Colon cancer also referred to as colorectal cancer, is one of the most common cancer types worldwide. Recent research shows rising incidence rates of colon cancer across all age brackets, though the condition primarily gets detected in people between 65 and 74 years old. The pattern of colon cancer occurs most commonly in Western countries. Still, in India, people get rectal cancer more often, and this disease affects men to a higher degree than women.
The starting point of colorectal cancer occurs in the mucosa layer of the colon or rectum and spreads across various tissue levels. The severity of tissue penetration by the cancerous cells determines which stage of cancer a person has. Routine screening detection helps improve treatment success rates.
What are the Symptoms of Colon Cancer?
Colon cancer remains undetectable during its first stages. People with progressive disease typically encounter different health issues that include:
- Persistent Changes in Bowel Habits: Pinkish-red or dark black stools signal internal bleeding. Bowel habits may become consistently loose or constipated, leading to a feeling of incomplete bowel emptying, known as tenesmus.
- Blood in Stool: Bright red blood or dark, tarry stools are indicators of internal bleeding.
- Anaemia: The condition results in reduced red blood cells from internal bleeding, which produces fatigue and dizziness and leads to pale skin appearance.
- Unexplained Weight Loss: Losing weight without dietary or activity changes.
- Loss of Appetite: Reduced hunger due to metabolic changes, digestive obstructions, or systemic inflammatory effects.
- Fatigue: Persistent tiredness despite adequate rest.
- Advanced Stage Symptoms: Abdominal pain, distension, severe constipation (obstipation), and abnormal connections between the colon and other organs (colovaginal or colovesical fistulae).
According to a study, rectal bleeding (37%), abdominal pain (34%), and anaemia (23%) were the most often occurring symptoms triggering diagnostic colonoscopies.
What are the Causes of Colon Cancer?
A combination of several risk elements leads to colon cancer formation, including:
- Genetics: A family history of colorectal cancer or inherited syndromes such as Familial Adenomatous Polyposis (FAP) and Lynch syndrome increases the risk.
- Lifestyle Factors: A combination of unhealthy eating habits, a sedentary life, smoking, and heavy alcohol use together raise the potential for colon cancer development.
- Inflammatory Bowel Diseases (IBD): Conditions such as Crohn’s disease and ulcerative colitis cause chronic inflammation, increasing susceptibility to colon cancer.
- Age: Routine screenings become essential for middle-aged people and those older than 50 years since they experience higher risks of developing colon cancer.
- Environmental Factors: Exposure to toxins alongside environmental pollutants plays a part in developing colorectal cancer.
- Mutations in DNA: When DNA undergoes mutations, the cells start uncontrollable growth, which forms malignant tumours.
Risk Factors for Colon Cancer
- Older Age: Most colorectal cancer diagnoses occur in people fifty and above, although such cancers may emerge in any age period.
- African-American Descent: Evidence shows that African-American people face an increased probability of developing colorectal cancer.
- History of Colorectal Cancer or Polyps: People who have experienced colorectal cancer or polyps before have greater chances of getting a recurrence of the disease.
- Inflammatory Bowel Disease: It represents one set of chronic conditions, which includes ulcerative colitis and Crohn’s disease.
- Diet Low in Vegetables: Eating small amounts of vegetables increases colon cancer risks because such diets lack fibre.
- Lack of Physical Activity: Regular physical exercise reduces the chances of developing cancer, thus lowering the risk.
- Obesity, Smoking, and Alcohol Consumption: Studies reveal that obesity, together with smoking and alcohol consumption, consistently increases the risk for colorectal cancer development.
- Radiation Therapy for Previous Cancer: Any previous cancer treatment with radiation makes the body more vulnerable to developing colorectal cancer.
How is Colon Cancer Diagnosed?
The early discovery of colon cancer leads to better treatment efficiency. Diagnostic methods include:
- Screening Tests: Regular colonoscopy examinations and faecal occult blood tests (FOBT) identify developing abnormalities before symptoms emerge.
- Colonoscopy: A colonoscopy enables a detailed examination of the colon and biopsy procedures to remove any detected polyps.
- Imaging Tests: CT scans, alongside MRI and PET scans, provide medical experts with data on disease extent.
Treatment for Colon Cancer at Chirag Global Hospital
Doctors at Chirag Global Hospital determine colon cancer treatment based on the stage of the disease. They assess the tumour’s size, depth of invasion into the colon, and whether it has spread to other organs. These treatments primarily include:
- Surgery: Tumour removal is the base treatment method for early-stage cancer patients.
- Radiation Therapy: Targeted radiation minimises damage to surrounding healthy tissues while destroying cancer cells.
- Chemotherapy: The medical treatment of chemotherapy functions for both advanced cancers and after surgery to eliminate any leftover cancer cells.
- Hormonal and Biological Therapy: Treatment approaches in hormonal and biological therapy block cancer expansion signals by applying precision medicine techniques.
- Local Ablative Therapy: Non-surgical methods such as radiofrequency ablation to destroy cancer cells.
- Combination Therapy: The treatment approach for some cases involves surgical procedures, chemotherapy, and radiation therapy.
