and treatable when detected early. Unfortunately, many people ignore the warning signs, leading to late diagnosis.

In this blog, Dr. Shivam Vatsal Agarwal, Director and Head of Surgical Oncology and Robotic Surgery at Metro Cancer Institute, Faridabad, explains the symptoms, diagnosis, and importance of early detection of colon cancer.

What is Colon Cancer?

Colon cancer begins in the large intestine (colon) and often starts as small growths called polyps on the inner lining. While not all polyps become cancerous, some can develop into cancer over time if left untreated.

Common Symptoms of Colon Cancer

Recognizing early symptoms can save lives. Watch out for:

• Blood in stool (bright red or dark)
• Unexplained weight loss
• Persistent abdominal pain or bloating
• Changes in bowel habits (diarrhea, constipation, narrow stools)
• Fatigue and weakness
• Feeling that the bowel does not empty completely

 These symptoms may be mistaken for piles or indigestion. Always consult a doctor if they persist.

Why Early Detection Matters

Detecting colon cancer early significantly improves outcomes:

• Less invasive treatment options
• Higher survival rates
• Reduced complications

Delaying diagnosis can allow cancer to spread, making treatment more difficult.

Key Diagnostic Tests for Colon Cancer

 1. Fecal Occult Blood Test (FOBT)

Detects hidden blood in stool, which may indicate cancer.

 2. Colonoscopy

The most effective diagnostic tool. A flexible tube with a camera examines the colon and detects polyps or tumors.

3. Biopsy

A tissue sample is taken and tested to confirm cancer.

4. CT Scan / PET Scan

Imaging tests used to determine if cancer has spread to other parts of the body.

Who Should Get Screened?

You should consider screening if:

• You are 45 years or older
• You have a family history of colon cancer
• You have inflammatory bowel disease
• You experience persistent symptoms

Screening can detect precancerous polyps before they turn into cancer.

 Prevention Tips

Reduce your risk with these lifestyle changes:

• Eat a high-fiber diet (fruits, vegetables, whole grains)
• Limit red and processed meat
• Exercise regularly
• Avoid excessive alcohol consumption
• Maintain a healthy weight

 3. Is colonoscopy painful?

No. It is usually done under sedation, so patients feel minimal discomfort.

 4. How often should screening be done?
