大腸癌

Colorectal cancer is a disease in which cancer develops in the colon or rectum due to uncontrolled growth of cells that can spread to other parts of the body, and it matters because it is commonly caused by preventable lifestyle factors such as diet, obesity, smoking, and lack of physical activity, though genetic factors also play a role. Early signs like blood in the stool, changes in bowel movements, weight loss, abdominal pain, and fatigue can help with detection and treatment.
