Doctors warn millions of people will be diagnosed with stomach cancer because of common infection
Called Helicobacter pylori (H. pylori), infection with the bug is now estimated to cause 76 per cent of stomach cancers worldwide.
Experts warn that many people infected with the bacteria—which infests the lining of the stomach and causes damage to tissue that can lead to cancer—show no obvious symptoms beyond relatively common ailments like indigestion, bloating or nausea.
The team is now calling for increased screening for the bacteria, which can be detected in blood and breath test or via a stool sample in a bid save lives.
Scientists from the International Agency for Research on Cancer (IARC)—part of the World Health Organisation —warned if nothing was done nearly 12million people across the globe born between 2008 and 2017 will develop stomach cancer due to H. pylori.
This, they said, represented just over three quarters of all cases of the cancer.
H. pylori is thought to be spread from person to person via contaminated food and water as well caring for those who become ill.
Studies have previously found 40 per cent of Britons are infected with H. pylori, but this is thought to be on the decrease.
The vast majority of these patients—between eight-to-nine out of 10—will show no symptoms meaning they have no idea they are infected.
H. pylori can rarely cause the development of painful stomach ulcers which is usually when most patients learn they are infected.
While the IARC scientists said the majority of the predicted 12million stomach cancer cases linked to the bug will be in Asia, 2million will develop in the Americas and 1.2million in Europe.
Data from British charity Cancer Research UK (CRUK) suggests 41 per cent of the UK's 6,500 annual stomach cancer cases are caused by H. pylori, about 2,700 cases a year.
Studies suggest being infected with the bacteria increases the risk of developing stomach cancer six-fold, although appropriate treatment like antibiotics, dramatically reduces this.
Writing in the journal Nature Medicine, the IARC scientists called for greater investment in population testing for H. pylori to find those silently infected with the bacteria and offer them treatment.
In the study itself, the team examined current rates of stomach cancer in 185 countries in 2022 and used that to project the number of cases in the coming years.
They also found 75 per cent of stomach cancer cases could be prevented globally by the introduction of screening programmes.
Dr Jin Young Park, an author of the study and leader of the gastric cancer prevention team at IARC, said: 'It is essential that health authorities make gastric cancer prevention a priority and accelerate efforts to control it by planning pilot and feasibility projects, including H. pylori screen-and-treat programmes.'
But CRUK said Britons should not be too concerned about potential infection with H. pylori as it was not a particularly common bug in the UK.
Instead, the charity's health information manager Dr Rachel Orritt said the public needed to beware of more preventable lifestyle factors that increase stomach cancer risk.
'Although this is an important issue worldwide, in the UK other preventable factors cause more cancer cases,' she said.
'Ways to reduce your cancer risk include stopping smoking, keeping a healthy weight, cutting down on alcohol and eating a healthy, balanced diet.'
The charity estimates that just over half (54 per cent) of all stomach cancers are preventable.
CRUK also noted that stomach cancer cases in the population have fallen by more than quarter over the last decade and are projected to fall further.
The main symptoms of stomach cancer include heartburn or acid reflux, having problems swallowing, feeling or being sick, indigestion and burping and feeling full very quickly when eating.
These symptoms are common and usually caused by other conditions but patients who have had them for over three weeks should contact their GP for advice,
Other symptoms include loss of appetite or losing weight without trying, stomach pain, a lump feeling at the top of the stomach and feeling very tired.
About 18 Britons and 83 Americans are diagnosed with stomach cancer each day.
The disease kills just over 4,200 patients in the UK each year, with the death toll rising to nearly 11,000 in the US.
Only about one in six patients with stomach cancer (17 per cent) are expected to still be alive 10 years after their diagnosis.
About one in 92 men and one in 170 women in the UK are estimated to develop stomach cancer in their lifetime.

Notoriously cruel Roman emperor may have been a plant nerd, archaeologists find
The notoriously cruel Roman emperor Caligula may have been quite knowledgeable about medicinal plants, a new study suggests. Emperor Gaius, nicknamed Caligula, was the third ruler of the Roman Empire from 37AD until his assassination in 41AD. Surviving records of the tyrant's short reign hint that he indulged in an extravagant lifestyle of megalomania, sadism and sexual perversion. A new study, published in the journal Proceedings of the European Academy of Sciences and Arts, suggests that the dictator may have been familiar with the pharmacology of ancient times. 'He's dismissed as a madman, perhaps rightly so, but we show he very likely knew something about hellebore and pharmacology in general,' Trevor Luke, an author of the study from the Yale Ancient Pharmacology Program, said. Researchers assessed a brief anecdote about Caligula originally reported by historian Suetonius in The Twelve Caesars. The second century collection of biographies of Roman rulers provides evidence that 'Caligula, while a tyrant, was more knowledgeable about medicine than has been previously understood'. The text tells the story of an unnamed Roman senator suffering from an unspecified ailment who takes a leave of absence to the Greek spa town of Antikyra, hoping his health would improve with treatment using the flowering plant hellebore. But when the senator asks Caligula to extend his leave, the emperor has him executed, quipping that 'a bloodletting was necessary for one whom hellebore had not benefited in all that time'. The study by Yale researchers sheds new light on the passage, providing context about Antikyra's place in the Roman Empire and Caligula's familiarity with plant medicines. "Our work suggests that Antikyra functioned as a kind of Mayo Clinic of the Roman world – a place where affluent and influential Romans visited for medical treatments not widely available elsewhere," Andrew Koh, another study author, explained. "It was known for hellebore treatments and little else. It's an example of ancient medical tourism. Roman bigwigs travelled there for treatments the same way that the rich and powerful visit Rochester, Minnesota, to avail themselves of the latest medical techniques and therapies available at the Mayo Clinic,' Dr Luke said. Antikyra, on the Gulf of Corinth in the Phocis region of central Greece, was famed for its association with unique hellebore treatments for epilepsy and mental illnesses. Texts point to two varieties of the plant – white hellebore for treating afflictions of the head and black hellebore for clearing the bowels. The port town was renowned for the perceived efficacy of special hellebore potions used to treat melancholy, insanity, epilepsy, and gout. Since the term "hellebore" was used to reference various plants, examining the plant's historical uses has been difficult. Researchers suspect the spa town held personal appeal to Caligula as historical records hint that he likely suffered from epilepsy and insomnia that Antikyran potions were believed to cure. 'It's possible that Suetonius is wrong and Caligula wasn't ordering the man's execution but simply prescribing an alternative treatment that he had read about or knew from his own experience," Dr Luke said.

Music meets nature in Surrey care home study
A care home has appointed a 'Musician-in-Residence' in a pioneering study exploring how outdoor music-making can benefit older people and those with at the Huntington & Langham Estate in Hindhead, Surrey, enjoy outdoor activities from music scholar Stuart Wood as part of the project examines how music and nature together can boost wellbeing, social connection, and emotional expression in care Wood said he hoped to understand how playing music outdoors "can foster social connection, emotional expression, and overall health in later life." The NHS says music in a care setting can help "reduce anxiety and depression, help maintain speech and language, is helpful at the end of life, enhances quality of life and has a positive impact on carers".It is also acknowledged that spending time outdoors can have a positive impact on the cognitive, emotional, and physical wellbeing of older people. Mr Wood's project explores how outdoors music can further enhance social connection, uplift mood, and support mental and physical health within care home communities. The study will form part of his Visiting Research Fellowship at Bath Spa University's School of Music and Performing will also share insights from this project with music students and post-graduate Wood said: "What we don't know is what happens when you bring together playing percussion and doing that outdoors, so this project is asking that question."Sarah Chapman, the director of Huntington & Langham Estate, said she was "curious about the possibilities and the benefits of combining music and nature".Findings from this week-long pilot study may inform a larger, international research project planned for later this year, with results expected to be published in 2026.

Beach BBQ warning after toddler burns feet on Lincolnshire beach
A dad is warning people about the dangers of using disposable barbecues at the beach after his toddler burned his feet on hot sand - six hours after the family had cooked 39, from Nettleham in Lincolnshire, initially thought his son Edison had been stung by an insect after he started screaming in pain during a day trip to Anderby Creek family had not realised the sand would stay dangerously hot for such a long time, but it soon became clear the two-year-old had burned himself "really badly"."If I could just stop one person from getting their feet burnt, that would be a great message," said Lee. Warning: This story contains an image of burn injuries Lee said he was urging people to think twice before using disposable barbecues at the beach this summer, after his family's ordeal in August 2024."I put his feet into the sea water and I just suddenly went into panic mode, realising this is really serious, and he's not just burned, he's burned really badly," said was treated by specialist burns doctors at Queen's Medical Centre in toddler had to have sand removed from his feet, under general anaesthetic, and could not stand up for two weeks."He was just absolutely beside himself because it was so painful," said Lee."I've played it over in my head so much, saying I wish it was me and not Edison, but really, I just wish it couldn't have happened to anyone. It was horrible." Dr Abhishek Potturi, a paediatrician at Lincoln County Hospital, said he did not advise using disposable barbecues at the beach, and anyone doing so should take great said sand retained a lot of heat and had the potential to cause third-degree burns."Heat gets trapped in the sand and it can stay there for a long period of time. It can take hours to cool, or even overnight," said Dr Potturi. The family had used their disposable barbecue at lunchtime, in an area away from where their children were playing, and disposed of it immediately they later discovered the sand was still hot, Lee said one relative cooled the area with water and the sand "erupted like a volcano"."It was really quite scary how the sand reacted, which just shows how hot that sand was," he has not been left with any lasting damage, and Lee said he felt "so relieved"."It was like I'd won the lottery, I just couldn't believe it," he added. Earlier this year, Lincolnshire Fire and Rescue said disposable barbecues had become a "significant issue" for Moss, an area manager with the service, called for people to be "really vigilant", saying said fires could start when the single-use trays were used in the wrong setting or not discarded properly.
