At what age should people start colorectal cancer screening now, and are stool tests like Cologuard a good alternative t

Current health guidelines recommend that people at average risk for colorectal cancer begin regular screening at age 45 [1, 3].

Regarding your question about stool tests like Cologuard, they are considered a valid screening option for many people, but whether they are the "right" choice for you depends on your specific health profile and preferences.

• How they work: Stool-based tests look for hidden blood or altered DNA in the stool that may be signs of cancer.
• Comparison to colonoscopy: A colonoscopy is generally considered the "gold standard" because it allows a doctor to both look for and remove precancerous polyps during the same procedure. Stool tests are less invasive and do not require the bowel preparation needed for a colonoscopy, but if a stool test comes back positive, a follow-up colonoscopy is necessary to investigate the results [1].

Because screening needs can vary based on your personal and family medical history, the best approach is to talk with your healthcare provider. They can help you weigh the benefits and limitations of the different testing options to decide which is best for you [1].
