A Cancer Research UK study showed it could slash bowel cancer patients' risk of death or relapse.
Following an exercise programme after treatment reduced their risk of dying within eight years by 37 per cent.
And it reduced the chance of a patient's cancer growing back within five years by 28 per cent.
Physical activity also appeared to cut the risk for breast and prostate cancers, the two most common types.

'Drugs are approved for less'
Dr Julie Gralow, president of the American Society of Clinical Oncology, said: 'This is the same magnitude of benefit as many drugs.
'Drugs get approved for less than that and they're expensive and toxic, so I would say it's better than a drug.'
Dr Pamela Kunz, of Yale University in the US, said prescribing it was a 'no-brainer'.
The world-first trial involved 889 people from Canada and Australia who had received surgery and chemotherapy for colon cancer, the most common form of bowel cancer.

It affects around 32,000 people per year in the UK and develops in the large intestine.
Half of the participants were given basic exercise advice and the other half were assigned personal trainers and given tailored exercise programmes for three years.

The plan added the equivalent of three to four hours of walking on top of patients' normal daily activity.
At the end of the 15-year trial, people in the personal trainer group were significantly less likely to have relapsed or died.

Study author Dr Christopher Booth, from Queen's University in Kingston, Canada, said: 'These results are clear: an exercise program that includes a personal trainer will reduce the risk of recurrent or new cancer, make you feel better and help you live longer.
'Most patients chose a walking program and could reach their targets by going for a walk of 45 to 60 minutes three to four times per week.
'The benefit was substantial and in some cases exceeded the benefit of many of our very good medical therapies.
'This sets a new standard of care for colon cancer.'

If you start exercising after you get through your treatment you still get the benefits – it's not too late
Dr Julie Gralow
He said that one life was saved for every 14 patients who enlisted in the exercise programme.
It cost an estimated £2,500 per patient over three years and the Canadian government is now looking at including it in hospital care.
Dr Gralow added: 'If you start exercising after you get through your treatment you absolutely still get the benefits – it's not too late.
'Three decades ago it was still the era of doctors being gentle and saying don't overdo it, but we've reversed that and had a major shift in understanding the importance of physical activity.

Kids who vape ‘are THREE times more likely to smoke', drink and take drugs later – and suffer agonising symptoms
Scroll to see which health conditions were also more likely URGENT WARNING Kids who vape 'are THREE times more likely to smoke', drink and take drugs later – and suffer agonising symptoms TEEN vaping is a gateway to heavy drinking and smoking fags and weed, according to research. British experts reviewed results from 56 studies of the impacts of taking up e-cigarettes at a young age. 1 Millions of British youngsters have tried vaping (stock image) Credit: Alamy Millions of under-18s in the UK vape, with one in five having tried it and an estimated one in 25 kids aged 11 to 17 – four per cent – doing it regularly. Advertisement For comparison, an estimated eight per cent of 16 and 17-year-olds smoke cigarettes, according to figures Action on Smoking and Health. New vaping laws have been brought in to try and protect youngsters by imposing age limits, banning disposable devices and cracking down on fruit and candy flavours. The research, led by the University of York and published in the journal Tobacco Control, found young people who use e-cigs are consistently shown to be more likely to take up real smoking when they grow up. On average the risk appeared to be three times higher than in kids who did not vape. Advertisement There are also signs they are more likely to turn to other habits like smoking weed. There was an almost 6-fold higher risk using cannabis, and between a 4.5 and 7-fol higher risk of binge drinking alcohol. Risks of health conditions Results further suggest young vapers might suffer deadly pneumonia, bronchitis, dizziness, migraines, and low sperm count. Asthma was the most common respiratory health outcome, with a 20 to 36 per cent heightened risks of being diagnosed with the condition. Advertisement Three studies showed a link between vaping and suicidal outcomes. Police raid largest spice vapes operation after kids were left hospitalised Study author Dr Greg Hartwell, from the London School of Hygiene and Tropical Medicine, said: 'Our review provides the most comprehensive picture to date on the risks vaping poses to young people. 'In particular, we found consistent evidence around transitions to smoking which, in turn, opens the door to the multitude of harms that conventional cigarettes bring.' Health officials insist vaping is safer than smoking tobacco because it does not contain tar or the same cancer-causing chemicals found in cigs, making it a good quitting aid. But evidence increasingly suggests it is not risk-free and should not be used by people who never smoked in the first place. Advertisement Professor Su Golder, from the University of York, said: 'The consistency in the evidence is striking. 'Across multiple studies, young people who use e-cigarettes are more likely to smoke in the future. 'These findings support stronger public health measures to protect teens from the risks associated with vaping.' Dr Stephen Burgess, from Cambridge University, was not part of the study but added: 'Whether vaping is truly a cause of these behaviours is beyond the scope of this data.'

Junk food flooding young people's social media feeds, says study
Scrolling through social media with the images of burgers, milkshakes and sweets can often make people hungry, but does it have a negative effect as well? A health charity is warning that the constant stream of high fat, salt and sugar (HFSS) content is a big health concern. A poll by Cancer Research UK suggests that children and teenagers are often exposed to unhealthy food content online, with young people interacting more with the content when it is shared by charity is calling on the government to do more to protect children and young people from "harmful marketing". The charity surveyed more than 4,000 young people aged 11 to found around half saw unhealthy food or drink products on social media posted by businesses or influencers in the last four in ten (39%) said they interacted with these posts by liking, commenting or number was higher for influencer content than it was for adverts from part of the study, 43 young people also took part in discussions around the topic and reported that seeing certain foods would make them particularly hungry."At least every two minutes that I'm on Instagram I'd see at least one food-related post," said one 15-year-old participant. Another, aged 11, said:"[There] is a giant cookie bowl that also keeps showing up," she said. "When I see it, I feel like ordering a dessert and I feel really hungry." High saturated fat, sugary and salty foods (such as cakes, biscuits, chocolate, crisps) can be eaten occasionally. The problem is eating too much of these foods can have big health impacts. The charity says that eating too much of these foods increases the likelihood of children becoming overweight which can lead to further health problems. In January 2026, new laws are to be bought in by the government to ban paid-for online advertising of specific high in fat, salt and sugar products, including on social media, alongside new rules for junk food ads on TV. Cancer Research UK says these changes have already faced delays."Advertising can shape what children eat, so the UK Government must help create an online environment that empowers, rather than undermines, healthy changes," Liv Cheek, prevention policy manager for the charity said.

Cancer charity finds children 'more likely to engage with junk food posts from influencers'
We are guilty of exposing our kids to social media but it could be having a huge impact on their diet We are all guilty of treating our kids to a cheeky McDonald's or bringing our niece or nephew to the KFC drive-thru. We are also guilty of letting our young people scroll social media, and perhaps engage with top influencers. So, what if the two things combined, and youngsters were actually more likely to engage with junk food posts shared by social media personalities? Well, apparently that it what is happening, according to Cancer Research UK, who say children and teenagers are being bombarded with videos and pictures of unhealthy food online, the leading charity's polling suggests. And youngsters are more likely to engage with content about junk food if it is shared by influencers, they added. The charity surveyed 4,000 children and young people aged 11 to 21 across the UK and some reported that seeing content about food high in fat, salt and sugar made them feel tempted or hungry. "A giant cookie bowl keeps showing up, when I see it, I feel like ordering a dessert and I feel really hungry," an 11-year-old told the charity. A 15-year-old added that "at least every two minutes that I'm on Instagram I'd see at least one food-related post". What's more, 52 per cent saw unhealthy food and drink products from either businesses or influencers on social media in the last month, while almost four in 10 said they engaged with these posts by commenting, liking or sharing. They were also more likely to interact with a post from an influencer compared to a business. Cancer Research UK said that ministers must do more to protect young people from "harmful marketing that could increase their risk of obesity and cancer in the future". New laws, which come into force next year, will end paid-for advertising, including online, of specific foods which are high in fat, sugar and salt. The charity said that it is important for the implementation of the legislation to go ahead as planned after repeated delays. And it warned that not all exposure to junk food will end when the new laws come into place as there will still be online advertising loopholes. Liv Cheek, prevention policy manager at Cancer Research UK, said: "Being overweight or obese is the second biggest cause of cancer in the UK after smoking, and rates among young people are rising. "Advertising can shape what children eat, so the UK Government must help create an online environment that empowers, rather than undermines, healthy changes. "Planned restrictions on junk food advertising online are a vital step to protect young people's health. These measures must be properly enforced and strengthened by closing any remaining gaps in the online marketing rules." Join the Daily Record WhatsApp community!

A Government spokesperson said: "Obesity robs children of the best start in life and sets them up for a lifetime of health problems, which costs the NHS billions. "The junk food advertising restrictions on TV and online are a crucial part of our Plan for Change to raise the healthiest generation of children ever." The Government claims that by reducing children's exposure to junk food advertising, they will remove "up to 7.2 billion calories from UK children's diets each year and deliver around £2 billion in health benefits."
