「S状結腸がんの転移先と予防法｜大腸がんで見逃しやすい危険部位を医師が完全解説」

Sigmoid colon cancer is one of the most common types of colorectal cancer. While early-stage sigmoid colon cancer can be treated endoscopically, at stage 4, metastasis to the liver and other organs becomes difficult, making complete resection challenging. This video provides a comprehensive explanation by a doctor, covering the anatomical characteristics of the sigmoid colon, precautions during endoscopic examinations, staging, metastasis sites, and preventative measures you can take now. ▼ What you will learn in this video ✅ What is sigmoid colon cancer? Differences from colorectal cancer ✅ Risks associated with the "free movement" of the sigmoid colon (volvulus, ischemic colitis, diverticulum) ✅ Cases where endoscopic examination (colonoscopy) becomes difficult and precautions to take ✅ Differences between stages 0-4 and metastasis sites (liver, lymph nodes, peritoneum, lungs) ✅ Why red meat, processed meat, and lack of exercise increase the risk of colorectal cancer ✅ Specific preventative measures through diet, exercise, abstinence from alcohol, and smoking cessation ▼ Table of Contents 00:00 Opening 00:03 What is sigmoid colon cancer? 00:23 Benefits of Early Detection and Treatment 00:53 Cases Treatable with Endoscopy (Colonoscopy) 01:09 Signs and Examinations for Early Detection 01:27 Anatomical Characteristics of the Sigmoid Colon 01:54 Mobility and Risks of the Sigmoid Colon (Jump Rope Analogy) 02:40 Diseases Specific to the Sigmoid Colon (Volvulus, Ischemic Colitis, Diverticulitis) 03:19 Precautions During Colonoscopy 04:35 History of Abdominal Surgery and Adhesion Risk 05:24 Staging Classification of Colorectal Cancer (0-4) 05:29 Stages 0, 1, and 2: Local Cancer and Treatment Methods 06:03 Stage 3: Lymph Node Metastasis and Treatment 06:52 Stage 4: Distant Metastasis Sites (Liver, Peritoneal, Lungs) 08:12 Basic Concepts of Colorectal Cancer Prevention 08:54 Dietary Prevention (Reduce Red Meat and Processed Meat) 09:19 Prevention through exercise (150 minutes of aerobic exercise per week) 09:52 Other lifestyle habits (moderate alcohol consumption, quit smoking) 10:12 Summary ▼ Recommended for: ・Those considering regular colorectal cancer screenings ・Those diagnosed with sigmoid colon cancer or their families ・Those feeling anxious about endoscopic examinations (colonoscopy) ・Those who want to reduce their risk of colorectal cancer through lifestyle changes. Colorectal cancer is a "curable cancer" if detected early. The sigmoid colon, in particular, is one of the areas of the large intestine where cancer frequently occurs, and in stages 0-1, it can often be treated with endoscopy alone. However, once it progresses to stage 4, metastasis to the liver becomes the most common, making complete resection difficult. That's why it's important to understand the risks correctly and work towards prevention and early detection.
