endoscopy (or gastroscopy) involves inserting a thin, flexible tube with a camera through the mouth to examine the stomach:<\/p><p>This allows the doctor to view the stomach lining in real time, identify any suspicious areas such as growths, ulcers or inflammation, and take biopsy samples for laboratory analysis.<\/p><p>Unlike tests that provide only indirect clues, such as <a href=\"https:\/\/richmondgastro.com.sg\/what-do-tumour-markers-really-reveal-about-your-health\/\">digestive tumour marker<\/a> assessments, endoscopy offers direct visualisation and the <b>opportunity for tissue sampling<\/b>. A definitive diagnosis of stomach cancer requires a biopsy, which is obtained during an endoscopy<\/p><h3>Why did my doctor order other tests then?<\/h3><p>Patients often wonder \u2014 if endoscopy is the most accurate way to diagnose stomach cancer, why are blood tests, imaging scans or other investigations still necessary?<\/p><p>It\u2019s a reasonable question.<\/p><p>In short, <b>each test has its own important role<\/b>. These investigations help assess your overall health, pick up potential complications and provide supplementary information that supports your doctor in planning the most appropriate care.<\/p><h3>When should you consider an endoscopy?<\/h3><p>You may be advised to undergo an endoscopy if you experience:<\/p><ul><li>Persistent or unexplained upper abdominal pain<\/li><li><a href=\"https:\/\/richmondgastro.com.sg\/abdominal-pain-and-bloating\/\">Persistent bloating<\/a>, indigestion, or early fullness<\/li><li>Unexplained weight loss or loss of appetite<\/li><li>Vomiting or passing black stools<\/li><li>Family history of stomach cancer<\/li><\/ul><p>If you have risk factors such as H. pylori infection, long-term gastritis, or are over 50 years old, regular endoscopic screening may also be recommended for early detection.<\/p><p>Most importantly, if you simply want peace of mind, you can choose to undergo an endoscopy or gastroscopy at any time \u2013 especially as <a href=\"https:\/\/cancerblog.mayoclinic.org\/2025\/02\/11\/as-stomach-cancer-rates-rise-in-younger-people-knowing-symptoms-and-family-history-is-key\/\">stomach cancer rates are rising among younger individuals<\/a>.<\/p><p>With available subsidies and private insurance coverage, endoscopy has become much more accessible today.<\/p><h3>Summary<\/h3><p>While blood tests and imaging provide useful information, endoscopy remains the most reliable way to assess the stomach when there is concern about cancer.<\/p><p>It allows doctors to view the stomach lining directly and obtain tissue samples, which are essential for confirming a diagnosis.<\/p><p>If you\u2019ve been <b>experiencing ongoing digestive symptoms<\/b> or have risk factors for stomach cancer, consider discussing your concerns with a gastroenterologist to determine whether an endoscopy may be appropriate for you.<\/p><h3>Considering your next steps<\/h3><p>If certain symptoms have been persisting or something simply does not feel right, speaking with a gastroenterologist can help clarify what tests may be appropriate.<\/p><p>You can explore these concerns further with our <a href=\"https:\/\/richmondgastro.com.sg\/\">gastroenterology clinic in Singapore<\/a>, where our doctor will guide you on the most suitable next steps.<\/p><p>\u00a0<\/p>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-60ddd13 elementor-widget elementor-widget-pxl_text_editor\" data-id=\"60ddd13\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"pxl_text_editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"pxl-text-editor default\">\n\t<div class=\"pxl-item--inner  \" data-wow-delay=\"ms\">\n\t\t<blockquote><p><br \/><i>While blood tests and imaging can suggest abnormalities, only an endoscopy can confirm the diagnosis with certainty.<\/i><\/p><p><cite>Tumour marker tests are not 100% accurate.<\/cite><\/p><\/blockquote>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-34ba0c3 elementor-widget elementor-widget-pxl_text_editor\" data-id=\"34ba0c3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"pxl_text_editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"pxl-text-editor default\">\n\t<div class=\"pxl-item--inner  \" data-wow-delay=\"ms\">\n\t\t<p><strong>References:<\/strong><\/p><ol><li>Bredenoord, A.
