Restore depleted energy
A cancer diagnosis can often by accompanied by a chronic lack of energy. Cancer-related fatigue often comes as a result of both cancer itself and harsh, invasive treatments such as chemotherapy, surgery, and radiation. Lifestyle changes, alternative therapies, and exercise can all help restock depleted energy stores.
Cancer-related fatigue (CRF) is one of the most common chronic symptoms and side effects of many cancer treatments. Coping with this fatigue is important for improving quality of life—during treatment and beyond. Lifestyle changes, alternative health techniques, exercise and supplements can help increase energy and enjoyment.
CRF goes beyond the normal, everyday tiredness of doing too much or not getting adequate rest. Day-to-day activities seem overwhelming, while the level of fatigue is out of proportion to the activity or amount of energy exerted. The feelings of being tired, worn out, heavy or lacking energy go deep, and a good night’s sleep is not enough to restore depleted energy.
CRF is a double-barrelled attack. One, it is often a symptom of cancer itself. Two, it is caused or exacerbated by traditional cancer treatments including surgery, chemotherapy, radiation, bone marrow transplants and biological therapies.
Because the effects of cancer and its treatments are widespread, CRF often has multiple causes. Many cancer patients already experience tiredness from a battery of pre-treatment tests and the emotional stress of dealing with the diagnosis, so it’s no surprise fatigue worsens with treatment.
Studies looking at the role of treatment in CRF point to a variety of causes, including
Other common causes of CRF include
CRF’s effects are far-reaching, affecting many aspects of life, ranging from making everyday activities more difficult to affecting our ability to work, and from changing our self-perceptions to negatively impinging on our relationships with friends and family.
In short, CRF is not “just a little bit of tiredness.” It’s a real and potentially debilitating condition with huge short-term and sometimes long-term impacts on our quality of life.
Among the pervasive effects are
Although the numbers vary depending on the type of cancer, treatment and patient profile, according to the US National Cancer Institute, CRF affects between 14 and 96 per cent of patients undergoing cancer treatment, and between 19 and 82 per cent of patients post-treatment.
The good news is that the level of fatigue usually decreases after treatment is finished. The bad news is that for many patients some degree of fatigue can last for months or years. A number of studies have indicated that even 10 years after treatment up to 30 per cent of cancer survivors still suffer from fatigue, a greater proportion than the general population.
The older we are, the more advanced the cancer and the more treatments we receive, the more likely we’ll suffer from long-term fatigue. Plus, some long-term treatments such as tamoxifen also contribute to CRF.
When fatigue strikes, we don’t have to hide in bed with the covers over our heads. We can take action by paying attention to our body’s physical and emotional needs, making appropriate lifestyle changes, using complementary alternative medical practices and taking supplements.
Whether dealing with short-term or longer-term fatigue, the best advice is to listen to our bodies and give them what they need. That means
Talking to a therapist about the emotional side of cancer—stress, anxiety and depression—which can worsen fatigue, may also help. Join a cancer support group to find information and talk to others coping with CRF. Call the Cancer Council Helpline on 13 11 20 to find a local group.
Whether before, during or after traditional cancer treatments, a variety of CAM techniques may help relieve stress and decrease fatigue.
Researchers have looked at this trio of mind and body exercises. The results indicate that combining the physical aspects of movement, stretching, balance and controlled breathing with the more spiritual aspect of meditation helps lessen fatigue.
Meditation, hypnosis, relaxation therapies, biofeedback Other forms of mindfulness-based meditation lessen anxiety, stress and mood and sleep disturbances, all of which are factors in fatigue. Hypnosis, relaxation therapies and biofeedback also help combat side effects.
A 2012 study showed acupuncture can significantly reduce CRF, while other studies have documented its ability to reduce fatigue-causing nausea and vomiting. Reiki and gentle massage are also helpful.
While a number of herbs and supplements look promising for managing symptoms and side effects, more rigorous studies are needed. Be sure to check with your health care practitioner before taking any supplements.
We know exercise is good for us—physically, emotionally and mentally. Cancer doesn’t change that. In fact, decreased physical activity can cause fatigue.
Studies and clinical trials of breast cancer survivors who participated in moderate physical activity reported decreased fatigue as well as less pain, better appetite, ability to do more daily activities and a greater satisfaction with life— all of which feed back into increased energy. Recent studies point to similar findings for other types of cancers.
While any exercise is useful, a review of studies shows moderate to vigorous intensity offers the greatest value, with three to six hours a week as the optimal amount.
Consult a health care practitioner before starting, as specific rehabilitation needs depend on the treatment and type of cancer. Be aware of the following safety precautions.
