Endoscopic Screening

Endoscopic procedures like gastroscopy and colonoscopy are life-saving procedures. They not only reveal the causes of any gastrointestinal symptoms that you might have they may also detect life-threatening conditions early so that you have the opportunity to reverse and cure them.

This is especially so if patients are willing to follow a program of routine screening even when asymptomatic. One example of this is the colorectal cancer prevention program. During the colonoscopy, polyps are frequently found. Some of these polyps are premalignant. Endoscopic removal of these polyps has been scientifically proven to prevent or reduce the incidence of colorectal cancer.

Stomach cancers are caused by a bacteria called Helicobacter pylori which can be detected through gastroscopy and eradicated. Early gastric cancer can be removed via endoscopy and cured.

Endoscopy can save lives and screening has resulted in a huge decline in the incidence of gastrointestinal cancers.
