Endoscopic techniques are central to the diagnosis and management of colorectal cancer, the third most common malignancy worldwide. Colonoscopy remains the gold standard, allowing for direct visualization of the colonic mucosa, detection of early neoplastic lesions, and precise biopsy of suspicious areas. Recent advances such as high-definition colonoscopy, chromoendoscopy, and narrow-band imaging have enhanced the detection of subtle or flat lesions, improving early diagnosis rates. Endoscopic ultrasound further aids in local staging by assessing tumor invasion depth and regional lymph node involvement. These minimally invasive methods have significantly contributed to the reduction of colorectal cancer morbidity and mortality through early detection and intervention. Ongoing innovations in endoscopic imaging and artificial intelligence promise to further refine diagnostic accuracy and patient outcomes in colorectal cancer care.
