Sport and cancer: how to stay active during and after treatments
Exercising during or after cancer is not only possible, but is also strongly recommended.
Appropriate physical activity improves tolerance to treatments, helps to regain energy and plays an important role in preventing recurrences.
Laboratoire RENASCOR, committed alongside patients at every stage of their recovery, explains why and how to move safely.
The benefits of exercise during cancer
Contrary to common belief, practicing physical activity during chemotherapy or radiotherapy does not exhaust you more — on the contrary, it reduces the fatigue related to treatments.
Benefits include:
-
Improved tolerance to treatment side effects.
-
Reduced fatigue and some pain.
-
Muscle and joint strengthening to preserve mobility.
-
Reduced stress and anxiety.
-
Reduced risk of recurrence and improved life expectancy.
Key point: physical activity acts as a true therapeutic support, on the same level as good nutrition or restorative sleep.
Which sport to choose during cancer?
There is no single “best” sport universally, but rather the activity that suits you depending on your health, your wishes and your physical abilities.
The essential thing is to choose a sport that is adapted and supervised.
Some ideas:
-
Gentle walking or Nordic walking.
-
Stationary bike.
-
Adapted Yoga or Pilates.
-
Gentle swimming.
-
Light strengthening exercises with resistance bands.
Tip: favor consistency over intensity. Positive effects generally appear between 6 and 12 weeks.
How often should you exercise?
To obtain a real benefit :
-
2 to 3 sessions per week, spaced at least 24 hours apart to give the body time to recover.
-
Each session can last 30 to 45 minutes depending on your energy that day.
-
Listen to your body: if fatigue is too great, favor a shorter but regular session.
The importance of being supported
Do not start alone. Supervision by a professional trained in Adapted Physical Activity (APA) is essential.
Several organizations can support you :
-

-
Siel Bleu – www.sielbleu.org
-
Programme Activ – Institut Curie – www.curie.fr
-

-
Post-cancer thermal spa treatments (Brides-les-Bains, etc.)
After the illness: stay active for life
Exercise doesn't stop once treatments are finished.
Continuing to move helps you to:
-
Maintain your endurance and muscle mass.
-
Reduce the risk of recurrence.
-
Improve your quality of life in the long term.
Doing daily exercise, even at moderate intensity, is one of the best investments you can make for your health.
In summary
Exercise during and after cancer is a powerful ally: it improves mood, physical fitness and tolerance to treatments, while supporting recovery.
With proper supervision and a regular routine, physical activity becomes a tool for rebuilding, on the same level as medical care.
