SmartCancer | OneDayMD Integrative Oncology Research

Last updated: November 2026

Exercise is more than a fitness recommendation for people living with cancer. It is an important component of supportive oncology, helping patients maintain physical function, strength, cardiovascular fitness, mobility and independence.

Cancer and its treatments can contribute to fatigue, muscle loss, reduced physical capacity, neuropathy, impaired balance and psychological distress. Without appropriate physical activity and rehabilitation, some patients experience progressive de-conditioning that affects their everyday lives.

Exercise oncology is the growing field that studies how physical activity and structured exercise can support people before, during and after cancer treatment.

This guide examines the clinical evidence, exercise guidelines, resistance training, muscle preservation, prehabilitation, cancer-related fatigue, special safety considerations and rehabilitation throughout the cancer journey.

Our objective is to translate exercise-oncology research into practical, evidence-informed guidance while recognizing that exercise must be adapted to each patient's cancer, treatment, physical capacity and medical condition.

Key message

Avoiding inactivity and maintaining physical function should be part of comprehensive cancer care.

Evidence supports appropriately tailored aerobic and resistance exercise during active treatment with curative intent. Exercise can reduce fatigue and help preserve physical fitness and strength.

However, these benefits should not be confused with proof that exercise alone treats cancer, prevents recurrence or increases survival in every cancer setting.

1. What Is Exercise Oncology?

Exercise oncology is the scientific and clinical field concerned with the role of physical activity, structured exercise and rehabilitation in cancer prevention, treatment support and survivorship.

It examines how different forms of movement influence physical fitness, muscle strength, fatigue, metabolic health, psychological wellbeing and quality of life in people affected by cancer.

It also investigates the possible biological effects of exercise on inflammation, insulin signaling, immune function, tumor microenvironment and cancer-related metabolic pathways.

Importantly, biological mechanisms and clinical outcomes must be evaluated separately. Evidence that exercise changes a biomarker does not automatically prove that it improves cancer survival.

Exercise oncology covers four main stages

1. Prevention

Physical activity and long-term health, including evidence concerning cancer risk reduction.

2. Prehabilitation

Improving physical capacity before surgery or other intensive cancer treatment.

3. Active treatment

Maintaining physical fitness, muscle strength, mobility and functional ability during treatment.

4. Rehabilitation and survivorship

Rebuilding physical capacity and supporting long-term health following treatment.

2. Why Exercise Matters in Cancer Care

Cancer treatment can affect physical function through multiple pathways. Chemotherapy may contribute to fatigue and peripheral neuropathy. Surgery can reduce mobility and muscle function. Hormonal therapy can affect bone and muscle health. Radiotherapy can contribute to local tissue changes and functional limitations.

Reduced physical activity can then create a cycle of deconditioning, weakness and further activity avoidance.

Six important areas of benefit

1. Muscle strength and physical function

Resistance training helps maintain or improve muscle strength and physical capacity. This is particularly relevant for patients at risk of sarcopenia or treatment-related deconditioning.

2. Cardiorespiratory fitness

Aerobic exercise can help maintain or improve cardiovascular and respiratory fitness during and after cancer treatment.

3. Cancer-related fatigue

Exercise is one of the interventions recommended in clinical guidelines for managing cancer-related fatigue. It can help patients improve their ability to perform everyday activities.

4. Psychological wellbeing

Structured physical activity may help improve mood, reduce anxiety and support psychological wellbeing.

5. Mobility and independence

Strength, balance and functional training can help patients maintain independence in daily activities, especially older adults and people recovering from intensive treatment.

6. Cardiometabolic health

Physical activity supports cardiovascular health, glucose regulation and overall metabolic health. These are particularly relevant to long-term survivorship.

What exercise has not yet established

Although observational research has associated physical activity with better cancer outcomes in certain populations, evidence is not sufficient to claim that prescribing exercise during active cancer treatment universally improves recurrence or overall survival.

The most established clinical benefits are related to fatigue, physical fitness, strength, functioning and selected quality-of-life outcomes.

3. Clinical Evidence: What Do the Guidelines Say?

Exercise oncology has progressed from a relatively specialized research field to an important component of supportive cancer care.

ASCO Exercise, Diet and Weight Management Guideline 2022

The American Society of Clinical Oncology reviewed randomized clinical trials and systematic reviews examining exercise, dietary interventions and weight management during cancer treatment.

Its key recommendation is that oncology providers should recommend regular aerobic and resistance exercise during active treatment with curative intent.

Reported benefits include:

Reduced cancer-related fatigue.
Preserved cardiorespiratory fitness.
Maintained or improved physical functioning.
Improved muscle strength.
Improvements in selected quality-of-life outcomes.
Possible reductions in anxiety and depression in some populations.

The guideline also recognizes preoperative exercise as a possible intervention for patients undergoing lung cancer surgery to reduce postoperative complications and length of hospitalization.

ASCO–SIO Cancer-Related Fatigue Guideline Update 2024

The joint ASCO and Society for Integrative Oncology guideline evaluated 113 randomized controlled trials involving interventions for cancer-related fatigue.

Exercise, cognitive behavioral therapy and mindfulness-based programs improved fatigue both during and after cancer treatment.

The guideline recommends:

Exercise during and after cancer treatment.
Cognitive behavioral therapy.
Mindfulness-based programs.
Tai chi or qigong at low to moderate intensity during treatment.

These recommendations are based on fatigue outcomes, not evidence that the interventions eliminate cancer.

ACSM International Exercise Oncology Roundtable

The 2019 international multidisciplinary roundtable provided a major foundation for exercise recommendations in cancer survivors.

It examined exercise prescriptions and outcomes including:

Cardiorespiratory fitness.
Muscle strength.
Fatigue.
Depression and anxiety.
Physical functioning.
Health-related quality of life.
Bone health and other treatment-related effects.

The consensus supports regular aerobic and resistance training to improve several cancer-related health outcomes.

4. The Two Foundations: Aerobic and Resistance Exercise

Most structured cancer exercise programs incorporate some combination of aerobic and resistance exercise, adjusted to individual needs and physical capacity.

A. Aerobic Exercise

Aerobic exercise involves continuous or intermittent activity that uses large muscle groups and increases cardiovascular and respiratory demand.

Examples include:

Walking.
Stationary cycling.
Swimming, where appropriate.
Low-impact aerobic exercise.
Selected dancing and movement activities.
Supervised treadmill exercise.

Potential benefits include improved cardiovascular fitness, reduced fatigue and better exercise tolerance.

B. Resistance Exercise

Resistance exercise challenges muscles against an external load or the individual's own body weight.

Examples include:

Chair sit-to-stand exercises.
Resistance-band training.
Light dumbbell exercises.
Machine-based resistance training.
Wall push-ups.
Modified squats and step exercises.

Resistance training is particularly relevant for preserving muscle strength and improving physical function.

C. Balance and Functional Training

Some patients, particularly older adults and those with peripheral neuropathy or muscle weakness, need balance and coordination training.

Examples include supervised standing balance, supported stepping and functional movement exercises.

These activities may help patients maintain everyday independence and reduce falls risk when appropriately prescribed.

D. Flexibility and Mobility

Range-of-motion exercises can help maintain joint mobility and address stiffness after surgery or radiotherapy.

Stretching should be comfortable and appropriate to the treated area, surgical restrictions and any tissue-related complications.

5. Understanding the FITT Exercise Prescription

Exercise programs are commonly planned using the FITT framework:

F – Frequency: How often the activity is performed.
I – Intensity: How challenging the activity is.
T – Time: How long each session lasts.
T – Type: The form of exercise selected.

General exercise benchmarks

Component	General research-informed benchmark	Practical interpretation
Aerobic frequency	At least 3 sessions per week in commonly studied survivor programs.	Begin with tolerable activity and distribute sessions across the week.
Aerobic intensity	Moderate intensity in many established exercise programs.	Activity should feel purposeful but manageable; speaking should generally remain possible.
Aerobic duration	Approximately 30 minutes in many studied sessions.	Shorter intervals are appropriate when fatigue or treatment effects limit endurance.
Resistance frequency	At least twice weekly in many survivor programs.	Target major muscle groups using individually appropriate resistance.
Resistance progression	Gradual progression according to strength and tolerance.	Begin with low loads, appropriate technique and adequate recovery.
Program duration	Many trials used structured programs lasting 8–12 weeks or longer.	Reassess progress and adjust throughout treatment and recovery.

These are research benchmarks, not a prescription for every person receiving cancer treatment. The patient's treatment phase, condition and medical risks determine the appropriate starting point.

Using the talk test

One simple way to estimate moderate intensity is the talk test:

Light activity: Breathing increases slightly, but conversation remains easy.
Moderate activity: Breathing becomes more noticeable, but talking remains possible.
Vigorous activity: Conversation becomes difficult because breathing is substantially increased.

Perceived exertion and symptoms may be more useful than heart-rate targets in some patients, particularly those taking medicines that alter heart rate or experiencing treatment-related cardiovascular effects.

A general long-term activity target

For cancer survivors who have completed treatment and are medically able, the American Cancer Society promotes gradually building toward:

150–300 minutes of moderate-intensity activity each week, or
75–150 minutes of vigorous-intensity activity, or an equivalent combination.
Muscle-strengthening activity at least twice weekly.

This is a long-term public-health target, not a mandatory starting goal for patients undergoing chemotherapy or recovering from major surgery.

American Cancer Society: Physical Activity When You Have Cancer →

Start with capacity, not an ideal target.

A patient who can manage five minutes of walking safely has a meaningful starting point. The objective is progressive, tolerable activity rather than forcing a predetermined exercise quota.

6. Muscle Preservation, Sarcopenia and Cancer

Muscle preservation deserves particular attention in oncology because muscle loss can occur alongside weight loss, reduced appetite, inactivity, systemic inflammation and treatment-related complications.

What is sarcopenia?

Sarcopenia is a progressive skeletal muscle disorder characterized by reduced muscle strength, with low muscle quantity or quality used to confirm the diagnosis.

In cancer patients, it may coexist with overweight or obesity, meaning that body weight alone can underestimate loss of muscle tissue.

Why muscle loss matters

Reduced strength and mobility.
Difficulty performing daily activities.
Lower physical exercise capacity.
Reduced independence.
Increased risk of falls in vulnerable patients.
Potentially poorer treatment tolerance and clinical outcomes in certain cancer settings.

Three approaches to protecting muscle

Resistance Training

Helps maintain or improve muscle strength and functional capacity.

Protein and Energy

Provides the nutritional support necessary for muscle maintenance and recovery.

Clinical Assessment

Identifies sarcopenia, cachexia, inadequate intake and other causes of physical decline.

Exercise should be combined with appropriate nutritional support. Resistance training without sufficient nutrition may be inadequate for patients with significant malnutrition.

See the companion guide:

Cancer Nutrition, Malnutrition and Cachexia: Protein and Muscle Preservation →

7. Prehabilitation: Preparing Before Cancer Treatment

Prehabilitation refers to interventions undertaken before a planned treatment or operation to improve the patient's functional capacity and readiness for the clinical procedure.

In oncology, this can include exercise, nutritional intervention, smoking cessation, psychological preparation and management of existing medical conditions.

Why prehabilitation matters

Patients may enter surgery or intensive cancer treatment with reduced physical fitness, nutritional deficits or pre-existing health conditions.

Improving these factors before treatment may help support recovery.

Prehabilitation components

Baseline exercise and mobility assessment.
Walking or aerobic conditioning.
Appropriate resistance training.
Nutritional optimization.
Smoking cessation.
Management of anemia and other medical conditions.
Psychological preparation and patient education.

Evidence in lung cancer surgery

The ASCO 2022 guideline identified evidence suggesting that preoperative exercise may reduce postoperative complications and length of hospital stay in patients undergoing lung cancer surgery.

The recommendation was conditional and the evidence quality was lower than that supporting exercise during active cancer treatment.

Prehabilitation should therefore be considered according to surgical urgency, available time and patient suitability.

Examples of prehabilitation activities

Supervised walking or cycling.
Breathing and respiratory exercises when appropriate.
Lower- and upper-body strengthening.
Mobility and functional training.
Protein and energy optimization.

8. Exercise During Active Cancer Treatment

Exercise does not necessarily need to stop during chemotherapy, radiotherapy or other cancer treatments.

Many patients can participate in appropriately modified physical activity, and the ASCO guideline supports aerobic and resistance exercise during active treatment with curative intent.

However, the program may need to change from week to week depending on symptoms, blood counts, treatment schedules and physical condition.

During chemotherapy

Possible priorities include maintaining strength, reducing deconditioning and managing fatigue.

Activity may need to be reduced during periods of significant nausea, infection, anemia or treatment-related weakness.

During radiotherapy

Exercise can help maintain mobility and physical function. The program may need to be modified when patients experience skin irritation, pain, fatigue or restricted movement around the treated area.

During immunotherapy

Exercise should be individualized according to the patient's overall condition and any immune-related adverse events.

Immune-related myocarditis, pneumonitis, myositis, severe colitis and endocrine complications require specific medical evaluation. New unexplained symptoms should not be dismissed as ordinary exercise fatigue.

After surgery

Early mobilization may be encouraged as part of postoperative care, but exercise progression must respect wound healing, surgical restrictions and rehabilitation guidance.

Adjusting exercise around treatment cycles

Some patients feel stronger between treatment sessions, while others experience fluctuating symptoms throughout the cycle.

Practical adjustments may include:

Shortening sessions during periods of fatigue.
Reducing resistance when strength is temporarily impaired.
Using gentle mobility work when appropriate.
Allowing additional recovery time.
Returning gradually when symptoms improve.

9. Exercise and Cancer-Related Fatigue

Cancer-related fatigue is one of the most common symptoms experienced by patients during and after cancer treatment.

It is more than ordinary tiredness and may affect physical, mental and emotional functioning.

Common contributors

Cancer-related inflammation.
Chemotherapy and radiotherapy.
Anemia.
Sleep disturbance.
Pain and medication effects.
Depression and anxiety.
Endocrine and metabolic abnormalities.
Physical deconditioning.

Why exercise can help

Although it may seem counterintuitive to recommend physical activity to someone experiencing fatigue, appropriately prescribed exercise can improve physical capacity and help reduce cancer-related fatigue.

The relationship is not simply that exercise makes patients tired enough to sleep. It may improve conditioning, reduce deconditioning and support overall functional recovery.

Guideline-supported interventions

The 2024 ASCO–SIO guideline recommends several approaches:

Intervention	During cancer treatment	After treatment
Exercise	Recommended	Recommended
Cognitive behavioral therapy	Recommended	Recommended
Mindfulness-based programs	Recommended	Recommended
Tai chi or qigong	Recommended at low to moderate intensity	Evidence less conclusive for this specific outcome
Yoga	Evidence insufficient for a general recommendation during treatment	May be recommended for selected survivors
Acupressure	Evidence insufficient for a general recommendation during treatment	May be considered after treatment

10. Neuropathy, Balance and Mobility

Chemotherapy-induced peripheral neuropathy can cause numbness, tingling, burning, pain, loss of sensation and balance problems.

These symptoms can interfere with walking, everyday activity and safe exercise participation.

Exercise priorities

Balance assessment.
Supported standing exercises.
Functional strength training.
Safe walking on appropriate surfaces.
Footwear and falls-risk assessment.
Adapted resistance training.
Physiotherapy where necessary.

Patients with significant neuropathy should avoid activities with a high risk of falling until their balance and mobility have been assessed.

Exercise does not replace medical assessment of treatment-related neuropathy. Changes in symptoms should be reported to the oncology team.

11. Exercise in Patients With Bone Metastases

Bone metastases require specific consideration because affected bones can be structurally weakened and may have an increased risk of fracture.

This does not mean every patient with bone metastases must avoid all physical activity.

It means that exercise should be planned around the location, extent and structural risk of the lesions.

Important considerations

Identify affected bones and lesion characteristics.
Assess fracture risk.
Avoid high-impact movement when contraindicated.
Modify resistance exercises that load affected areas.
Consider balance and falls prevention.
Seek specialist guidance from oncology rehabilitation or physiotherapy teams.

Spinal metastases may require particular attention to loading, posture and movement restrictions. New severe back pain, weakness, numbness, walking difficulties or bladder or bowel changes require urgent medical assessment because spinal cord or cauda equina compression must be considered.

Important

Exercise prescriptions for patients with bone metastases should not be taken from generic fitness programs. A clinician familiar with the patient's imaging and fracture risk should guide the selection of safe movements and resistance levels.

12. Exercise and Lymphedema

Lymphedema can occur following lymph-node surgery or radiotherapy, particularly in breast, gynecological and other cancers affecting lymphatic drainage.

It may cause swelling, heaviness, tightness, discomfort and reduced limb function.

Can patients with lymphedema exercise?

Appropriately prescribed exercise can be undertaken by many patients at risk of or living with lymphedema.

For patients with breast cancer-related lymphedema, gradual progressive resistance training has been investigated and is generally considered safe when properly introduced and monitored.

Practical considerations

Begin with an appropriate baseline assessment.
Progress resistance gradually.
Monitor swelling, discomfort and limb symptoms.
Use compression garments according to specialist advice.
Maintain skin care and infection awareness.
Consult a certified lymphedema therapist where needed.

A sudden increase in swelling, redness, pain or fever requires medical evaluation because infection or another complication may be present.

13. Exercise in Older Adults Living With Cancer

Older patients may experience additional challenges from frailty, reduced muscle reserve, osteoporosis, falls, cardiovascular disease, multiple medications and treatment-related functional decline.

Exercise programs should therefore incorporate more than aerobic fitness and muscle strength.

New 2026 consensus development

A 2026 consensus statement on exercise recommendations for older adults living with and beyond cancer supports adapting established cancer exercise guidance while paying additional attention to functional mobility and balance.

Its recommendations include:

Avoiding inactivity.
Working toward approximately 30 minutes of moderate aerobic and/or resistance activity three times weekly, as tolerated.
Progressing towards approximately 150 minutes of moderate-to-vigorous aerobic activity per week where feasible.
Including resistance training at least twice weekly.
Incorporating balance exercises, especially where falls risk or frailty is present.

The balance recommendations include one or two sets of four to ten different balance exercises on at least three days per week, adapted to functional ability.

These are consensus-based goals rather than requirements for frail patients or those undergoing intensive treatment. Individual assessment remains essential.

Priorities for older cancer patients

Maintain independence in daily activities.
Preserve leg strength and walking ability.
Improve balance and coordination.
Reduce deconditioning.
Adapt exercise to cardiovascular and musculoskeletal limitations.
Include adequate nutritional and protein support.

14. Exercise in Advanced and Metastatic Cancer

Exercise can remain relevant even in advanced cancer, but its purpose and intensity may be different from those of exercise during curative treatment or survivorship.

In advanced disease, priorities often include maintaining mobility, reducing deconditioning, supporting independence and improving quality of life.

Possible approaches

Short, comfortable walks.
Chair-based movement.
Gentle resistance exercises.
Mobility and flexibility work.
Supported standing activities.
Breathing and relaxation exercises.
Physiotherapy for specific limitations.

Exercise should be reduced or modified according to symptoms, fatigue, disease progression and medical complications.

For patients near the end of life, comfort and personal goals take priority over fitness targets. Even small amounts of supported movement may be useful for some patients, while others may need rest and symptom-focused care.

15. Exercise and Nutrition: A Combined Strategy

Exercise and nutrition are complementary components of physical health.

Resistance training creates a stimulus for muscle adaptation, while adequate dietary energy and protein support recovery and tissue maintenance.

The three-part muscle preservation strategy

Movement

Aerobic exercise and appropriate daily movement help maintain physical capacity.

Resistance

Progressive strengthening helps maintain or improve muscle strength.

Nutrition

Adequate protein, calories and hydration support physical recovery and function.

For patients experiencing malnutrition or cachexia, exercise needs to be particularly carefully balanced against nutritional status and overall energy requirements.

A high-volume exercise program may be inappropriate for someone with severe weight loss, significant fatigue or progressive disease.

In such circumstances, a lower-energy-cost rehabilitation approach with individualized nutrition may be more appropriate.

16. Wearables and AI-Assisted Exercise Oncology

Digital health technology is creating new opportunities to monitor physical activity, functional status and recovery in people living with cancer.

Smartwatches, activity trackers and other wearable devices can provide useful information about movement patterns and selected physiological measurements.

Potential applications

Daily step counts and activity patterns.
Heart-rate trends.
Exercise session monitoring.
Sleep tracking.
Activity reduction during treatment cycles.
Remote exercise coaching.
Rehabilitation adherence.
Patient-reported fatigue and functional outcomes.

AI-assisted exercise and rehabilitation

Artificial intelligence may help identify patterns in wearable data and support more individualized rehabilitation programs.

Potential research applications include:

Detecting changes in daily physical activity.
Identifying possible deterioration in functional status.
Supporting remote exercise programs.
Combining activity data with patient-reported fatigue.
Identifying patients who may benefit from rehabilitation assessment.

However, consumer wearables are not diagnostic tools for cancer complications. Heart-rate variability, sleep scores and step counts cannot reliably determine whether a patient is medically fit to exercise.

AI-generated recommendations must be validated and supervised appropriately, particularly during chemotherapy, immunotherapy and advanced cancer.

17. Practical Exercise Framework for Cancer Patients

The following framework helps patients and caregivers discuss exercise with their oncology team.

Step 1: Establish a baseline

Current physical activity level.
Walking and mobility ability.
Muscle strength.
Fatigue and exercise tolerance.
Balance and falls history.
Existing cardiovascular and pulmonary conditions.
Relevant cancer-related complications.

Step 2: Identify medical restrictions

Consider:

Bone metastases and fracture risk.
Peripheral neuropathy.
Severe anemia.
Low platelet counts.
Neutropenia or active infection.
Recent surgery and healing restrictions.
Lymphedema.
Cardiac or pulmonary toxicity.

Step 3: Choose appropriate exercise

The program may combine walking, stationary cycling, resistance bands, chair exercises, balance work and mobility training.

Step 4: Begin at a manageable level

Shorter sessions, lower resistance and longer recovery periods may be appropriate when capacity is limited.

Step 5: Progress gradually

Increase duration, frequency or resistance only when the patient can tolerate the existing activity without unacceptable symptoms or recovery problems.

Step 6: Monitor and reassess

Review activity, strength, mobility, fatigue, treatment changes and adverse symptoms. Adjust the plan as the cancer journey evolves.

A simple example for discussion with the care team

Day	Example activity	Purpose
Monday	Short walking session and light resistance exercise	Aerobic movement and strengthening
Tuesday	Gentle mobility and balance exercises	Movement and coordination
Wednesday	Walking or stationary cycling	Cardiorespiratory activity
Thursday	Recovery and gentle stretching	Mobility and recovery
Friday	Walking and modified resistance exercise	Fitness and muscle strength
Saturday	Light recreational movement	Daily activity and wellbeing
Sunday	Rest or comfortable movement	Recovery according to symptoms

This is an illustrative structure, not an individualized exercise prescription. Frequency, intensity, duration and selection of exercises must be adapted to clinical condition and treatment requirements.

When should exercise be stopped?

Stop the session and seek appropriate medical assessment for new chest pain, severe or unusual breathlessness, fainting, new neurological symptoms, significant palpitations or sudden severe pain.

Patients with fever, acute illness, marked dizziness, uncontrolled vomiting or other significant treatment complications should not attempt to exercise through these symptoms.

Always follow the oncology team's instructions when blood counts are low or medical restrictions apply.

Exercise safety in oncology

A 2024 clinical review on risk stratification and exercise prescription in people with cancer highlights the need to consider anemia, thrombocytopenia, neutropenia, fracture risk, neurotoxicity, lymphedema, metastases and cardiac or pulmonary conditions.

These issues do not necessarily prohibit all physical activity. They may require modified programs, professional supervision or temporary restrictions.

18. Frequently Asked Questions

Should cancer patients exercise?

Many cancer patients benefit from appropriately tailored exercise. Clinical guidelines recommend aerobic and resistance exercise during active treatment with curative intent to reduce side effects and help preserve physical function, fitness and strength.

Can I exercise during chemotherapy?

Many patients can exercise during chemotherapy, but intensity and duration may need modification according to fatigue, blood counts, symptoms and treatment-related complications. Discuss your program with your care team.

Does exercise help cancer-related fatigue?

Yes. Exercise is recommended in the ASCO–SIO cancer-related fatigue guideline during and after treatment. Its benefits relate to fatigue and physical functioning, not proof of direct tumor elimination.

Is walking enough?

Walking is a useful starting point for many patients. However, a comprehensive program may also include resistance, balance and mobility training, depending on the patient's needs.

Should cancer patients lift weights?

Many patients can benefit from resistance training, but loads and exercises must be adapted to surgical restrictions, bone metastases, neuropathy, fracture risk and other medical considerations.

Can exercise prevent muscle wasting?

Appropriate resistance exercise can help maintain or improve strength. However, cancer cachexia is a complex metabolic syndrome, and exercise alone cannot reliably reverse it. Adequate nutrition and medical management are also important.

Can exercise improve cancer survival?

Physical activity is associated with better long-term outcomes in some observational studies and cancer populations. However, the evidence from exercise interventions during active treatment is not sufficient to claim a universal improvement in recurrence or survival.

Can patients with metastatic cancer exercise?

Yes, selected patients can participate in adapted physical activity. The program must account for disease burden, bone lesions, fatigue, pain, medical stability and individual treatment goals.

Can patients with bone metastases exercise?

Many can, but the program must be designed around lesion location, fracture risk and the patient's physical condition. Exercises that place excessive stress on affected bones may need to be avoided.

What is prehabilitation?

Prehabilitation involves improving physical, nutritional and psychological readiness before planned cancer treatment or surgery. It may include aerobic activity, resistance training, nutritional optimization and other supportive interventions.

What is the best exercise for cancer patients?

There is no single best exercise for everyone. Walking, cycling, resistance training, mobility work and balance exercises have different purposes. An appropriate combination depends on the cancer and the patient's physical condition.

Should older cancer patients do balance exercises?

Yes, when appropriate. Balance and functional training are particularly relevant for older patients, people with frailty and those experiencing neuropathy or mobility limitations.

Do smartwatches help monitor exercise during cancer treatment?

Wearables can help track activity trends, heart rate and sleep, but they cannot replace medical assessment. Abnormal readings or symptoms should be discussed with the healthcare team.

Our Perspective: Exercise Is Part of Cancer Care

Exercise should no longer be considered an optional wellness activity that patients only return to after completing cancer treatment.

For many patients, appropriate physical activity can be part of the treatment journey itself, helping preserve muscle strength, cardiovascular fitness, physical function and independence.

However, exercise oncology is not about pushing every patient towards the same fitness target. It is about understanding the individual's condition and finding a sustainable level of activity that is appropriate to their treatment and physical capacity.

When combined with individualized nutrition, symptom management and rehabilitation, exercise becomes an important part of whole-person cancer care.

Move safely. Preserve muscle. Maintain function. Support recovery. Integrate exercise into evidence-based cancer care.

Medical Disclaimer

This resource is for education and research purposes only. It does not provide individualized exercise prescriptions, medical diagnosis or treatment recommendations.

Exercise during cancer treatment requires consideration of the patient's cancer diagnosis, treatment, blood counts, cardiovascular health, bone metastases, neuropathy, surgical restrictions and other medical conditions.

Patients should consult their oncology team, physiotherapist or qualified cancer exercise professional before starting or substantially changing an exercise program.

Do not exercise through chest pain, severe breathlessness, fainting, acute illness or other significant warning symptoms.

Exercise complements conventional cancer treatment. It does not replace established anticancer therapies.
