A Colonoscopy is a medical procedure that allows a doctor to examine the inner lining of the large intestine (colon and rectum). This is achieved by inserting a long, flexible tube equipped with a light and a camera (a colonoscope) through the rectum. The camera transmits images to a screen, enabling the doctor to inspect the intestinal lining for abnormalities such as polyps or signs of cancer.
Common uses of colonoscopy include:
Colonoscopy plays a crucial role in preventive healthcare, particularly in reducing the incidence and mortality of colorectal cancer. Early detection and removal of precancerous polyps can significantly decrease the risk of developing colorectal cancer. This procedure is a pivotal component of recommended screening protocols, particularly for adults over the age of 50 or those with a family history of colorectal issues.
Additionally, colonoscopies are vital diagnostic tools that help healthcare providers identify the cause of gastrointestinal symptoms, allowing for prompt treatment and improved patient outcomes. By facilitating early intervention, colonoscopies contribute to better overall health management and decreased healthcare costs associated with late-stage cancer treatments.
