Colon Cancer —
Detect Early. Treat Effectively.
Colon cancer begins in the large intestine and is one of the most preventable cancers when caught early. Expert screening, diagnosis, and treatment by our specialist oncology team at Delhi Cancer Centre.
What is Colon Cancer?
Colon cancer, also known as colorectal cancer, is a type of cancer that starts in the large intestine (colon), which is the final part of the digestive system. It usually begins as small, noncancerous clumps of cells called polyps that can develop into cancer over time.
Detecting and removing these polyps early through regular screening can help prevent cancer from forming altogether. When diagnosed early, colon cancer is highly treatable with excellent survival outcomes.
Symptoms of Colon Cancer
Colon cancer symptoms may not appear in the early stages. As the disease progresses, the following signs may develop:
Note: Early-stage colon cancer often has no symptoms at all. Regular screening colonoscopies — especially for those over 50 or with risk factors — are the most reliable way to detect and prevent colon cancer.
Causes & Risk Factors
Several factors can increase the risk of developing colon cancer:
Age
More common in people over 50; risk increases significantly with age.
Family History
A close relative with colon cancer significantly increases your risk.
Diet
High-fat, low-fiber diets rich in red and processed meats may contribute to colon cancer.
Inflammatory Bowel Disease
Crohn's disease and ulcerative colitis raise the risk of colorectal cancer.
Smoking & Alcohol
Smoking and excessive alcohol use are associated with increased colon cancer risk.
Sedentary Lifestyle
Lack of physical exercise and obesity are significant contributing risk factors.
Genetic Conditions
Lynch syndrome and familial adenomatous polyposis (FAP) greatly increase risk.
Diagnosis of Colon Cancer
Early detection improves survival rates significantly. Common diagnostic methods include:
- Camera-guided examination of the entire colon
- Polyps can be removed during the procedure
- Gold standard for early detection
- Detect hidden blood in stool samples
- Identify abnormal DNA changes
- Non-invasive screening option
- CT Colonography (Virtual Colonoscopy)
- MRI — size, location & spread
- PET Scan — distant metastasis check
- CEA (carcinoembryonic antigen) test
- Tracks cancer progression & response
- Used alongside other diagnostics
- Sample of suspicious tissue analyzed
- Confirms cancer type and grade
- Guides treatment planning
Stages of Colon Cancer
Understanding the stage of colon cancer helps determine the most effective treatment approach and expected outcomes:
Carcinoma In Situ
Abnormal cells are confined to the inner lining of the colon. Highly curable — often treated with simple removal during colonoscopy.
Localized to Colon Wall
Cancer has grown into the colon wall but hasn't spread beyond it. Surgery is highly effective at this stage with excellent survival rates.
Through Colon Wall
Cancer has grown through the colon wall but hasn't yet reached nearby lymph nodes. Surgery remains the primary treatment option.
Lymph Node Involvement
Cancer has spread to nearby lymph nodes. Treatment typically involves surgery combined with chemotherapy to reduce recurrence risk.
Distant Metastasis
Cancer has spread to distant organs such as the liver or lungs. Treatment focuses on controlling the disease and improving quality of life.
Treatment Options for Colon Cancer
Treatment depends on the stage of cancer and the patient's overall health. A multidisciplinary approach ensures the best possible outcomes.
Surgery
The primary curative approach — removing the tumor and surrounding tissue from the colon.
- Polypectomy — for early-stage cancer during colonoscopy
- Colectomy — partial or total colon removal
- Lymph node removal to check for spread
Radiation Therapy
High-energy beams target and destroy cancer cells — often used before or after surgery to shrink tumors or reduce recurrence.
Chemotherapy
Drug treatment used especially for advanced-stage colon cancer or after surgery to eliminate remaining cancer cells and reduce recurrence risk.
Targeted Therapy
Drugs that specifically target cancer cell markers to slow tumor growth — more precise with fewer side effects than conventional chemotherapy.
Immunotherapy
Boosts the immune system to recognize and attack cancer cells. Particularly effective for certain genetic types of colon cancer.
Life After Colon Cancer Treatment
Regular Follow-Ups
Frequent check-ups and imaging tests to monitor for recurrence and long-term health.
Dietary Changes
A high-fiber, balanced diet aids digestion, recovery, and reduces the risk of recurrence.
Physical Activity
Regular exercise helps improve overall health and lowers the risk of cancer recurrence.
Mental & Emotional Support
Counseling and support groups help patients cope with the emotional impact of cancer treatment.
