What is a Colonoscopy?
A colonoscopy is a medical procedure that allows a healthcare professional to examine the lining of the large intestine (colon) using a flexible tube with a camera attached.It is typically performed to screen for colorectal cancer, detect and remove precancerous polyps, investigate unexplained abdominal symptoms, or monitor existing conditions like inflammatory bowel disease.
During the procedure, the patient is usually sedated to ensure comfort, and the colonoscope is gently inserted through the rectum into the colon, providing a comprehensive visual assessment of the intestinal lining. A colonoscopy is considered a gold standard for detecting and preventing colorectal cancer, as it allows for early detection, treatment, and the removal of potentially harmful polyps before they develop into cancer.
Why is a Colonoscopy Important?
Colorectal cancer is the third most common cancer worldwide, and early detection is crucial for successful treatment and improved patient outcomes.A colonoscopy can detect precancerous polyps, allowing for their removal before they turn cancerous, reducing the risk of developing colorectal cancer.
It is an effective screening tool, recommended for individuals over the age of 50 or those at higher risk due to family history or certain medical conditions.Regular colonoscopies can help identify and diagnose other gastrointestinal conditions, such as inflammatory bowel disease, diverticulosis, or gastrointestinal bleeding, allowing for appropriate management and treatment.
