Colon Cancer
Colon Cancer
Colon cancer is one of the most common cancers worldwide, affecting the colon (large intestine), which plays a vital role in absorbing water and forming stool. The disease usually develops slowly and often begins as small, benign growths called polyps on the inner lining of the colon. Over time, some of these polyps can undergo changes and become cancerous if not detected and removed early.
Thanks to advances in screening, diagnostics, and treatment, colon cancer is highly treatable, especially when diagnosed at an early stage. Dr. Anadi Pachaury, a highly experienced Surgical Oncologist, specializes in the comprehensive diagnosis and management of colon cancer, offering patients personalized, evidence-based treatment with a strong focus on long-term health and quality of life.
What Is Colon Cancer?
Colon cancer is a type of colorectal cancer that arises from the lining of the colon. Most colon cancers are adenocarcinomas, originating from glandular cells that produce mucus to lubricate the bowel. The disease often develops gradually over several years, progressing from normal tissue to polyp formation and eventually to cancer.
Because colon cancer can remain asymptomatic in its early stages, regular screening plays a crucial role in early detection and prevention.
Causes and Risk Factors of Colon Cancer
The exact cause of colon cancer is not always known, but several genetic, lifestyle, and medical factors can increase the risk:
Lifestyle Factors
- • Diet high in red or processed meats
- • Low fiber intake
- • Physical inactivity
- • Obesity
- • Smoking
- • Excessive alcohol consumption
Medical Conditions
- • Inflammatory bowel disease (ulcerative colitis, Crohn’s disease)
- • Type 2 diabetes
Genetic and Family History
- • Family history of colon or colorectal cancer
- • Familial Adenomatous Polyposis (FAP)
- • Lynch syndrome
Dr. AnadiPachaury emphasizes risk assessment, lifestyle modification, and early screening, especially for individuals with a family history or chronic bowel conditions.
Symptoms of Colon Cancer
Colon cancer symptoms may vary depending on the tumor’s size and location. In early stages, symptoms may be mild or absent. As the disease progresses, common symptoms include:
- • Changes in bowel habits (diarrhea, constipation, or narrowing of stool)
- • Persistent abdominal pain or cramping
- • Blood in the stool or rectal bleeding
- • Unexplained weight loss
- • Fatigue and weakness
- • A feeling of incomplete bowel emptying
- • Anemia due to chronic blood loss
Because these symptoms can overlap with common digestive issues,persistent or unexplained symptoms should never be ignored.
Diagnosis of Colon Cancer
Accurate diagnosis and staging are essential for successful treatment planning. Diagnostic evaluation may include:
1. Colonoscopy
The gold standard test that allows direct visualization of the colon and removal or biopsy of suspicious polyps.
2. Biopsy
Confirms the presence and type of cancer.
3. Imaging Studies
- • CT scan of the chest, abdomen, and pelvis
- • MRI in selected cases
- • PET-CT for advanced disease
4. Blood Tests
Including tumor markers such as CEA (Carcinoembryonic Antigen).
Dr. AnadiPachaury follows a multidisciplinary approach, working closely with gastroenterologists, radiologists, pathologists, and medical oncologists to ensure precise staging and optimal treatment planning.
Stages of Colon Cancer
Colon cancer is staged from Stage I to Stage IV, depending on tumor depth and spread:
- • Stage I: Cancer confined to the inner layers of the colon
- • Stage II: Cancer extends through the colon wall
- • Stage III: Spread to nearby lymph nodes
- • Stage IV: Spread to distant organs such as the liver or lungs
The stage of cancer plays a key role in determining treatment options and prognosis.
Treatment Options for Colon Cancer
Colon cancer treatment typically involves a combination of therapies, tailored to the stage of disease, tumor location, and patient’s overall health.
1. Surgery for Colon Cancer
Surgery is the primary treatment for colon cancer, especially in early and locally advanced stages. The goal is to remove the cancerous segment of the colon along with surrounding lymph nodes.
Common surgical procedures include:
- • Partial colectomy (segmental resection)
- • Hemicolectomy
- • Extended colectomy for advanced disease
Dr. AnadiPachaury specializes in advanced colon cancer surgery, using both open and minimally invasive techniques to achieve complete cancer removal with minimal impact on bowel function.
Colon cancer treatment typically involves a combination of therapies, tailored to the stage of disease, tumor location, and patient’s overall health.
2. Minimally Invasive (Laparoscopic & Robotic) Surgery
Modern surgical techniques allow many colon cancer surgeries to be performed using laparoscopic or robotic approaches, offering several advantages:
- • Smaller incisions
- • Reduced postoperative pain
- • Faster recovery
- • Shorter hospital stay
- • Better cosmetic outcomes
With extensive experience in advanced minimally invasive oncology surgery, Dr. Pachaury selects the most appropriate approach for each patient.
3. Chemotherapy
Chemotherapy may be recommended:
- • After surgery (adjuvant therapy) to reduce recurrence risk
- • Before surgery (neoadjuvant therapy) in select cases
- • For advanced or metastatic colon cancer
Chemotherapy helps eliminate microscopic cancer cells and improve long-term survival.
4. Radiation Therapy
Radiation therapy is less commonly used for colon cancer but may be considered in:
- • Advanced disease
- • Tumors invading nearby structures
- • Palliative settings to relieve symptoms
Multidisciplinary and Personalized Care
Colon cancer management requires a team-based approach. Dr. AnadiPachaury collaborates with medical oncologists, radiation oncologists, nutritionists, and rehabilitation specialists to ensure comprehensive cancer care.
Each patient receives a personalized treatment plan, taking into account:
- • Cancer stage and biology
- • Patient’s age and overall health
- • Functional and lifestyle considerations
Recovery and Post-Treatment Care
Recovery after colon cancer treatment depends on the extent of surgery and additional therapies.
Post-treatment care includes:
- • Pain management
- • Gradual return to normal diet
- • Nutritional counseling
- • Monitoring bowel function
- • Regular follow-up visits and imaging
Patients undergoing chemotherapy may require several months of treatment, along with close monitoring for side effects. Long-term follow-up is crucial to detect recurrence early and maintain overall health.
