It mostly develops from benign growths called polyps; it is a highly preventable cancer with regular colonoscopy.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">What are the symptoms of colon cancer?<\/div><div class=\"hy-faq-a\">It often shows no symptoms in the early stages. Advanced stages may present with blood in the stool, changes in bowel habits, abdominal pain, unexplained weight loss, and fatigue.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">How is colon cancer diagnosed?<\/div><div class=\"hy-faq-a\">Colonoscopy is the gold standard diagnostic method, confirmed via biopsy. CT, PET-CT, and MRI are used for staging. Genetic tests are applied for those with hereditary risks.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">How long does laparoscopic colon surgery take?<\/div><div class=\"hy-faq-a\">Laparoscopic colon surgery takes an average of 2-4 hours. The hospital stay is generally 3-5 days. Prof. Dr. Hakan Yanar performs minimally invasive surgery using laparoscopic and robotic methods.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">Is HIPEC treatment related to colon cancer?<\/div><div class=\"hy-faq-a\">Yes. In advanced cases where colon cancer has spread to the peritoneal membrane, HIPEC can be applied alongside cytoreductive surgery. Prof. Dr. Hakan Yanar is one of the few specialized surgeons in Istanbul with HIPEC certification.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">At what age should I get a colonoscopy?<\/div><div class=\"hy-faq-a\">Individuals with average risk are recommended to begin screening at age 45-50. Those with a first-degree relative history of colon cancer should be screened 10 years prior to the age of onset in their relative.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">Is colon cancer curable in the early stages?<\/div><div class=\"hy-faq-a\">The five-year survival rate for Stage I colon cancer is over 90%. Therefore, regular screening and early diagnosis save lives.<\/div><\/div><div class=\"hy-faq-item\"><div class=\"hy-faq-q\">Is an ostomy permanent after surgery?<\/div><div class=\"hy-faq-a\">Most colon cancer surgeries do not require an ostomy. In rectal cancer cases, a temporary ostomy may be applied, which can be closed later. A permanent ostomy is rarely required.<\/div><\/div><\/div>\r\n\r\n<div class=\"hy-cta\">\r\n  <h3>Book an Appointment for Colorectal Cancer Evaluation<\/h3>\r\n  <p>Contact Prof. Dr. Hakan Yanar today for early diagnosis and treatment.<\/p>\r\n  <div class=\"hy-cta-btns\">\r\n    <a href=\"tel:+905301715814\" class=\"hy-cta-btn primary\">\ud83d\udcde Call Now<\/a>\r\n    <a href=\"https:\/\/wa.me\/905301715814\" class=\"hy-cta-btn wa\" target=\"_blank\">\ud83d\udcac Message via WhatsApp<\/a>\r\n    <a href=\"https:\/\/www.hakanyanar.com\/en\/contact\/\" class=\"hy-cta-btn primary\">\ud83d\udcc5 Online Appointment<\/a>\r\n  <\/div>\r\n<\/div>\r\n<div class=\"hy-related\"><h3>Related Conditions & Treatments<\/h3><div class=\"hy-related-grid hy-cf\"><div class=\"hy-related-card\"><div class=\"hy-related-icon\">\ud83e\uddec<\/div><div class=\"hy-related-name\">HIPEC Treatment<\/div><div class=\"hy-related-desc\">Advanced treatment in peritoneal metastasis<\/div><a href=\"\/en\/services\/hipec\/\" class=\"hy-related-link\">Learn More \u2192<\/a><\/div><div class=\"hy-related-card\"><div class=\"hy-related-icon\">\u2695\ufe0f<\/div><div class=\"hy-related-name\">Gastric Cancer<\/div><div class=\"hy-related-desc\">Laparoscopic gastrectomy<\/div><a href=\"\/en\/services\/gastric-cancer\/\" class=\"hy-related-link\">Learn More \u2192<\/a><\/div><div class=\"hy-related-card\"><div class=\"hy-related-icon\">\ud83e\udd16<\/div><div class=\"hy-related-name\">Robotic Surgery<\/div><div class=\"hy-related-desc\">Minimally invasive technology<\/div><a href=\"\/en\/services\/laparoscopic-robotic-surgery\/\" class=\"hy-related-link\">Learn More \u2192<\/a><\/div><\/div><\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/body>\r\n<\/html>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>General Surgery \u00b7 Istanbul Colorectal Cancer Prof. Dr. Hakan Yanar \u2014 General Surgery Specialist Colorectal cancer offers high cure rates with early detection.
