New Colon Cancer Screening Tests: A Breakdown of the American Cancer Society's Recommendations
The American Cancer Society has updated its recommendations for colon cancer screening, adding three new tests to encourage more people to get tested regularly. It is crucial for individuals aged 45 to 75 to undergo regular screenings, as recent data shows that less than half of adults aged 45 to 49 have completed their routine colon cancer screenings. Colonoscopies are still considered the best option for screening, but some people may avoid them due to the preparation, sedation, and scheduling challenges. The American Cancer Society now endorses three new tests: a blood test and two more sensitive at-home stool tests, which are more accurate in detecting cancer and pre-cancerous polyps compared to older stool tests. These new tests offer higher sensitivity and only need to be performed every three years, making them a convenient option for screening.
The two new stool tests recommended by the American Cancer Society, Cologuard Plus and ColoSense, are more accurate and sensitive in detecting cancer and pre-cancerous polyps compared to older stool tests. They go beyond checking for blood in stool and look for specific signs of cancer being shed into the bloodstream. These tests have been shown to detect cancer more than 90% of the time, making them a reliable screening option. Additionally, the ACS is now recommending a blood test called Shield from Guardant Health, which can detect about 83% of colorectal cancers found during a colonoscopy. While the blood test may not be as effective in detecting precancerous polyps, it is a viable option for individuals who are unable or unwilling to undergo a visual exam like a colonoscopy or stool test.
The new colon cancer screening tests recommended by the American Cancer Society are typically covered by most major insurance plans, although coverage may vary. While colonoscopies remain the best way to prevent and investigate cancer, the new tests offer alternative screening options for individuals who may be averse to traditional methods. It is important to note that any positive stool or blood test result will require a follow-up colonoscopy for further evaluation. Dr. Andrea Cercek from Memorial Sloan Kettering Cancer Center emphasizes the importance of regular colonoscopies in detecting and preventing cancer, as they can identify polyps before they develop into cancer. While the new tests are effective in detecting cancer, they may not provide the same preventive benefits as a colonoscopy.
In conclusion, the American Cancer Society's updated recommendations for colon cancer screening aim to increase screening rates and improve early detection of colorectal cancer. The addition of new, more sensitive tests provides individuals with alternative screening options that are convenient and effective. While colonoscopies remain the gold standard for cancer prevention, the new tests offer viable alternatives for individuals who may be hesitant to undergo traditional screening methods. Regular screening is essential in reducing the risk of colorectal cancer and improving outcomes for individuals at risk.
