Fatigue and Cancer: An Integrative Approach - CancerChoices



Fatigue

Fatigue, whether from cancer or from the demands of caregiving, can impair your quality of life, but several therapies and practices can provide relief.

Fatigue at a glance

Fatigue goes beyond feeling tired from missing a night of sleep. Fatigue can keep you not only from recreational activities you enjoy but also from working or providing care for children, elders, pets, or others in your life. Fatigue can keep you from taking care of your own basic needs, such as preparing meals, overseeing your well-being, and paying bills. It can also interfere with your ability to socialize with the people you need for support, isolating you when you most need help and companionship. Cancer-related fatigue can impair your quality of life, but several therapies can provide relief.

Fatigue: overview

What is fatigue? 

Fatigue as a symptom of cancer or side effect of treatment goes well beyond simply feeling temporarily tired or worn out, such as from a sleepless night. Some describe it as “unexplained, persistent, and relapsing exhaustion,”1Fatigue and Exhaustion: Causes, Symptoms, and Treatment. Web MD. October 4, 2023. Viewed June 13, 2024. and it “lasts longer, is more profound and isn’t relieved by rest.”2Mayo Clinic staff. Fatigue. Mayo Clinic. December 2, 2020. Viewed May 11, 2022. 

Fatigue and cancer

Cancer-related fatigue (CRF) is one of the most common side effects of having cancer and receiving cancer treatment. Physical, mental, and emotional challenges all feed into CRF. CRF can affect all facets of a person’s quality of life.3Bower JE, Lacchetti C et al. Management of fatigue in adult survivors of cancer: ASCO-Society for Integrative Oncology guideline update. Journal of Clinical Oncology. 2024 May 16:JCO2400541. 

Fatigue is linked to pain, which may work in both directions—each can trigger and enhance the other.4Theobald DE. Cancer pain, fatigue, distress, and insomnia in cancer patients. Clinical Cornerstone. 2004;6 Suppl 1D:S15-21. If you are experiencing pain in addition to fatigue, we recommend you visit our Pain › handbook to explore therapies and practices that may help with your pain, which may also help reduce your fatigue.

In extreme cases, fatigue may cause a person with cancer to stop treatment. Managing fatigue may allow you to complete treatment to achieve its full benefits as well as maintain a higher quality of life. 

Fatigue is linked to lower immune function,5Levy SR, Herberman ML et al. Correlation of stress factors with sustained depression of natural killer cell activity and predicted prognosis in patients with breast cancer. Journal of Clinical Oncology. 1987 Mar;5(3):348-53. a body terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation and more factor linked to worse cancer outcomes.

Caregiver fatigue

Caregivers can also experience fatigue. Caregiver fatigue occurs when the caregiver feels physically, emotionally, and psychologically exhausted, often leading to a change in attitude. Some practices and approaches are recommended specifically for caregivers. Within our Caregiver Handbook, see the section Finding support for yourself › 

What can cause fatigue?

Many factors may trigger or worsen fatigue among people with cancer.

Top evidence-based practices and therapies for managing fatigue 

SIO-ASCO clinical practice guidelines recommendations

Society for Integrative Oncology and American Society for Clinical Oncology logos

In 2024, the Society for Integrative Oncology and the American Society of Clinical Oncology published Management of Fatigue in Adult Survivors of Cancer: ASCO–Society for Integrative Oncology Guideline Update ›

These recommendations are based on a rigorous review of a high level of evidence. Therapies are recommended in the guidelines for different phases of cancer treatment. Each of these therapies is also recommended in at least one other clinical practice guidelines.9Survivorship Care for Cancer-Related Late and Long-Term Effects. National Comprehensive Cancer Network Guidelines for Patients. 2024. Viewed June 4, 2024; Gowin K, Muminovic M et al, Mehta A. Integrative therapies in cancer care: an update on the guidelines.

Both during and after treatment

During treatment 

  • Tai chi or qigong are forms of mind-body exercise and meditation, practiced at a low to moderate intensity. See Tai Chi or Qigong › 
  • Psychoeducation about side effects, such as fatigue, may be offered in an oncology clinic to individuals before beginning treatment.11Marschall A. How psychoeducation is used in therapy. VeryWell Mind. May 22, 2023. Viewed June 4, 2024.
  • American ginseng, Panax quinquefolius, an herbal supplement used in traditional medicine and by naturopathic oncologists is recommended at 2,000 mg daily. See Ginseng (American) › from About Herbs. 

After treatment

Recommendation against use; should be avoided

The guidelines recommend against use of these therapies due to a lack of effect in clinical trials.

  • Wakefulness agents
  • L-carnitine 
  • Psychostimulants
  • Antidepressants

Other practices and therapies

We present approaches to reducing fatigue backed by modestsignificant effects in at least three small but well-designed randomized controlled trials (RCTs), or one or more well-designed, mid-sized clinical studies of reasonably good quality (RCTs or observational studies), or several small studies aggregated into a meta-analysis (this is the CancerChoices definition; other researchers and studies may define this differently), goodsignificant effects in one large or several mid-sized and well-designed clinical studies (randomized controlled trials (RCTs) with an appropriate placebo or other strong comparison control or observational studies that control for confounds) (this is the CancerChoices definition; other researchers and studies may define this differently), or strongconsistent, significant effects in several large (or at least one very large) well designed clinical studies or at least two meta-analyses of clinical studies of moderate or better quality (or one large meta-analysis) finding similar results (this is the CancerChoices definition; other researchers and studies may define this differently) evidence of effectiveness.

If your fatigue is a symptom of other medical conditions, you may need to seek treatment to address the cause of your fatigue to find relief.

Conventional treatment

Your doctor may be able to determine if any of the medical conditions or medications listed above (or others) may be causing your fatigue and recommend treatments, such as for insomnia or infection.

Lifestyle practices 

  • Eating Well: A diet, such as a Mediterranean diet, rich in fruits, vegetables, whole grains, and omega-3 fatty acids may lead to less fatigue. Including a colorful array of fruits and vegetables makes for a diet rich in polyphenols and antioxidants, which can contribute to less fatigue. Fasting or restricting calories before and/or after chemotherapy treatments may possibly lead to less fatigue.12Pole L, Hepp N. How can Eating Well help you? What the research says. CancerChoices. April 14, 2024. Eating well is recommended in one practice guideline for managing fatigue.13Survivorship Care for Cancer-Related Late and Long-Term Effects. National Comprehensive Cancer Network Guidelines for Patients. 2024. Viewed June 4, 2024. See Which foods to eat (and what to avoid) ›

Complementary therapies 

Supplements and natural products
  • Astragalus-based Chinese botanicals: People treated with astragalus-based Chinese botanical formulas showed substantially less fatigue during chemotherapy.14Williams M, Hepp N, Pole L. How can astragalus help you? What the research says. CancerChoices. May 10, 2024. See Traditional medicine and professionals ›
  • Melatonin is a hormone and supplement that regulates sleep cycles. People treated with melatonin during radio/chemotherapy have shown less fatigue. People with advanced metastatic cancer have also shown less weakness or lack of energy when treated with melatonin.15Hepp N. How can melatonin help you? What the research says. CancerChoices. May 29, 2024. See Melatonin: affordability and access ›
  • Mistletoe is a plant extract formulated for injections or infusions. People with cancer treated with mistletoe have shown less fatigue.16Hepp N. How can mistletoe help you? What the research says. CancerChoices. May 28, 2024. See Mistletoe: affordability and access ›
  • Vitamin C: intravenous use: People with cancer treated with intravenous vitamin C have shown less fatigue during conventional cancer treatment.17Hepp N, Pole L. How can intravenous vitamin C help you? What the research says. CancerChoices. April 12, 2024. See Vitamin C: Intravenous Use: affordability and access ›
Other complementary therapies

Recommendation against use; should be avoided

Two natural products have recommendations against use for fatigue during cancer treatment in a practice guideline due to a lack of effect in clinical trials.22Greenlee H, DuPont-Reyes MJ et al. Clinical practice guidelines on the evidence-based use of integrative therapies during and after breast cancer treatment. CA: A Cancer Journal for Clinicians. 2017 May 6;67(3):194-232 (this set of guidelines has been endorsed by the American Society of Clinical Oncology (ASCO): Lyman GH, Greenlee H et al.
