"I was surprised by the results, honestly", he said.

Colon cancer signs can include persistent cramps and changes in bowel habits, along with bloody stools. "After reviewing this data, experts on the ACS Guideline Development Committee concluded that a beginning screening age of 45 for adults of average risk will result in more lives saved from colorectal cancer".

If the test is positive, a colonoscopy is recommended, Wender says, but only one in five people test positive for blood in their stool.

The researchers also commissioned a microsimulation modeling study involving a model called MISCAN, which simulates colorectal cancer incidence and mortality and estimates risk factors and the impact of screening and treatment practices.

"A recent analysis found that adults born around 1990 have twice the risk of colon cancer and four times the risk of rectal cancer compared with adults born around 1950", Weinstein said.

Currently, USPSTF, a government-backed independent panel that assesses the evidence for medical procedures, recommends screening from the age of 50. The disease leads to over 50,000 deaths annually, making it the second leading cause of cancer fatalities among American adults. As part of the review process, the USPSTF took into account three computer simulations that considered different starting ages and screening intervals. Clinical trials are the "gold standard" for proving that - and most trials of screening have not included people younger than 50. By 2030, 10.9 percent of all colon cancers and 22.9 percent of all rectal cancers will be diagnosed in patients younger than age 50.

Moscow denies involvement in murder of anti-Kremlin journalist
Russian Foreign Minister Sergey Lavrov responded by denouncing the Ukrainian accusations, calling the killing a "tragedy". Babchenko, a veteran Russian war correspondent, was shot three times in the back as he left his apartment to buy bread.

"Moving the start of screening back to age 45 for the average risk population is a considerable change", says Andrea (Andi) Dwyer, director of the Colorado Colorectal Screening Program at the University of Colorado Cancer Center and program director at the Colorado School of Public Health.

The organization says it's seen an increase in young people getting colon cancer recently.

And, since most people do not start colorectal cancer screening until age 50, changes in screening rates would not account for the increase among younger Americans, he added.

Additionally, more research could shed light on why there has been a rise in colorectal cancer among these younger adults, said Dr. George Chang, chief of colorectal surgery at MD Anderson Cancer Center in Houston, who was not involved in the updated guidelines. Cologuard is not for everyone; not for high risk individuals, including those with a family history of colorectal cancer, a personal history of colorectal cancer or advanced adenoma, IBD and certain hereditary syndromes.

Dr. Nilofer Saba Azad, associate professor of oncology at Johns Hopkins Medicine in Baltimore, agrees with the newly updated guidelines.

She said rates are not only increasing among people in their 40s, but also among those in their 20s and 30s (though the incidence at those ages remains low). With that, we've noted that the incidence is going up in younger people, even younger than 45.
