Our Specialised Services
We offer diagnostic and screening services that support early detection and timely management of gastrointestinal and colorectal conditions. Our services include:
Colonoscopy Colonoscopy allows direct visualisation of the colon and rectum, helping doctors detect polyps, inflammation and early signs of colorectal cancer before symptoms worsen.
Endoscopy Endoscopy examines the upper digestive tract to identify the cause of symptoms such as pain, reflux or bleeding, enabling accurate diagnosis and appropriate treatment.
Colorectal Cancer Screening Screening helps identify and remove precancerous growths early and detect colorectal cancer at a stage when treatment options are more effective, and outcomes are improved.
How Dangerous and Likely is Colorectal Cancer?
Despite how common it is, colorectal cancer is also one of the most preventable cancers. In many cases, it begins as small growths known as polyps in the colon. These polyps can be detected during a colonoscopy and are often removed during the same procedure.
What Is a Colonoscopy?
A colonoscopy is a procedure that allows doctors to examine the inside of the colon and rectum in real time. During the procedure, a colonoscope, which is a thin flexible tube with a light and camera at its tip, is gently inserted through the rectum and guided through the colon. The camera transmits images to a monitor so the doctor can examine the intestinal lining for abnormalities such as polyps, ulcers, inflammation or cancer.
If polyps are detected, they can usually be removed immediately using specialised instruments passed through the colonoscope. In some situations, the doctor may also take a small tissue sample known as a biopsy for laboratory analysis.
These steps help confirm the diagnosis and guide the next stage of treatment if required.
