Managing Stress and Fatigue During and After Cancer Treatment
By Sarah Tirimacco, Doctor of Chiropractic & Managing Member at Pinnacle Hill Chiropractic
A cancer diagnosis can affect nearly every part of daily life. For those navigating breast or gynecologic cancer, appointments, treatments, changes in routine, uncertainty about the future, and the physical and emotional effects of cancer can all take a toll on energy and well-being.
Stress and fatigue are common during cancer treatment and may continue after treatment ends. In fact, the National Cancer Institute (NCI) reports that more than 80% of people receiving chemotherapy or radiation therapy experience fatigue. For some cancer survivors, fatigue can persist for months or even years.
While there is no single solution for cancer-related fatigue or the stress that can accompany a cancer diagnosis, research has identified strategies that may help.
Cancer-Related Fatigue Is More Than Feeling Tired
Cancer-related fatigue can feel different from the exhaustion you might experience after a long day. According to the NCI, it is not always relieved by sleep or rest and may occur even after very little activity. It can affect you physically, mentally, and emotionally, causing exhaustion, difficulty concentrating, or a lack of energy for usual activities.
Fatigue can occur before, during, or after treatment. Chemotherapy, radiation, surgery, immunotherapy, and other treatments may contribute, as can pain, anemia, sleep problems, nutrition changes, medications, and emotional distress.
Because many factors may be involved, managing fatigue often requires looking at several areas of your health and daily routine.
- Prioritize Where Your Energy Goes
When energy is limited, deciding where to spend it can help. The American Cancer Society recommends prioritizing activities that are most important to you and, when possible, doing them during the time of day when you typically have the most energy.
Try separating daily activities into three categories: things that need to happen, things you would like to happen, and things that can wait. Ask yourself, “What matters most today?” rather than measuring your day against what you could accomplish before your diagnosis or treatment.
Accepting help can also conserve energy. Allowing someone to bring dinner, drive you to an appointment, walk the dog, or run an errand may leave more energy for what matters most to you.
- Keep Moving—But Adjust Your Expectations
When you’re exhausted, exercise may sound like the last thing you want to do. However, physical activity is one of the evidence-supported strategies for managing cancer-related fatigue.
Both the NCI and American Cancer Society recommend appropriate physical activity during and after cancer treatment. Depending on your health and treatment, this could include walking, gentle mobility exercises, yoga, or gradually returning to activities you enjoy.
Most importantly, meet yourself where you are. Some days, a 20-minute walk may feel manageable. On another day, five minutes of movement around the house may be more appropriate. Both count.
Talk with your healthcare team before starting or changing an exercise program if you are undergoing treatment, recovering from surgery, or experiencing significant weakness, balance problems, or other symptoms that may require additional precautions.
- Balance Rest with Activity
Rest is important during treatment and recovery, but more time in bed doesn’t always mean more energy. The NCI and American Cancer Society recommend balancing rest with activity because long periods of inactivity can contribute to loss of strength and function, while too much daytime sleep may interfere with nighttime sleep.
Consider planning intentional periods of rest throughout your day. A brief nap, quiet time, breathing exercises, reading, or listening to music can provide opportunities to recharge.
Pay attention to patterns in your energy, too. If mornings tend to be your best time, consider scheduling more demanding activities then and protecting part of your afternoon for recovery.
- Recognize the Connection Between Stress and Fatigue
Cancer brings more than physical challenges. Concerns about treatment, work, family, finances, relationships, body changes, recurrence, and the future can create a significant emotional load.
The NCI notes that high levels of distress can contribute to fatigue, difficulty sleeping, and appetite changes. At the same time, persistent exhaustion may make it harder to cope with stress.
You don’t need to eliminate stress entirely. Instead, look for realistic ways to give your mind and body opportunities to recover. Meditation, breathing exercises, yoga, time outdoors, journaling, music, counseling, and cancer support groups are some options. The best strategy is often one that feels accessible enough to become part of your life.
- Support Healthy Sleep
Cancer and its treatment can make sleep complicated. Stress, pain, medications, hormonal changes, hot flashes, and other treatment side effects may interfere with sleep. Susan G. Komen notes that fatigue and insomnia are common during breast cancer treatment and may continue afterward.
Try maintaining relatively consistent sleep and wake times, keeping your bedroom dark and comfortable, and creating a calming bedtime routine. Reducing screen use and caffeine before bed and getting physical activity and natural light during the day may also support healthy sleep.
If sleep problems are persistent or affecting your quality of life, talk with your healthcare team. Underlying contributors may be treatable, and approaches such as cognitive behavioral therapy may help some people with insomnia.
- Fuel and Hydrate Your Body
Cancer and its treatments can affect appetite, taste, digestion, nausea, and your ability or desire to prepare meals. Rather than aiming for a “perfect” diet, focus on giving your body the nutrition and hydration it needs as consistently as possible.
The NCI recommends speaking with a registered dietitian when nutrition is contributing to fatigue. Smaller, more frequent meals may also be easier during treatment.
If nausea, appetite changes, swallowing difficulties, gastrointestinal symptoms, or weight changes make eating difficult, let your oncology team know. An oncology dietitian can help develop strategies that fit your needs and treatment plan.
- Talk About Fatigue with Your Healthcare Team
Fatigue may be common during cancer treatment, but that doesn’t mean you simply have to live with it. Your healthcare team can evaluate potential contributors such as anemia, pain, medications, sleep difficulties, nutrition, emotional health, and other medical conditions.
Consider tracking your energy for several days, including when fatigue is best or worst, how you’re sleeping, and how much it interferes with daily life. This information can help your healthcare team better understand what you’re experiencing.
Contact your healthcare team if fatigue is worsening or preventing you from completing basic daily activities. Seek urgent medical attention for symptoms such as severe shortness of breath at rest, confusion, significant dizziness, loss of balance, or falls.
Finding a New Rhythm
Your capacity may change from one day to the next during treatment and survivorship. Recovery isn’t always a straight line.
Choose the activities that matter most. Move when you’re able. Make room for rest. Accept help. Pay attention to sleep and nutrition. Stay connected to people who support you, and communicate with your healthcare team when something doesn’t feel right.
Managing stress and fatigue isn’t about doing everything perfectly. It’s about finding strategies that make your days more manageable while supporting your physical and emotional well-being during treatment, recovery, and beyond.
