A blood test detects colon cancer 83% of the time, finds a study by researchers published in the New England Journal of Medicine.

This is ablood test intended to detect colon cancer in people who are at average risk and have no symptoms of that cancer.

The above conclusion was drawn from the ECLIPSE study, a multi-country clinical trial involving nearly 8,000 people aged 45-84. The researchers compared the blood test, which detects signals of colon cancer in the blood from the DNA shed from the tumors, with a colonoscopy.

More details from the 7,861 people included in the study strong>, 83.1% of colonoscopy-confirmed colon cancer participants had a positive blood test and 16.9% had a negative test.

The test was more sensitive for colon cancers , including early-stage cancers, but less sensitive for advanced precancerous lesions, which can turn into cancer over time.

According to the American Cancer Society, /strong>Colorectal cancer is the second leading cause of cancer death in adults in the US and is expected to cause 53,010 deaths in 2024.

While death rates among older adults have declined, rates among people under of 55 years have increased by about 1% per year since the mid-2000s. Current guidelines recommend that people at average risk for colon cancer begin regular screening at age 45. However, it is estimated that only 50% to 60% of people who need to be screened do these tests.

“Having a blood-based test that people can do against during routine doctor visits, could be an opportunity to help more people get screened,” says William Grady, a gastroenterologist at the Fred Hutchinson Cancer Center and a professor in the Division of Gastroenterology at the University of Washington School of Medicine.< /p>
