colorectal cancer incidence

Colorectal cancer is a type of cancer that starts in the colon or rectum, parts of the large intestine. Its incidence refers to how often new cases are diagnosed within a specific population and time. Factors influencing incidence include age, lifestyle, genetics, and screening practices. Typically, incidence increases with age and may vary across different demographics. Early detection through screening can significantly reduce the risk of advanced disease and improve survival. Understanding incidence rates helps public health officials identify at-risk groups and develop strategies for prevention, early diagnosis, and effective treatment.
