Can community awareness campaigns in low-resource areas improve early diagnosis of colorectal cancer?

Program in Nigeria has led to cancer detection at curable stages.

2025-12-22

(Press-News.org) In low-resource regions such as Nigeria, most people with colorectal cancer are diagnosed too late for curative treatment options. A community awareness campaign in the country helped clinicians detect both early-stage and advanced colorectal cancer in patients who had not been aware that they should be screened. That’s according to a study published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

For the study, investigators conducted a 6-month community awareness campaign, with information, education, and communication materials—including bilingual flyers, posters, banners, radio jingles, and social media—about colorectal cancer symptoms and risk factors. These materials were distributed during community events, clinic visits, and through religious institutions.

Among 497 participants, 322 completed surveys both before and after the campaign. Only 16.8% had awareness of colorectal cancer before the campaign, but 96.9% had awareness after the campaign. Good knowledge of colorectal cancer risk factors and symptoms also increased significantly.

Individuals with indicators of colorectal cancer based on baseline survey results were referred by health care workers and patient navigators to an Early Diagnosis Clinic. Among 329 individuals who went to the Early Diagnosis Clinic, 168 (51.1%) were identified as having risk factors for colorectal cancer (such as unexplained changes in bowel habits or anal ulcerations, or a family history of colorectal cancer), and 116 (73.0%) completed a colonoscopy. Colorectal cancer was diagnosed in four patients (3.4%), with two having stage 0, one having stage II, and one having stage III disease. Precancerous polyps (advanced adenomas) were identified in 11% of the patients who underwent colonoscopy.

“This program is the first of its kind to demonstrate a program in sub-Saharan Africa that includes both community education and symptoms that trigger navigation to a colorectal cancer early diagnosis clinic to prevent cancer in patients with advanced adenomas and identify colorectal cancer in curable stages,” said senior author T. Peter Kingham, MD, of the African Research Group for Oncology, in Nigeria, and the Memorial Sloan Kettering Cancer Center, in New York City.

Stardust study resets how life’s atoms spread through space

2025-12-22

Starlight and stardust are not enough to drive the powerful winds of giant stars, transporting the building blocks of life through our galaxy. That’s the conclusion of a new study from Chalmers University of Technology, Sweden, of red giant star R Doradus. The result overturns a long-held idea about how the atoms needed for life are spread. “We thought we had a good idea of how the process worked. It turns out we were wrong. For us as scientists, that’s the most exciting result”, says Theo Khouri, astronomer at Chalmers and joint leader of the study. To understand the origins ...

Practical education: Clinical scenario-based program development

2025-12-22

To reduce mortality rates, fall and tumble rates, and delirium incidence among hospitalized patients, it is crucial for nurses to learn Evidence-Based Practice (EBP). To achieve this, developing effective EBP education programs is essential. However, traditional EBP education programs have faced challenges, such as not covering all aspects of the EBP process and lacking rigorous evaluation methods for these programs. Dr. Hideaki Furuki and colleagues at Osaka Metropolitan University’s Graduate School of Nursing ...

The impact of family dynamics on eating behaviour – how going home for Christmas can change how you eat

2025-12-22

As the holiday season approaches, many families will gather around the dinner table, sharing meals and memories. But what if the way we eat during these gatherings is shaped by more than just tradition? Psychology research shows that our families and upbringing have a massive impact on how we eat and our relationship towards food. In fact, these influences are so profound that they can mean some people dread visiting family for the festivities. In an in-depth study of the psychology of eating, Professor in Health Psychology Jane Ogden delves into the profound impact of family dynamics on eating behaviour, ...

Tracing the quick synthesis of an industrially important catalyst

2025-12-20

Tokyo, Japan – Researchers from Tokyo Metropolitan University have successfully traced the mechanism behind how an industrially important “superbase” catalyst is synthesized in a faster, microwave-assisted reaction. They took measurements using X-rays while the reaction occurred, uncovering how small precursor molecules were formed first before they clustered to create the final product. Their insights promise finer control over a promising technology for speeding up chemical synthesis in industry. Polyoxometalates are industrially ...

From straw to soil harmony: International team reveals how biochar supercharges carbon-smart farming

2025-12-19

What if the secret to climate-friendly farming wasn’t in futuristic tech—but in how we manage what’s already on the field? Imagine turning leftover maize stalks not into smoke from open burning, but into a powerful soil ally—especially when paired with its charred cousin, biochar. That’s exactly what a new international study has uncovered: a simple yet transformative strategy that cuts carbon emissions, boosts soil health, and even encourages microbes to work together like never before. Published on October 27, 2025, in the open-access journal Carbon Research (Volume 4, Article 68), this collaborative research bridges Moscow and Guangzhou to deliver one of the ...

Myeloma: How AI is redrawing the map of cancer care

MIAMI, FLORIDA (Dec 19, 2025) – C. Ola Landgren, M.D., Ph.D., received HealthTree Foundation’s prestigious 2025 Innovation Award for his work in developing CORAL, a new research tool that leverages AI to predict individual outcomes and guide treatment decisions in patients with multiple myeloma. Using deep learning to read standard bone marrow biopsy slides like pages in a book, CORAL spots patterns in a patient’s cancer to accurately predict genetic subtypes and patient outcomes, bypassing the traditional need for expensive, time-consuming genomic tests. Landgren, director of the Sylvester Myeloma Institute at Sylvester Comprehensive ...
