(Press-News.org) Every year, more than 200,000 children under the age of 15 are diagnosed with cancer worldwide, and nearly 75,000 die from the disease. Most of these deaths occur in Africa, Asia, and Latin America, even though childhood cancer is more common in Europe and North America. In high-income countries, over 80% of children survive, while the global average is just 37%. Why is the gap so large?
Striking differences
An international study using data from the International Agency for Research on Cancer (IARC), analyzed data from nearly 17,000 children in 23 countries across Africa, Asia, and Latin America. The results show striking differences: in Puerto Rico, almost 80% of children with central nervous system tumors survive three years after diagnosis, compared to only 32% in Algeria. For leukemia, the disparity is even greater – from 30% in Kenya to 90% in Puerto Rico.
Survival is closely linked to a country’s level of development. These variations largely reflect differences in healthcare systems and can be attributed to late diagnosis, limited treatment options, suboptimal quality of care, or treatment abandonment.
In addition, many countries lack reliable cancer registries, making it difficult to determine the true scale of the problem.
“The stark differences in survival – from over 80% in high-income countries to less than 40% in some low- and middle-income countries – underscore the urgent need to act”, comments first-author Dagrun Slettebø Daltveit from the University of Bergen.
Better monitoring is needed
“The World Health Organization (WHO) has set a goal to increase global survival to at least 60% by 2030”, says Dr Isabelle Soerjomataram, Deputy Head of the Cancer Surveillance Branch at IARC,
“To achieve this, countries must invest in population-based cancer registries to measure disease burden and track progress in childhood cancer control”.
The study provides essential benchmarks for monitoring improvements and demonstrates that many more lives can be saved through early diagnosis and effective treatment.
“Our findings support the WHO goal of achieving at least 60% survival for children with cancer by 2030. To reach this target, investment in cancer registries and health infrastructure is critical”, Ms. Daltveit adds.
This research is part of the Cancer Survival in Countries in Transition (SURVCAN-3) project, initiated by the International Agency for Research on Cancer (IARC) in collaboration with the IARC Global Initiative on Cancer Registry Development (GICR).

Scientists develop a smarter mRNA therapy that knows which cells to target
2025-12-15
[New York, NY [December 15, 2025] — Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells—an advance demonstrated in studies in mice that could lay the groundwork for safer, more precise treatments for cancer and other diseases.
The system, called the cell-selective modRNA translation system (cSMRTS), is an engineered form of mRNA designed to activate in specific cell populations. ...
Neuroanatomy-informed brain–machine hybrid intelligence for robust acoustic target detection
2025-12-15
“Current automated STD methods perform well under controlled conditions but degrade sharply in low SNR or with unseen targets, while standalone BCI systems suffer from high false alarm rates. To overcome these limitations, we proposed a hybrid approach that combines the complementary strengths of neural perception and acoustic feature learning,” explained study author Luzheng Bi, a researcher at the Beijing Institute of Technology. The core innovations include (a) Tri-SDANet, an EEG decoding model incorporating neuroanatomical priors from source analysis, (b) a confidence-driven fusion strategy ...
Eight SwRI hydrogen projects funded by ENERGYWERX
2025-12-15
SAN ANTONIO — December 15, 2025 — Southwest Research Institute (SwRI) has received $1.75 million in funding from the ENERGYWERX program to support a set of hydrogen-related projects. The eight projects focus on testing components for the hydrogen industry to improve energy infrastructure and support the use of this clean-burning fuel.
The ENERGYWERX program strives to increase cooperative research activities between the DOE and nonprofits, private companies, utilities, localities and other organizations by accelerating the development of clean energy technologies and ...
The Lundquist Institute and its start-up company Vitalex Biosciences Announces Strategic Advancement of Second-Generation fungal Vaccine VXV-01 through Phase 1 Trials under $40 Million Competitive Con
2025-12-15
The Lundquist Institute (TLI) and its start-up company Vitalex Biosciences (Vitalex) are pleased to announce that the second-generation fungal vaccine candidate known as VXV‑01, which was developed using a proprietary TLI vaccine technology platform, is poised to move forward in development up to and including Phase 1 clinical evaluation — enabled by a major contract awarded to a collaboration consortium of Vitalex and Appili Therapeutics (TSX: APLI; OTCPink: APLIF). The contract from the National Institute of Health’s (NIH) National Institute of Allergy and Infectious Diseases (NIAID) is valued at up to US $40 million. It will support ...
Fine particles in pollution are associated with early signs of autoimmune disease
2025-12-15
A new study has linked air pollution exposure and immune-system changes that often precede the onset of autoimmune diseases.
McGill University researchers analyzing Ontario data found that fine particles in air pollution are associated with higher levels of a biomarker linked with autoimmune diseases, such as systemic lupus.
“These results point us in a new direction for understanding how air pollution might trigger immune system changes that are associated with autoimmune disease,” said Dr. Sasha Bernatsky, a James McGill Professor ...
Review article | Towards a Global Ground-Based Earth Observatory (GGBEO): Leveraging existing systems and networks
2025-12-15
A new peer-reviewed article published in Big Earth Data presents a comprehensive roadmap for building an integrated Global Ground-Based Earth Observatory (GGBEO) to better tackle the escalating planetary environmental and climate crisis. The study argues that unifying existing ground-based, in situ, remote sensing, marine, and airborne observation networks is crucial for meeting the United Nations’ Sustainable Development Goals (SDGs) and for advancing climate science and societal resilience.

Penn and UMich create world’s smallest programmable, autonomous robots
2025-12-15
Researchers at the University of Pennsylvania and University of Michigan have created the world’s smallest fully programmable, autonomous robots: microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each.
Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices.
Powered by light, the robots carry ...
Cleveland researchers launch first major study to address ‘hidden performance killer’ in athletes
2025-12-15
CLEVELAND—Athletes are 2.5 times more likely than the general public to develop nail fungus, according to a study in the Journal of the American Academy of Dermatology. A condition that can disrupt training, change performance and end careers. However, until now, no thorough study has examined how nail fungus affects various sports.
Today, Case Western Reserve University and University Hospitals announced the launch of the first large-scale collaborative study focused on onychomycosis, a chronic fungal infection of the nails, among ...
To connect across politics, try saying what you oppose
2025-12-15
When engaging in a political discussion, talking about what you oppose instead of what you support may make others more open to your views, according to research published by the American Psychological Association.
“In an era of deepening political polarization, our research offers a counterintuitive insight into how we can better communicate across ideological lines: Talk about what you oppose, not what you support,” said lead author Rhia Catapano, PhD, of the University of Toronto.
In a series of experiments involving more than 10,000 participants, the researchers examined how the way people talk about their opinions—specifically, ...
