Colorectal cancer (CRC) ranks among the leading causes of cancer-related deaths globally. However, early detection through cancer screening plays a crucial role in significantly improving survival rates. In Malaysia, screening facilities are readily available to detect precancerous polyps or early-stage cancers, when treatment is most effective. At Gleneagles Hospitals, we provide comprehensive colorectal cancer screening services supported by experienced specialists and advanced medical technologies. The lifetime risk of developing colorectal cancer is estimated at approximately 1 in 24 for men and 1 in 26 for women.
Importance of Colorectal Cancer Screening
Screening is an essential preventative measure for colorectal cancer. Its benefits include:
- Early Detection: Increases the likelihood of successful treatment by identifying cancer at an early, more treatable stage.
- Prevention: Enables the detection and removal of polyps before they progress to cancer.
- Higher Survival Rates: When colorectal cancer is found early, the five-year survival rate exceeds 90% (National Cancer Institute, 2022).
- Cost-Effectiveness: Treating early-stage cancer is generally less expensive than managing advanced disease.
Understanding Risk Factors for Colorectal Cancer
While everyone carries some level of risk for CRC, certain individuals are more susceptible. Understanding these risk factors helps determine appropriate screening timelines:
Individuals at Increased Risk:
- Age: Risk increases for individuals aged 45 and above (CDC, 2021).
- Family History: Those with a first-degree relative diagnosed with CRC face higher risk.
- Genetic Syndromes: Conditions such as Lynch syndrome and familial adenomatous polyposis (FAP) raise the likelihood of developing CRC.
- Lifestyle Choices: Sedentary habits, obesity, tobacco use, and excessive alcohol consumption elevate risk.
- Diet: High consumption of red or processed meats and low intake of dietary fibre contribute to colorectal cancer risk.
- Medical Conditions: Chronic inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis are associated with higher risk.
Recognising Symptoms of Colorectal Cancer
Early stages of colorectal cancer often present no symptoms. However, recognising potential warning signs is vital for early intervention:
Persistent changes in bowel habits, including prolonged diarrhoea, constipation, or narrowing of stools.
Rectal bleeding, which may present as bright red blood or dark-coloured stools.
Abdominal discomfort, including cramping, bloating, or ongoing pain.
Unexplained weight loss.
Persistent fatigue, particularly when linked to anaemia from internal bleeding.
If any of these symptoms last longer than two weeks, a medical evaluation is strongly advised. Timely diagnosis can significantly enhance treatment outcomes.
