First Colonoscopy Age

The recommended age to begin regular colonoscopy screenings has recently changed. According to the U.S. Preventive Services Task Force, individuals at average risk for colorectal cancer should start screening at age 45. This is a shift from the previous guideline of starting at age 50, reflecting an increase in colorectal cancer cases among younger adults.

Risk Factors for Earlier Screening

Certain risk factors may necessitate earlier screening or more frequent colonoscopies. Individuals who should consider getting screened before age 45 often include:

• Family History: A strong family history of colorectal cancer or certain types of polyps can increase risk. Screening recommendations may vary based on who in the family had cancer and their age at diagnosis.
• Personal History: If you have a personal history of colorectal cancer, adenomatous polyps, or inflammatory bowel disease (such as Crohn's disease or ulcerative colitis), you may need to start screening earlier and undergo more frequent tests.
• Genetic Syndromes: Conditions like familial adenomatous polyposis (FAP) or Lynch syndrome significantly raise the risk of colorectal cancer, often requiring screening to begin in adolescence or early adulthood.
• Prior Radiation Treatment: Individuals who have received radiation therapy to the abdomen or pelvic area for other cancers may also need to begin screening earlier.
