Colorectal Cancer Screening Updates
Screening for colorectal cancer now begins at age 45, rather than the previously established age of 50. This change is critical as early detection through methods like stool-based tests and colonoscopy significantly reduces mortality risks associated with colorectal cancer. This updated guideline reflects an effort to catch potential issues before they develop into cancer, emphasizing the importance of regular screenings. Additionally, understanding the risk factors for colon cancer, including sporadic and familial cases, is vital for targeted screening strategies.
