Colon cancer is a type of cancer that develops in the large intestine (colon), an important part of the
digestive system. It usually starts as small non-cancerous polyps that gradually become cancerous
over time. Early detection is crucial, as colon cancer is highly treatable in its early stages. Common
symptoms include changes in bowel habits, persistent constipation or diarrhea, blood in stool,
abdominal pain, fatigue, and unexplained weight loss. In many patients, early-stage colon cancer
may not show clear symptoms, which makes regular screening very important. Diagnosis includes
colonoscopy, imaging tests, and biopsy. Treatment depends on the stage and may involve surgery,
chemotherapy, radiation therapy, or targeted therapy. With timely diagnosis and advanced
treatment, outcomes have improved significantly.
