Understanding Colon Cancer: A Complete Guide for Patients

Colon cancer, also known as colorectal cancer or bowel cancer, is a type of cancer that starts in the colon or rectum, both parts of the large intestine. It’s one of the most common forms of cancer globally, and its incidence is steadily rising in India. Early detection and timely treatment can significantly increase survival rates. This guide will help you understand colon cancer, its symptoms, causes, stages, and the options available for colon cancer treatment in India.

What Is Colon Cancer?

Colon cancer begins when abnormal cells grow in the lining of the colon or rectum. These growths often start as benign (non-cancerous) polyps, which can turn cancerous over time. Regular screening can help detect these polyps before they become malignant.

Common Symptoms of Colon Cancer

Colon cancer can develop without any noticeable symptoms in the early stages. However, as it progresses, some signs may include:

Persistent changes in bowel habits (diarrhea or constipation)

Blood in the stool or rectal bleeding

Unexplained weight loss

Fatigue and weakness

Abdominal discomfort, bloating, or cramps

A feeling that your bowel doesn’t empty completely

If you experience any of these symptoms for more than a few weeks, it is essential to consult a healthcare provider immediately.

Risk Factors

Several factors can increase your risk of developing colon cancer, including:

Age: Most cases occur in people over 50

Family history: Genetics play a role

Lifestyle: Diet high in red/processed meats, smoking, and lack of physical activity

Medical history: Conditions like inflammatory bowel disease (Crohn's disease or ulcerative colitis)

Obesity and diabetes

How Is Colon Cancer Diagnosed?

Early detection is crucial. Diagnostic methods include:

Colonoscopy: The most effective screening method; also used for biopsy

Fecal occult blood test (FOBT): Detects blood in stool

CT Colonography (Virtual Colonoscopy)

Biopsy: If a suspicious growth is found, a tissue sample is analyzed

Blood Tests: Including carcinoembryonic antigen (CEA) levels

Colon Cancer Stages

Colon cancer is categorized into five stages, from 0 (in situ) to stage IV (advanced/metastasized). Treatment depends heavily on the stage of cancer.

Stage 0: Cancer is in the innermost lining.

Stage I–II: Cancer has grown deeper into the wall but hasn’t spread.

Stage III: Cancer has spread to nearby lymph nodes.

Stage IV: Cancer has spread to distant organs, like the liver or lungs.

Colon Cancer Treatment in India

India offers a wide range of treatment options across both government and private hospitals. Treatments are personalized based on the stage, location, and spread of the cancer.

1. Surgery

Surgical removal of the cancerous part of the colon is often the first line of treatment. Options include:

Polypectomy (for early-stage cancers during colonoscopy)

Colectomy (removal of part or all of the colon)

Laparoscopic Surgery (minimally invasive)

2. Chemotherapy

Used to destroy remaining cancer cells post-surgery or to treat advanced cancers. Common drugs include 5-FU, capecitabine, and oxaliplatin.

3. Radiation Therapy

More common in rectal cancer, used before or after surgery to shrink tumors or kill remaining cancer cells.

4. Targeted Therapy

Newer drugs like bevacizumab or cetuximab are used to block specific cancer cell growth pathways.

5. Immunotherapy

Used in certain advanced cases, especially for cancers with genetic markers like MSI-H (microsatellite instability-high).
