Colorectal cancer stands as a prevalent health concern for both men and women, particularly for those aged 50 and above, as indicated by data from the Singapore Cancer Registry. In the landscape of preventive healthcare, the significance of colonoscopy cannot be overstated, serving as a pivotal means for early detection and proactive management of colorectal issues.
A Comprehensive Look at Colonoscopy
Colonoscopy, a medical procedure meticulously designed to scrutinize the colon and rectum for anomalies or signs of diseases, employs a specialized instrument called a colonoscopy. This flexible tube, equipped with a camera at its end, is introduced through the rectum, navigating through the entire colon and the terminal part of the small intestine (ileum). The camera allows healthcare professionals to visually inspect the colon lining, facilitating the identification and removal of polyps, tumors, ulcers, or signs of inflammation.
Identifying Candidates for Colonoscopy
The recommendation for colonoscopies extends to individuals with an elevated risk of colorectal cancer or gastrointestinal diseases, including:
Individuals aged 50 and above Regular colonoscopies are advised, given the escalating risk of colorectal cancer with advancing age.
Those with a family history of colorectal cancer: First-degree relatives with a history of colorectal cancer or polyps should contemplate earlier and more frequent screenings.
Individuals with a personal history of colorectal issues: A regimen of regular surveillance colonoscopies is imperative for those with a past incidence of colorectal cancer or polyps.
Individuals with lifestyle and diet risk factors: Individuals grappling with overweight concerns, smokers, excessive alcohol consumers, and those with a high intake of processed and red meats should undergo colonoscopies to detect potential colorectal issues.
Individuals exhibiting symptoms: Symptoms such as rectal bleeding, changes in bowel habits, abdominal pain, and sudden or unexplained weight loss necessitate consideration for a colonoscopy.
When to have Colonoscopy Screenings
Colorectal screenings, inclusive of colonoscopies, are generally recommended commencing at the age of 50. The screening frequency is contingent upon the risk profile:
For those with low or average risk: A decennial cycle of colonoscopies, starting at age 50, is generally advised.
High-risk individuals: Screening every five years, from age 50 onwards, may be necessary.
Individuals with a family history: Screening approximately a decade before the age at which their relative developed the disease is recommended.
Personalized consultation with a healthcare professional is essential to establish a suitable colonoscopy screening schedule based on individual circumstances. Visit the TVGSC colonoscopy clinic in Singapore for your consultation.
