Colorectal cancer is one of the most preventable cancers, yet it remains a leading cause of cancer-related mortality. Colonoscopy is the single most effective tool for its prevention and early detection.
What is colonoscopy?
Colonoscopy is a procedure where a flexible camera is used to visualise the entire colon. It allows the physician to detect polyps (pre-cancerous growths), remove them during the same procedure, and diagnose conditions like IBD, diverticulosis, and colorectal cancer at an early, treatable stage.
Who should get screened?
- Everyone aged 45 and above, even without symptoms
- Individuals with a family history of colorectal cancer — screening should begin 10 years before the age of diagnosis in a first-degree relative
- Patients with IBD (Crohn's disease or ulcerative colitis)
- Anyone with rectal bleeding, change in bowel habits, or unexplained anaemia
Is it painful?
The procedure is performed under sedation. Most patients feel no discomfort during the procedure and experience only mild bloating afterward, which resolves within hours.
How often?
For average-risk individuals with a normal result: every 10 years. Higher-risk patients may need more frequent surveillance, as determined by Dr. Parida.
Don't delay screening. A 30-minute procedure can prevent a cancer that takes years to develop.
