Raising awareness about colon cancer is crucial for encouraging regular screenings and timely intervention. Early detection can make a significant difference in survival rates, as well as improve the quality of life for patients. This article delves into essential facts about colon cancer, including its causes, symptoms, treatments, and why Korea is a global leader in advanced medical care for this condition.
What is Colon Cancer?
Definition and Overview
Colon cancer occurs when abnormal cells grow uncontrollably in the colon or rectum, which are parts of the large intestine. These cells may form polyps, which can sometimes become cancerous over time. Colon cancer typically develops slowly, starting as benign polyps that gradually evolve into malignant tumors.
Doctors classify colon cancer into various stages based on how far the disease has spread. Early-stage colon cancer is often localized, while advanced stages may involve metastasis to other organs. This classification plays a critical role in determining the best course of treatment and the patient’s prognosis.
How Colon Cancer Affects the Body
The large intestine plays a vital role in the digestive system by absorbing water and nutrients while forming and excreting waste. Colon cancer disrupts these functions, causing symptoms like abdominal discomfort, changes in bowel habits, and in severe cases, intestinal blockages.
