Colon (Colorectal) Cancer Treatment in Mumbai, India

Colon cancer, also known as colorectal cancer, begins in the colon or rectum, both of which are parts of the large intestine.

Colon cancer usually begins as small growths of tissue called polyps, which can be benign (non-cancerous) initially but may become cancerous over time. These cancerous cells can grow and invade nearby tissues, and if left untreated, they may spread to other parts of the body, a process known as metastasis.

Regular screenings, such as colonoscopies, can aid in early detection and significantly improve the chances of successful treatment. Treatment options for colon cancer may include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, and palliative care, depending on the stage and extent of the cancer. Early diagnosis and appropriate treatment can greatly increase the likelihood of survival and successful management of the disease.

Colon Cancer Symptoms

Colon cancer can manifest with a variety of symptoms, often starting subtly and progressing as the disease advances. It's essential to be aware of these signs and seek medical attention if one experiences them:

• Altered Bowel Habits: Individuals may notice persistent changes in bowel movements, such as diarrhoea, constipation, or a change in stool consistency, lasting for more than a few days or weeks.
• Rectal Bleeding or Blood in Stool: Blood in the stool or bleeding from the rectum, which may appear red or dark, is a concerning symptom and should be evaluated promptly.
• Abdominal Discomfort and Pain: Constant abdominal cramps, pain, or discomfort, including gas, bloating, or feeling full even after a light meal, should not be ignored.
• Unexplained Weight Loss: Significant weight loss without changes in diet or exercise could indicate an underlying issue like colon cancer and necessitate medical attention.
• Fatigue and Weakness: Persistent fatigue, weakness, or a general feeling of tiredness, often associated with anaemia caused by chronic blood loss.
• Iron Deficiency Anaemia: Low red blood cell count due to chronic blood loss from the digestive tract, resulting in fatigue, weakness, and paleness.
• Narrow Stools and Incomplete Evacuation: Stools that are narrower than usual or a persistent feeling of incomplete evacuation during bowel movements could signify a potential obstruction in the colon.
• Gas, Cramps, and Bloating: Frequent gas pain, cramps, or feeling unusually bloated even after passing gas may be indicative of digestive issues, including colon cancer.
• Overall Weakness and Fatigue: Generalised weakness and fatigue that does not improve with rest and affects daily activities could result from the body combating the progression of colon cancer.

Colon Cancer Causes

Colon cancer is influenced by various factors that contribute to its onset and development. Researchers have yet to pinpoint the exact causes of colon cancer. However, they have identified causes that have a significant impact on its development. Here are the key factors associated with the development of colon cancer:

Common Causes of Colon Cancer 

• Age: Advancing age is a primary risk factor for colon cancer. The risk substantially rises after the age of 50, making regular screenings crucial for early detection and intervention.
• Family History and Genetics: A family history of colon cancer or precancerous polyps significantly heightens one's risk. Additionally, certain genetic mutations inherited from parents, like Lynch syndrome and familial adenomatous polyposis (FAP), can predispose individuals to colon cancer.
• Personal History of Polyps or Colorectal Cancer: Individuals with a history of adenomas (precancerous polyps) or previous colorectal cancer have an increased risk of developing colon cancer in the future.
• Inflammatory Bowel Diseases (IBD): Chronic inflammatory conditions of the colon, such as ulcerative colitis and Crohn's disease, are associated with a higher risk due to continuous inflammation and damage to the colon lining.
• Diet and Lifestyle Choices: Consuming a diet rich in red and processed meats and low in fibre, fruits, and vegetables can elevate the risk of colon cancer. A sedentary lifestyle, obesity, tobacco use, and excessive alcohol consumption also contribute to increased susceptibility.
• Diabetes and Insulin Resistance: Individuals with diabetes or insulin resistance face a slightly higher risk of developing colon cancer, although the precise mechanisms linking these conditions are still under investigation.
• Radiation Exposure: Previous radiation therapy, especially in the abdomen or pelvis for treating other cancers, can slightly elevate the risk of colon cancer later in life.
• Environmental Factors: Prolonged exposure to certain environmental pollutants or industrial chemicals may have an impact, although the direct links between environmental factors and colon cancer are still being studied.

Colon Cancer Stages

Understanding the stages of colon cancer is pivotal in determining the extent and spread of the disease, thereby guiding appropriate treatment and prognosis. The stage also plays a crucial role in determining the prognosis and the potential for a successful outcome. Here's an overview of the stages of colon cancer:

Stage - 0 (Carcinoma in Situ):

• The cancer is at its earliest stage, confined to the innermost lining (mucosa) of the colon.
• It has not spread beyond the mucosa and has not invaded deeper layers of the colon.

Stage - 1: 

• Cancer has progressed beyond the mucosa into the submucosa or the muscular layers of the colon wall.
• It has not spread to nearby lymph nodes or distant organs.

Stage - 2:

• Divided into IIA, IIB, and IIC based on the degree of advancement within the colon wall and nearby tissues.
• Cancer may have invaded the outermost layers of the colon wall, but lymph nodes and distant organs are unaffected.

Stage - 3:

• Further categorised into IIIA, IIIB, and IIIC, indicating the extent of lymph node involvement.
• Cancer has spread to nearby lymph nodes but not to distant organs.

Stage - 4:

• The most advanced stage is where cancer has spread (metastasised) to distant organs or lymph nodes away from the colon, such as the liver, lungs, or other parts of the body.
• Typically, stage IV has sub-stages (IVA, IVB, IVC) based on the location and extent of metastasis.

Colon Cancer Types

Colon cancer is a heterogeneous disease encompassing various types, each with unique characteristics and behaviours. Understanding these types is crucial for accurate diagnosis and tailored treatment plans. Here's a comprehensive overview:

Common types of colon cancer

Adenocarcinoma:

• The most prevalent type, which accounts for the majority of colon cancer cases.
• Arises from the cells that line the inner surface of the colon or rectum.
• Typically starts as a benign growth (polyp) that can turn cancerous over time.

Carcinoid Tumors:

• A less common type originates in the hormone-producing cells of the colon.
• Usually, they grow slowly and might not exhibit symptoms until they reach an advanced stage.

Gastrointestinal Stromal Tumors (GISTs):

• Rare in the colon but can develop in its connective tissues (submucosa or muscular layers).
• Arise from specialised cells called interstitial cells of Cajal.

Lymphomas:

• Uncommon in the colon, these cancers originate in the immune system's lymph cells.
• Usually found in the colon's lymph nodes and can affect the colon's normal functioning.

Sarcomas:

• Rare cancers originate in the blood vessels, muscle cells, or other connective tissues of the colon.
• These include leiomyosarcoma, angiosarcoma, and gastrointestinal stromal tumours (GISTs).

Serrated Polyps and Traditional Serrated Adenomas (TSAs):

• Initially considered benign, some serrated polyps can progress to colorectal cancer, particularly TSAs.

Hereditary Colorectal Cancer Syndromes:

• Conditions caused by specific gene mutations, such as familial adenomatous polyposis (FAP) and Lynch syndrome (hereditary nonpolyposis colorectal cancer or HNPCC), significantly increase the risk of colon cancer.

Understanding these diverse types of colon cancer enables healthcare professionals to tailor treatment plans, prognosis, and monitoring strategies for patients.

Colon Cancer Diagnosis 

Overview of diagnostic procedures for colon cancer 

Diagnosing colon cancer involves a series of tests and examinations to confirm the presence, stage, and extent of the disease. Early diagnosis is critical for successful treatment and improved outcomes. Here is an overview of the diagnostic procedures for colon cancer:

• Colonoscopy:
  • A crucial diagnostic tool and screening method where a flexible, lighted tube (colonoscope) is inserted into the rectum and guided through the entire colon.
  • Enables the visualisation of the colon's lining to detect abnormalities, such as polyps or tumours, which can be biopsied during the procedure.
• Flexible Sigmoidoscopy:
  • Similar to a colonoscopy but examines only the lower part of the colon (sigmoid colon) using a shorter, flexible scope.
  • Provides a detailed view of the rectum and sigmoid colon to identify any suspicious growths.
• Virtual Colonoscopy (CT Colonography):
  • A non-invasive imaging technique using CT scans to generate detailed 3D images of the colon.
  • Effective in detecting polyps and tumours, offering a less invasive option for those who cannot undergo traditional colonoscopy.
• Double-Contrast Barium Enema:
  • Involves a series of X-rays of the colon and rectum after administering a barium solution to coat the colon's lining, providing a clear view of any abnormalities.
• Fecal Occult Blood Test (FOBT):
  • Screens for hidden blood in the stool, which could be a sign of colon cancer or polyps.
  • Convenient and cost-effective, encouraging routine screenings for early detection.
• Carcinoembryonic Antigen (CEA) Blood Test:
  • Measures the levels of CEA, a protein often elevated in individuals with colon cancer.
  • Can be utilised for monitoring treatment response and detecting potential recurrence.
• Biopsy and Histopathological Analysis:
  • Essential for confirming a diagnosis by analysing a tissue sample obtained during colonoscopy or surgery.
  • Helps determine the type, stage, and grade of the cancer for appropriate treatment planning.

Importance of Early Detection and Timely Screenings:

Early detection of colon cancer significantly improves the chances of successful treatment and long-term survival. Timely screenings are paramount for the following reasons:
