Colon cancer is a type of cancer that begins in the colon, which is the lower part of the digestive system. It often starts as small growths called polyps that can develop into cancer over time. Symptoms may include changes in bowel habits, blood in the stool, and abdominal discomfort. Early detection through screenings like colonoscopy can significantly improve treatment outcomes. Risk factors for colon cancer include age, family history, and certain lifestyle choices such as a diet high in red meat and low in fiber. Regular exercise and a balanced diet can help reduce the risk. Awareness and education are key to prevention and early detection.
