Colorectal cancer is a prevalent concern for both men and women, particularly those aged 50 and above, as highlighted by the Singapore Cancer Registry. In the realm of preventive healthcare, colonoscopy emerges as a crucial tool for early detection and prevention of colorectal issues.
Understanding Colonoscopy
A colonoscopy is a medical procedure designed to scrutinize the colon and rectum for abnormalities or signs of diseases. It involves the use of a colonoscope—a flexible tube with a camera at its end—which is gently guided through the rectum, traversing the entire colon and the last section of the small intestine (ileum). This camera allows doctors to visually inspect the colon lining, identifying issues such as polyps, tumors, ulcers, or signs of inflammation. sdsds
Who Should Consider a Colonoscopy?
Colonoscopies are recommended for individuals with an elevated risk of colorectal cancer or gastrointestinal diseases, including:
Individuals aged 50 and above: Regular colonoscopies are advisable as the risk of colorectal cancer increases with age.
Those with a family history of colorectal cancer: First-degree relatives with a history of colorectal cancer or polyps should consider earlier and more frequent screenings.
Individuals with a personal history of colorectal issues: Regular surveillance colonoscopies are essential for those who have had colorectal cancer or polyps in the past.
Individuals with lifestyle and diet risk factors: Overweight individuals, smokers, excessive alcohol consumers, and those with high consumption of processed and red meats should undergo colonoscopies to detect potential colorectal issues.
Individuals showing symptoms: Rectal bleeding, changes in bowel habits, abdominal pain, sudden or unexplained weight loss are symptoms warranting consideration for a colonoscopy.
When to Schedule a Colonoscopy Screening
Colorectal screenings, including colonoscopies, are recommended from the age of 50. The screening frequency depends on the risk level:
For low or average risk, a colonoscopy every 10 years, starting at age 50, is generally advised.
High-risk individuals may need screenings every five years, beginning at age 50.
Individuals with family history should undergo screening around 10 years before the relative developed the disease.
Individualized consultation with a doctor is crucial to establish an appropriate colonoscopy screening schedule based on individual circumstances. Visit TVGSC colonoscopy clinic in singapore for your consultation.
