Just 10 minutes of exercise can trigger powerful anti-cancer effects

As people return to gyms or start new fitness routines in the new year, new research suggests that even a short burst of intense exercise could play a role in protecting against cancer. Scientists report that as little as 10 minutes of hard physical activity may help slow cancer growth.

The study found that brief, vigorous exercise quickly changes the mix of molecules circulating in the bloodstream. These rapid shifts appear to suppress bowel cancer cell growth while also speeding up the repair of damaged DNA.

How Exercise Changes the Bloodstream

Researchers at Newcastle University discovered that exercise raises the levels of several small molecules in the blood. Many of these molecules are known to reduce inflammation, support healthy blood vessels, and improve metabolism.

When scientists exposed bowel cancer cells in the lab to blood containing these exercise-driven molecules, they observed widespread genetic changes. More than 1,300 genes shifted their activity, including genes involved in DNA repair, energy production, and cancer cell growth.

Published in the International Journal of Cancer, the findings help clarify how physical activity may lower bowel cancer risk. The research shows that exercise sends molecular signals through the bloodstream that influence genes controlling tumor growth and genetic stability.

The results add to growing evidence that staying physically active is an important part of cancer prevention.

New Possibilities for Cancer Treatment

Dr. Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead author of the study, said: “What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.

“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.

“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”

Slowing Cancer Growth at the Cellular Level

The research team found that exercise increased the activity of genes that support mitochondrial energy metabolism. This helps cells use oxygen more efficiently.

At the same time, genes linked to rapid cell division were turned down, which may make cancer cells less aggressive. Blood collected after exercise also boosted DNA repair, activating a key repair gene known as PNKP.

The study included 30 volunteers, both men and women between the ages of 50 and 78. All participants were overweight or obese (a risk factor of cancer) but otherwise healthy.

Each volunteer completed a short but intense cycling test that lasted about 10 minutes. Researchers then collected blood samples and examined 249 proteins. Thirteen of those proteins increased after exercise, including interleukin-6 (IL-6), which plays a role in repairing damaged DNA.

Why Even One Workout Matters

Dr. Orange, a Clinical Exercise Physiologist at The Newcastle upon Tyne Hospitals NHS Foundation Trust, said: “These results suggest that exercise doesn’t just benefit healthy tissues, it may also create a more hostile environment for cancer cells to grow.

“Even a single workout can make a difference. One bout of exercise, lasting just 10 minutes, sends powerful signals to the body.

“It’s a reminder that every step, every session, counts when it comes to doing your best to protect your health.”

Bowel Cancer Rates and Physical Activity

Bowel cancer is the 4th most common cancer in the UK, after breast, prostate and lung cancer.

In the UK, one person is diagnosed with bowel cancer every 12 minutes, adding up to nearly 44,000 cases each year. Someone dies from the disease every 30 minutes.

Researchers estimate that regular physical activity lowers bowel cancer risk by about 20%. Exercise does not have to mean gym workouts or sports. Walking or biking to work, along with everyday activities such as gardening or cleaning, can also contribute.

Looking ahead, the research team plans to examine whether repeated exercise sessions lead to long-lasting biological changes. They also aim to study how exercise-related effects interact with common cancer treatments such as chemotherapy and radiotherapy.

As cost of living bites, one of the things slipping may be fitness goals

As cost of living bites, one of the things slipping may be fitness goals

For Hobart teacher Mary Holton, health means everything. 

She started feeling the squeeze from cost-of-living pressures when fuel prices spiked again.

“Going out for just fitness alone was a bit much,”

she said.

Many Tasmanians are feeling cost-of-living pressures in a very physical way, with locals saying exercise routines are being dropped, health appointments delayed and wellbeing pushed to the bottom of the list as budgets tighten.

Ms Holton relies on multiple physiotherapy sessions each week, but says paid fitness classes simply are not an option.

That costs … so to actually go to other classes as well, it’s out of my budget really.

National data shows that almost half of Australians already fall short of minimum physical activity guidelines, and rising prices are making even basic care unaffordable for many.

Consultant clinical psychologist academic Kimberley Norris says this is exactly how unhealthy patterns begin.

“We tend to focus on the most stressful thing first … and health is one of those things we don’t think about until things go wrong,”

Professor Norris said.

For Ms Holton, going to a free workout group in her local community was a game-changer.

“Came down and absolutely loved it. It’s really nice to have a group and it just keeps growing,” she said.

Finding a free exercise group has drastically improved her health, as noted by her GP, and she is part of a growing trend.

Free exercise classes become a lifeline

At a community exercise class in South Arm, south-east of Hobart, the mood is upbeat, with laughter, movement, and a sense of relief. 

Participation has more than doubled in the past year, with more than 100 Tasmanians now involved.

Trainer Ollie Mathewson said the surge was unmistakable.

“It’s free of charge for everybody … and over the last 12 months I’ve noticed a lot more people starting to come along,”

he said.

Across greater Hobart, free and low-cost alternatives are multiplying and include walking groups, community-run circuits, and morning and afternoon fitness meet-ups. 

Tasmanians are increasingly organising their own solutions.

Mr Mathewson said connections drive outcomes.

A lot of people talk about weight and strength, which are obviously insanely important, having other people there to push you single every week makes it a hundred times easier.

Professor Norris said one’s health can be prioritised for free.

“What we know about health is, it’s more about sustainable wellbeing, it’s about quality of life,” she said.

“So rather than focusing on how much you can deadlift, how far you can run, it’s about how your life has improved and how close your life is to the way you want to live it.”

She said free options were vital because once people stop moving, it becomes harder to start again.

If we develop routines in which health is not a priority, then we almost get stuck in this cycle of health always being last.

Health appointments being delayed or dropped

For some Tasmanians, the financial pressure is forcing even tougher choices.

Amy Dakin, who lives with a compromised immune system, often has no choice but to delay essential care.

“My health needs to be prioritised, but your bills come first, really,” she said.

Jordyn Rowbottom has seen the same pattern around her.

“People are being forced to cut what they can access,”

she said.

Professor Norris warns that these short-term decisions can create long-term harm, not just for individuals, but for the broader health system.

She said the combination of financial pressure and reduced physical activity would create a public health challenge.

Trainers adapting to shrinking budgets

Personal trainer Nickola Orr works with clients across different income levels, ages and needs. 

She said affordability now shapes almost every program she designs.

“You want to make sure they can get as much help as they can within their price range,”

she said.

With the median individual spend on fitness in Tasmania sitting at almost $600 last year, Ms Orr said the warning signs were already visible.

“We’re going to see more results of long-term neglect; higher injuries, more need for mental health assistance. It’s going to snowball.”

Her concerns echo Professor Norris’s academic findings that once healthy routines break down, the consequences ripple for years.

“The changes are very small … while they add up over time, there is no immediate impact,”

Ms Orr said.

Calls for more free and low-cost options

Mr Mathewson hopes the success of free community classes will inspire governments and private operators to expand accessible fitness programs.

“More free options would be a great thing. There are a few now, but there should be more,” he said.

The Tasmanian government has said it will release its 20-year preventive health strategy this month, titled The Health Revolution.

A Department of Health spokesperson said the strategy “will address the broader social, economic, and environmental factors that influence health and wellbeing”.

“Specific issues about access to health services and programs are being considered through the Access to Health Services project, a Commonwealth-State partnership.

The Health Revolution will complement that project by addressing the root causes of poor health and the underlying conditions to make it easier for Tasmanians to live well.

El Monte women’s fitness studio focuses on empowerment and community

EL MONTE, Calif. (KABC) — A boutique fitness gym in the San Gabriel Valley is focused on women’s empowerment, offering everything from dance fitness to pilates, yoga, zumba and circuit training. It’s called “Beastin Beauties” in El Monte.

Boutique fitness spaces here, it doesn’t exist here, so I needed to have this for the people in my community here, where I grew up,” said owner Jay Armada.

Members love working on their health and fitness alongside other women.

“You walk in and you feel like you’re able to let loose and inhibit it in a way that you don’t find in other places,” said member Esmeralda Cabral.

“It takes away the stresses of being in a space where you may feel judgment from others. And there’s a certain level of comfort as a woman that you wanna be able, especially if you’re starting a health journey or you’re reigniting it, you wanna have the comfort of being around under supportive women,” said member Ruby Rose Yepez, who also teaches yoga at the studio.

Women empowerment has been the theme all along, from Jay’s humble beginnings…

I want people to feel what I felt when I was going through my own journey. I had lost ninety-three pounds in a whole year and I just wanted everyone to feel that,” said Armada.

…to a huge setback in 2020 when the gym’s previous location burned down in a fire.

I thought I didn’t wanna do it anymore. Maybe it was a sign from God that you should just quit. But my community held me up and they just really made me believe in it again,” said Armada.

Now, her business is thriving, and she was just named the city’s Woman of the Year!

Community and connection here in this space is super, super important. Jay is not just about bringing people here for health. She brings people here to build the connections so that they feel that they’re part of a community,” said Yepez.

“You build a connection without even really trying. You’re all experiencing the same moments together. There’s always just so much fun happening,” said Cabral.
