Understanding Colorectal Cancer
Colorectal cancer affects the colon or rectum, parts of the digestive system responsible for processing waste. It often begins as benign polyps that can turn cancerous over time. Colorectal Cancer Awareness Month is observed every March to educate people about early detection and prevention strategies.
Common Myths and the Truth Behind Them
Myth 1: Only Older Adults Get Colorectal Cancer
Reality: While it is true that the risk increases with age, younger adults are also being diagnosed with colorectal cancer at an alarming rate. Lifestyle factors, genetics, and diet play a crucial role in its development.
Myth 2: Colorectal Cancer is Always Fatal
Reality: If detected early, colorectal cancer treatment is highly effective. Survival rates are significantly higher when the cancer is diagnosed in its early stages. Regular screenings can catch precancerous polyps before they become a serious threat.
Myth 3: Colonoscopies Are Painful and Unnecessary
Reality: A colonoscopy is a simple, usually painless procedure that can detect abnormalities before they turn into cancer. It is one of the most effective tools for colorectal cancer prevention and should not be avoided due to fear.
Myth 4: No Symptoms Means No Risk
Reality: Colorectal cancer symptoms may not appear in the early stages. Symptoms like changes in bowel habits, blood in the stool, and unexplained weight loss often develop in later stages. This is why regular screenings are essential.
Myth 5: Diet and Lifestyle Have No Effect on Colon Health
Reality: A diet high in red and processed meats, low fibre intake, smoking, excessive alcohol consumption, and a sedentary lifestyle can increase colorectal cancer risk factors. Eating fibre-rich foods, exercising, and avoiding smoking can lower your risk.

Risk Factors: What Really Matters?
Understanding colorectal cancer risk factors is crucial for prevention. Some common risk factors include:
-
Genetics: A family history of colorectal cancer increases your risk.
-
Lifestyle Choices: Poor diet, smoking, and lack of exercise contribute to increased risk.
-
Medical Conditions: Inflammatory bowel diseases like Crohn’s disease and ulcerative colitis can lead to higher chances of developing cancer.
-
Obesity: Being overweight is directly linked to an increased risk of colorectal cancer.
Screening & Early Detection: Separating Fact from Fiction
Early detection can save lives. Screening options include:
-
Colonoscopy: The gold standard in early detection.
-
Stool Tests: Non-invasive tests that detect hidden blood.
-
CT Colonography: A less invasive imaging technique.
The recommended age for screening starts at 45, but earlier screenings are advised for high-risk individuals.
Types of Colorectal Cancer
There are different types of colorectal cancer, including:
-
Adenocarcinoma: The most common type, making up 95% of cases.
-
Carcinoid Tumors: Arising from hormone-producing cells.
-
Gastrointestinal Stromal Tumors (GISTs): Rare tumours that form in the digestive tract.
-
Lymphomas: A type of cancer affecting immune cells in the colon.
Treatment & Survival: Hope vs. Fear
Colorectal Cancer Surgery
For many patients, colorectal cancer surgery is the first line of treatment. The type of surgery depends on the location and stage of the cancer. Some common procedures include:
-
Polypectomy: Removal of small polyps.
-
Colectomy: Partial or total removal of the colon.
-
Laparoscopic Surgery: Minimally invasive techniques for faster recovery.

Colorectal Cancer Medication & Therapies
Treatment options depend on the stage of cancer and may include:
-
Chemotherapy: Used to kill cancer cells or prevent recurrence.
-
Radiation Therapy: Often combined with surgery for rectal cancer.
-
Targeted Therapy: Uses drugs to attack specific cancer cells.
