Colon cancer remains one of Singapore’s most significant health concerns. Often developing without noticeable symptoms, it can progress silently until it reaches an advanced stage. While it is among the most commonly detected cancers, high detection rates also reflect increased awareness and participation in screening programmes.
Regular screening, particularly through colonoscopy, plays a vital role in reducing the impact of colon cancer. This procedure allows doctors to identify and remove pre-cancerous growths, known as polyps, before they have the chance to turn malignant, greatly improving long-term outcomes.
Why Colonoscopies Are Essential
A colonoscopy allows doctors to visualise the inner lining of the colon and identify abnormalities such as polyps, inflammation and early signs of cancer.
This procedure serves both diagnostic and therapeutic purposes. Beyond simply examining the colon, colonoscopy enables doctors to take tissue samples for biopsy. If polyps are discovered during the examination, they can often be removed immediately during the same procedure.
Colonoscopy screening in Singapore is recommended for individuals between the ages of 45 and 50, as part of their routine preventive care. However, those with a family history of colorectal cancer and other risk factors or symptoms may need to begin screening earlier.
Benefits of a Colonoscopy
Colonoscopies offer several advantages that contribute to better health outcomes. These include:
Early Detection of Colon Cancer:
A colonoscopy can detect abnormal growths or precancerous polyps at their earliest stage, when treatment is most effective. Early intervention not only improves survival rates but also reduces the complexity of treatment.Prevention of Other Illnesses:
Beyond cancer detection, colonoscopies can also reveal signs of inflammation or infection in the colon. If left untreated, these issues may lead to more serious conditions such as inflammatory bowel disease (IBD) or diverticulosis.Cost-Effective:
Early detection and treatment through regular colonoscopy screening can result in substantial cost savings over time. The cost of screening is significantly lower than the expense associated with treating advanced colon cancer, which often requires extensive surgery, chemotherapy and ongoing medical care.Improved Symptom Management:
Colonoscopies can help diagnose the underlying causes of persistent gastrointestinal symptoms, such as unexplained abdominal pain, chronic diarrhoea, rectal bleeding or changes in bowel habits. This allows doctors to address issues promptly.Enhanced Quality of Life:
By preventing or treating colon-related conditions early, colonoscopies promote better overall health and well-being. In this way, patients can avoid the complications, pain and lifestyle limitations that often accompany advanced colorectal diseases.
Risks of a Colonoscopy
Colonoscopies are generally safe. However, they carry a few potential risks, including:
Minor Bleeding:
Small amounts of bleeding may occur, particularly after polyp removal. This usually resolves on its own and is closely monitored by the medical team.Infection:
Infection is uncommon because the procedure is performed under sterile conditions. When it does occur, it is usually mild and easily treated with antibiotics.Perforation:
In rare cases, the colonoscope may cause a small tear or perforation in the colon wall, which can require surgical repair.Temporary Abdominal Pain:
Some patients may experience mild bloating or abdominal discomfort after the procedure, often due to the air introduced into the colon during examination. These symptoms typically resolve within a few hours.
Early Detection Is Key
When detected early, colon cancer is both preventable and highly treatable. Colonoscopy plays a crucial role in making that possible. If you have concerns about your digestive health, speak with your doctor to assess your risks and determine the right time to schedule a colonoscopy.
