As an oncologist, I have had countless discussions with patients about the best ways to manage their overall health during cancer treatment. One of the most important conversations we often have is about the role of exercise in cancer care. Many patients are surprised when I recommend staying active during their treatment because they often expect rest to be the primary focus. However, the relationship between cancer and exercise is a powerful one, and the benefits of staying active can be significant for both physical and emotional well-being.
In this blog, I want to explore how exercise can help patients navigate the challenges of cancer treatment and recovery, while also providing some practical tips on how to incorporate activity safely into their daily routines.
The Science Behind Cancer and Exercise
The connection between cancer and exercise has been the subject of numerous studies, and the results are overwhelmingly positive. While every individual’s experience with cancer is different, research shows that exercise can benefit most patients by improving overall health, reducing treatment side effects, and even enhancing the effectiveness of certain therapies. Exercise does not have to be intense to make a difference—gentle activities like walking, yoga, or stretching can still offer significant benefits.
Here are some of the key ways that exercise can help during cancer treatment and recovery:
1. Improving Energy Levels
One of the most common side effects of cancer treatment is fatigue, which can make the idea of exercise seem impossible. However, counterintuitively, regular physical activity has been shown to actually increase energy levels over time. Exercise helps combat the tiredness associated with cancer treatment by boosting circulation and oxygen levels, improving muscle strength, and enhancing stamina. While it’s important to listen to your body and not overdo it, even short, gentle activities can make a big difference in combating fatigue.
2. Reducing Treatment Side Effects
Exercise has been shown to alleviate many of the common side effects of cancer treatments, such as chemotherapy or radiation. Physical activity can reduce nausea, improve digestion, and help alleviate constipation, which is a common issue for patients undergoing chemotherapy. Additionally, regular exercise helps prevent muscle loss and can improve joint mobility, reducing stiffness that may occur during long periods of inactivity.
Patients dealing with side effects like neuropathy (nerve damage that can cause numbness or tingling in the hands and feet) may find that gentle stretching and movement can help maintain circulation and muscle control. Cancer and exercise work together to enhance the body’s ability to cope with treatment.
3. Boosting Immune Function
Our immune systems are our first line of defense against illnesses, and cancer treatments can weaken this vital system. Exercise has been shown to support immune function by promoting circulation, which helps white blood cells move throughout the body more effectively. This increase in circulation can make the immune system more efficient at fighting infections or other health threats.
4. Supporting Mental Health
A cancer diagnosis can take an emotional toll, often leading to anxiety, depression, or stress. Staying physically active is one of the best ways to protect mental health during this challenging time. Physical activity releases endorphins—chemicals in the brain that help improve mood and reduce feelings of stress. For many patients, taking a short walk outside or practicing yoga provides a mental break and a sense of calm during an otherwise overwhelming period.
By maintaining some level of physical activity, patients often report feeling more in control of their bodies and their health. This sense of empowerment can make a significant difference in their emotional resilience as they undergo treatment.
5. Enhancing Recovery and Reducing Recurrence
The benefits of cancer and exercise extend beyond the immediate treatment phase. Regular exercise during and after treatment has been linked to better long-term outcomes, including faster recovery and lower recurrence rates. Studies show that cancer survivors who maintain a physically active lifestyle have a reduced risk of their cancer returning. Exercise helps regulate hormones like insulin and estrogen, which can play a role in the development and recurrence of certain types of cancer.
In some cases, being physically active may also improve the effectiveness of cancer treatments like chemotherapy or radiation. By increasing blood flow and oxygenation, exercise can enhance the delivery of drugs or radiation to the tumor site.
Tailoring Exercise to Your Individual Needs
While cancer and exercise offer numerous benefits, it’s important to recognize that not all patients are the same, and exercise routines should be tailored to individual needs and abilities. Here are some tips to safely incorporate exercise into your cancer treatment plan:
1. Consult with Your Healthcare Team
Before starting any new exercise routine, it’s crucial to speak with your oncologist or healthcare team. They can help assess your overall health, the type of cancer you have, and any treatment-related side effects to ensure that your exercise plan is safe and beneficial for you. They can also recommend specific activities based on your treatment schedule, energy levels, and physical limitations.
2. Start Slowly
If you haven’t been active before or if you’re feeling particularly fatigued, start with gentle activities. Walking is a great way to begin—start with 10-minute sessions, and gradually increase the time as your energy allows. Yoga and stretching exercises are also gentle options that improve flexibility and circulation without overtaxing the body.
3. Stay Consistent but Flexible
Consistency is key when it comes to exercise, but it’s important to listen to your body and adjust your routine as needed. Some days may be harder than others, and it’s okay to modify your activities based on how you’re feeling. Aim for regular activity, but remember that rest is also an essential part of your recovery.
4. Mix in Strength Training
In addition to cardio exercises like walking or cycling, incorporating strength training can help prevent muscle loss and improve bone health. Light weightlifting or resistance exercises can be tailored to your ability level and can help rebuild strength that might be lost during treatment.
5. Include Mind-Body Practices
Mind-body exercises, such as yoga, tai chi, or meditation, offer the dual benefits of physical activity and mental relaxation. These practices focus on breathing, mindfulness, and gentle movement, which can help ease stress while improving flexibility and balance.
Supporting Your Loved Ones Through Exercise
If you’re a caregiver or loved one of someone undergoing cancer treatment, encourage them to stay active, but also offer support. Joining them for a walk or a yoga class can make the experience more enjoyable and motivate them to keep moving. Exercising together also provides a valuable opportunity to bond and support their emotional well-being during this difficult time.
Conclusion: The Power of Staying Active
The connection between cancer and exercise is undeniable. Staying active during and after cancer treatment can improve both physical and emotional health, reduce side effects, and support faster recovery.
Remember, exercise doesn’t have to be strenuous to be effective. It’s about finding the right balance for your body, listening to your limits, and taking small steps toward better health. By incorporating regular exercise into your routine, you can take control of your well-being and enhance your journey toward healing.
