COLOTECT, DNA Screening Test for Colorectal Cancer
Colorectal cancer diagnosis at late-stage could result in: patient has to undergo a more complicated treatment course, lower chance of recovery, decreasing the quality of life and higher financial burden incurred from long-term treatment and regular follow-up. Thus, it is crucial for the early diagnosis of colorectal cancer.
There are many options for colorectal cancer screening, and some are designed to detect common colorectal cancer symptoms such as occult blood. However, these tests can miss to detect colorectal cancer if the patient does not present with symptoms during early stage of the disease and limit early cancer diagnosis and treatment.
COLOTECT is an easy-to-do test as the procedure is painless, performable at home or clinic and does not require any bowel preparation or sedation which can be a barrier to colonoscopy. Non-invasive faecal DNA testing can also be used as a screening tool for individuals who are at average risk of developing colorectal cancer. Individuals aged 50-74 who have no symptoms or individual with family history of colorectal cancer are recommended to go for COLOTECT screening, and the test can be repeated for every 3 years. Not only frequent colorectal cancer screening helps saving life, but also assure better life quality and more cost-effective in terms of colorectal cancer management7.
