Exercise As Medicine: How Physical Activity Supports Cancer Prevention And Recovery
Last Updated:
Recent research has shown how regular exercise and movement can play a role in reducing cancer risk. An expert decodes how physical activity can greatly help cancer patients.
Aerobic exercise and strength training aid cancer prevention and recovery.
In the evolving world of cancer care, exercise is emerging as more than just a lifestyle choice – it’s becoming a pillar of prevention and recovery. While traditionally associated with weight control and cardiovascular health, regular physical activity is now backed by strong scientific evidence for its role in reducing cancer risk, improving treatment outcomes, and enhancing quality of life during and after therapy.
Dr. Devesh S Ballal, Consultant – Surgical Oncology & Robotic Surgery, Manipal Hospital Old Airport Road, Bengaluru, answers how exercise plays a role in cancer prevention.
How does regular physical activity impact cancer prevention, according to current research?
Dr Ballal said, “There are numerous trials that support the fact that exercise lowers the risk of cancer. Exercise reduces insulin resistance and inflammation, enhances immune surveillance, and helps control systemic inflammation – all of which play a role in cancer development.”
He added, “Obesity, aside from its known impact on heart health, is a significant risk factor for nearly 13 types of cancer, with particularly strong links to breast, uterine, and colorectal cancers. A large-scale study published in the British Journal of Sports Medicine, involving 85,000 individuals, revealed that regular physical activity can reduce cancer risk by up to 26%.”
Is there scientific evidence linking specific types of exercise to reduced cancer risk?
Dr Ballal said, “Aerobic exercise and strength training both contribute to cancer prevention and are also beneficial during treatment and recovery. The American Cancer Society recommends that adults aim for at least 300 minutes of moderate-intensity exercise per week. Additionally, recent research from Tata Memorial Hospital shows that yoga, especially for breast cancer patients, provides tangible physical and mental health benefits.”
How safe is it for patients to exercise during cancer treatment, like chemotherapy or radiation?
Contrary to popular belief, bed rest is rarely beneficial. Supervised exercise regimens are encouraged even during chemotherapy and radiation. Dr Ballal suggested, “While treatment-related fatigue may limit intensity, staying active helps preserve muscle mass, reduce fatigue, and improve overall well-being. Importantly, exercise plans should be customized to individual capacity and limitations to ensure safety and effectiveness.”
What role does physical activity play in improving long-term outcomes and survival rates?
Exercise is fast becoming a central component in long-term cancer care. Dr Ballal said, “A landmark study in the New England Journal of Medicine found that a structured exercise routine for patients recovering from colon cancer surgery and chemotherapy reduced the risk of recurrence by 28% and the risk of death by 37%. That’s a benefit comparable to chemotherapy, making movement a vital form of medicine in itself.”
Are there standard exercise guidelines for cancer patients or survivors?
Dr Ballal noted, “Yes. Guidelines from bodies like the American Cancer Society and the National Comprehensive Cancer Network (NCCN) offer practical frameworks for integrating exercise into recovery plans. The NCCN also outlines which patients may require medical clearance before beginning an exercise regimen. For example, individuals with osteoporosis should avoid high-impact activities due to fracture risk.”
Does exercise help reduce the side effects of cancer treatments, such as fatigue or neuropathy?
Clinical trials have demonstrated that regular, supervised physical activity can reduce cancer-related fatigue more effectively than medication alone. Dr Ballal said, “Exercise also improves balance and coordination, which helps manage chemotherapy-induced peripheral neuropathy. Simply put, movement plays a powerful role in easing side effects and promoting overall recovery.”
Physical activity is no longer just a supportive tool – it’s a crucial aspect of cancer care. With mounting evidence showing its ability to prevent cancer, improve treatment outcomes, and enhance quality of life, exercise is now recognised as a vital prescription in oncology – one that empowers patients to take active control of their healing journey.

The NHS has reignited the hybrid working debate – but WFH isn’t the health risk, this is
The latest NHS exercise guidance reinforces what we’ve been preaching for years: hitting that 150-minute weekly movement target isn’t necessarily a get-out-of-jail-free card. It states that prolonged sedentary time is independently harmful, even for those of us who diligently carve out time for the gym. Verbatim, it says ‘prolonged sitting is harmful, even in people who achieve the recommended levels of moderate to vigorous physical activity’.
Chief Medical Officer Professor Sir Chris Whitty has been especially vocal about how detrimental it could be, highlighting hybrid working as a potential health hazard. ‘Without wanting to exaggerate, I think it’s important people think through, for example, hybrid working means quite a lot of people could very easily do very little other than leave their homes, where previously people would be routinely going to work, and that often meant at least some physical [activity],’ he said at a briefing.
I understand his logic, but it’s pretty reductive. Working from home isn’t the villain here – working from one chair is.
When we label remote work as “bad for your health”, we risk throwing the baby out with the bath water. In reality, for many – certainly the whole of the Women’s Health office, but also my less-fitness-conscious sister and stepdad, plus my entire friendship group – working from home often means being more active. It means more time to fit in a lunchtime run, to get some steps in before work, or to run some errands on a quick break.
On the other hand, plenty of office workers are more sedentary than they are at home. They sit at a desk for nine hours straight before driving home, whether to be seen to work tirelessly in front of their manager, or simply because they’re pulled from pillar to post in an office setting. For those who do have an office commute, eliminating that often stressful period of the day allows for better sleep, and more time for the movement breaks we need to break up the dreaded sedentary time. Not to mention that many commutes are almost entirely sedentary on a train/tube/bus.
The potential problem, the advice suggests, is the lack of incidental movement – the walk to the train, the stroll to a meeting room, or heading out for lunch – that’s naturally baked into your day when you’re in the “official” office. Without a commute or a day in the office, the onus is on you to manufacture movement in.
Without sounding evangelical, I’ve made this a non-negotiable part of my day. On WFH days, I work out or walk every single morning before I log on, and walk again every evening, even if just a lap around the block. During the day, I have a personal rule: if I’m downstairs, I use the upstairs toilet (and vice versa). Sounds excessive, but it forces me to activate my muscles and add to my step count every few hours.
Beyond that, the options are endless if you’re intentional. Use a standing desk or put your laptop on a kitchen worktop during calls. Take every phone meeting on foot, pacing your hallway if necessary. Set a timer to stand up every 30 mins to stretch, grab a glass of water, or do a quick load of laundry.
We don’t need to return to the office to be healthy; we need to bring movement back into our homes. The goal: to stop being professional sitters.

A Strength Coach Says These Two Exercises Are All You Need to Build Stronger Shoulders
If you ask anyone on the gym floor how to grow a bigger set of shoulders, you’ll probably find that no two answers are the same. In between front raises, upright rows, machine presses and cable raises, shoulder day can quickly become a long list of exercises.
However, fitness creator and coach Eric Evans, also known on social media as Average to Jacked, thinks most lifters are overcomplicating things. He says that if he had to start from scratch after over a decade of training, he’d strip his shoulder workouts back to just two simple moves.
‘If I had to start over today, I’d build my shoulders with just two movements: a lateral raise and also a rear delt fly,’ he explains.
According to Evans, the reason for this isn’t because those exact exercises are magic, but because they work the correct movement pattern for the muscle.
‘Your body doesn’t know the name of the exercise you’re doing,’ he argues. ‘It really only knows the fundamental movement pattern you’re asking it to perform and also the amount of tension you’re placing on the muscle.’
So, you don’t have to perform cable lateral raises if your gym only has dumbbells, or use a reverse pec deck if you’d rather do bent-over rear delt flyes. As long as you’re training the same movement pattern and progressing the move with intensity or volume, you’ll achieve a similar result.
According to the coach, lateral raises deserve a place in your programme because they primarily target the side delts, helping create broader-looking shoulders and a more pronounced ‘V-taper’. Rear delt flyes train the back of the shoulders to create a rounder, more 3D physique.
‘I’m not including anything for the front delts, and that’s intentional,’ he says. ‘Your front delts are already heavily involved every time you do pressing exercises for your chest.’
For most lifters already bench pressing, incline pressing or overhead pressing regularly, he argues the side and rear delts are more likely to be the limiting factor.
‘I don’t think the front delts are what’s holding their shoulders back. I think it’s the side and rear delts,’ he adds.
He recommends focusing on controlling every rep, and avoiding using momentum to swing the weight. He also suggests working in the 8-15 rep range, adding reps until you reach the top of the range before increasing the load and repeating the process – also known as progressive overload.
‘You definitely don’t need to hit your shoulders from 10 different angles,’ he says. ‘You just need to consistently train these two movement patterns, push them hard and then gradually get stronger over time.’
The Bottom Line
Research suggests muscle growth is driven more by sufficient training volume, progressive overload and proximity to failure than by constantly changing exercises and programme hopping. In fact, that could hinder it. So if your shoulder workouts have become jam-packed with unnecessary variations, simplifying your approach may be exactly what helps you make more consistent progress in the long term.

80-year-old fitness icon Joan MacDonald reveals her simple exercise for a stronger, more stable core
Joan MacDonald didn’t enter a gym until she was 70. Really. Since then, the 80-year-old has transformed her health by losing three stone and building significant muscle, and now coaches other women through her training platform, Train With Joan, which she launched to help others boost their fitness at any age.
The premise of her app is simple: minimal-equipment workouts built around no-fuss, effective exercises that can be done anywhere. One ‘powerful core and stability exercise’ she swears by is alternating bodyweight clock taps. ‘This movement helps strengthen the muscles that keep you stable, balanced and moving well as you age,’ Joan explains.
Bodyweight clock taps benefits
Think they look too simple? That’s the point. Joan is adamant that ‘You don’t need complicated workouts to start getting stronger. Sometimes the most effective movements are the simple ones you do consistently.’
According to Joan, regularly performing bodyweight clock taps help:
- ‘Strengthen your core which supports your spine and reduces strain on your lower back.
- ‘Improve balance and coordination, helping you stay steady on your feet.
- ‘Increase hip stability, which supports your knees and joints.
- ‘Build functional strength for everyday movements like stepping, turning and reaching.
- ‘Help reduce fall risk by improving control and body awareness’
How to do bodyweight clock taps
Find a demo from Joan above, along with instructions for how to do them with proper form below.
- Stand on one leg with a slight bend in your supporting knee and brace your core.
- Keeping your hips level, reach your free foot forward to lightly tap the floor in front of you (12 o’clock), then return to the centre.
- Continue tapping to different “clock” positions—such as 3, 6 and 9 o’clock—maintaining your balance and control throughout.
- Complete all reps on one leg before switching sides.
Form tip: Move slowly and focus on staying stable. The goal is controlled movement, not how far you can reach.
How many reps and sets to do
Joan shares her advice, according to your fitness level.
- Beginners: ‘3 taps per leg x 8-10 reps’
- Intermediate: ‘3 taps per leg x 10-12 reps’
- Advanced: ‘3 taps per leg x 12-15 reps’
