Imagine this: a single exercise session might actually lower cancer cell growth by almost a third. Sounds pretty awesome, right?

A new cancer research study on exercise by scientists from the Edith Cowan University found that just one workout can seriously slow down how fast cancer cells grow. Researchers dug into how physical activity affects cancer risk at the cellular level and discovered that it triggers some powerful changes, like boosting the immune system and releasing substances that can help keep cancer cells in check.

The findings of the study have been published in the journal Breast Cancer Research and Treatment.

The cool part? You don’t need to be a gym fanatic or do marathon training. Even a single bout of moderate exercise for cancer prevention seems to kick-start this anti-cancer effect.

"Breast cancer is the leading cause of cancer-related death in women, highlighting the need for strategies to mitigate recurrence and mortality. We examined the effects of a single bout of resistance training (RT) versus high-intensity interval training (HIIT) on anti-cancer myokines and in vitro cancer cell suppression," the researchers have said.

"A single bout of RT or HIIT can increase levels of anti-cancer myokines and reduce the growth of MDA-MB-231 cells in vitro in survivors of breast cancer, potentially contributing to a lower risk of recurrence. This highlights the importance of exercise as a treatment with promising anti-cancer effects," they have concluded.

Examples of resistance training and HIIT workouts
Resistance training (also called strength or weight training) is all about building muscle and making your body stronger. You can use dumbbells, resistance bands, kettlebells, or even just your body weight. Think squats, push-ups, lunges, planks, and bicep curls. It’s not just for bodybuilders—it helps boost metabolism, protect your joints, and even reduce your risk of certain cancers.

Then there’s HIIT (High-Intensity Interval Training)—basically short bursts of hard work followed by quick rests. A classic example? 30 seconds of jumping jacks, 15 seconds rest, then 30 seconds of burpees. You repeat this pattern for 15–30 minutes. Other moves include mountain climbers, high knees, jump squats, or sprint intervals on a bike or treadmill.

How exercise helps cut your cancer risk (and it’s easier than you think)
When you think about ways to reduce your cancer risk, your mind probably goes to eating healthy, quitting smoking, or avoiding too much sun. And while those things absolutely matter, there’s another powerful habit that often gets overlooked: exercise.

Yep, just moving your body regularly can make a real difference when it comes to preventing cancer. And no—you don’t need to be running marathons or spending hours at the gym to see the benefits.


So how does it work?
Well, exercise helps in a few ways. First, it boosts your immune system, which plays a huge role in fighting off abnormal cells that can turn cancerous. It also reduces inflammation in the body—a key factor in cancer development. Plus, staying active helps control body weight and hormones like estrogen and insulin, both of which are linked to certain cancers when they’re out of balance.

The best part? You don’t have to do a ton to make an impact. Research shows that just 30 minutes of exercise a day, five times a week, can be enough to start protecting your health. Even breaking it into smaller chunks—like 10-minute walks after meals—still counts.

And here’s something wild: a recent study even found that a single workout can slow the growth of cancer cells by up to 30%. So yes, even one session can make a difference.

The takeaway? Exercise isn’t just about looking fit or losing weight. It’s one of the most accessible and natural tools we have to protect ourselves from serious diseases like cancer. No pills, no fancy gadgets—just your body in motion.

So whether you’re walking the dog, biking through the park, or just dancing around your kitchen, you’re doing something great for your long-term health. Keep moving—you’ve got more power than you think.
