Colonoscopy News and Research

RSS

Colonoscopy is examination of the inside of the colon using a colonoscope, inserted into the rectum. A colonoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease.

Automated text messages improve bowel cancer screening in London

As low-cost and straightforward an intervention as automated text messaging could make a significant contribution to tackling London's below-average bowel cancer screening rates, according to a major study led by the University of Surrey.

Rising colorectal cancer rates prompt earlier routine screening recommendations

Forty-five is the new 60 – at least when it comes to colonoscopies. That may not be the party you look forward to, but it could save your life. According to the Cancer Research Institute, 1 in 5 colorectal cancers are diagnosed in patients under age 55, making what was once thought of as an older person's disease one of the fastest-growing cancers in young people.

Late diagnosis and systemic gaps drive high cancer death rates in the Balkans

In the Balkans, cancer survival rates lag due to late diagnoses and weak screening programs, highlighting the need for improved early detection strategies.

Garvan research reveals hidden inflammation behind high colon cancer risk

New research from the Garvan Institute of Medical Research has revealed for the first time that two closely related bowel diseases, currently treated in the same way, are fundamentally different.

Simple fecal test could help detect colorectal and pancreatic cancers

Gastrointestinal and pancreatobiliary cancers can be difficult to detect early, creating a need for practical, noninvasive approaches for early detection and risk assessment.

New AI tool automates colonoscopy quality assessment at scale

Colonoscopies are one of the most effective ways to prevent colorectal cancer, which is surging among young adults in the U.S. Yet, the quality of each procedure can vary substantially from one physician to another.

New study tracks global colorectal cancer risk across 185 nations

Colorectal cancer has long been recognized as a major global health threat, but its burden is far from evenly distributed. Incidence and mortality rates vary dramatically across countries, and these differences are closely tied to socioeconomic development, dietary transitions, and the adoption of screening programs.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Only 15% of eligible American adults discuss lung cancer screening with their doctors

Lung cancer screenings can save lives by detecting cancer in its early stages, but only 15% of eligible American adults have discussed the screening with their doctors, according to data analysis performed by University of Cincinnati Cancer Center researchers.

Active screening cuts colorectal cancer death risk drastically

People who take part in screening for colorectal cancer may have as much as 43 per cent lower risk of dying from the disease, according to new estimates published in JAMA Network Open by researchers at Karolinska Institutet and Umeå University in Sweden.

New study highlights noninvasive biomarkers for colorectal cancer detection

Emerging discoveries in liquid biomarker research promise to transform early detection, diagnosis, and treatment monitoring of colorectal cancer (CRC), according to a new study, offering less invasive alternatives to traditional methods that often require surgical interventions or tissue biopsies.

AGA experts highlight benefits and limits of colorectal cancer screening tests

As new colorectal cancer screening guidance draws attention to the growing number of testing options, the American Gastroenterological Association urges patients and primary care providers to understand how those options compare.

New manufacturing platform produces targeted mixtures of beneficial gut bacteria

Researchers at the Icahn School of Medicine at Mount Sinai have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

New colorectal cancer screening guidelines emphasize advanced stool tests

With colorectal cancer a growing concern among younger people, the American Cancer Society has endorsed two new types of stool tests to encourage people to get screened while also recommending a limited role for new blood tests many patients find appealing.
