Cancer-Related Fatigue

What is Cancer-Related Fatigue?

Cancer-related fatigue is a distressing, persistent tiredness that is out of proportion to recent activity and is not relieved by rest. It is one of the most common symptoms in people with cancer, and in a large meta-analysis about 43% of patients reported fatigue, with about 71% when mild fatigue was counted.^[1]

Common symptoms

People describe heavy exhaustion, weak or heavy limbs, difficulty thinking clearly, low motivation, and a sense that ordinary tasks take far more effort than before.^[2] Fatigue often travels with poor sleep, low mood and pain.^[3]

• Tiredness that sleep or rest does not fix
• Trouble concentrating or remembering
• Reduced ability to do usual daily activities
• Fatigue that continues months or years after treatment ends^[2]

Causes and risk factors

Fatigue can come from the cancer itself, from treatments such as chemotherapy, radiation and surgery, or from related problems such as anemia, poor sleep, pain, low mood and other medical conditions.^[2] Researchers have linked it to inflammation, muscle and mitochondrial changes, and altered stress-hormone and brain signaling, but the exact cause is not known.^[4]

In the meta-analysis, severe fatigue was more common during active treatment than before treatment, more common after chemotherapy than after surgery or radiation, and more common in women.^[1]

How it is diagnosed and treated conventionally

Fatigue is identified through your own description and symptom scales, and your oncology team looks for treatable contributors. It is often under-diagnosed and under-treated.^[2] Patients report fatigue more often than doctors record it: in the meta-analysis, severe fatigue was reported far more often by patients than by physicians.^[1]

There is no single standard treatment, and exercise has the best support for preventing or reducing fatigue during and after treatment.^[2] The 2024 ASCO-Society for Integrative Oncology guideline, based on 113 trials, recommends exercise, cognitive behavioral therapy and mindfulness-based programs, and it advises against routine use of psychostimulants and against L-carnitine.^[5]

Why Cancer-Related Fatigue calls for a whole-person approach

Cancer-related fatigue rarely has one cause, so it is rarely fixed by one treatment. Biology, treatment effects, sleep, mood and physical activity can all contribute, and the guideline evidence reflects this: the best-supported approaches are mostly active and behavioral.^{[4, 5]}

Complementary care can sit alongside those approaches. Its role is to support comfort, sleep and stress, not to replace exercise or counseling.

Inflammation and body chemistry

Reviews describe raised inflammatory signals, mitochondrial and muscle changes, and disrupted stress-hormone (HPA axis) function in people with cancer-related fatigue.^[4] Whether treating these directly relieves fatigue is not established.

Sleep and stress

Fatigue is closely tied to sleep problems. In one trial of self-acupressure in ovarian cancer survivors, fatigue improved while sleep quality did not, which shows the two are related but separate targets.^[6]

Pain and mood

Fatigue is strongly correlated with pain in cancer survivors.^[3] A 2023 trial in people with advanced cancer found that acupuncture and massage improved pain, fatigue, insomnia and quality of life together.^[7]

Acupuncture for Cancer-Related Fatigue

What the research shows

Research suggests acupuncture and related methods may reduce cancer-related fatigue, but the studies are mixed in quality. A 2023 network meta-analysis of 34 trials with 2,632 participants found acupuncture treatments, especially combined with usual care, improved fatigue scores and had acceptable side effects, while calling for larger, higher-quality trials.^[8] An earlier meta-analysis of 7 trials with 804 participants found fatigue benefits for acupuncture and moxibustion despite several weaknesses in the studies.^[9] An overview of 51 systematic reviews listed fatigue among the symptoms acupuncture may help, but rated most of the reviews as low or very low methodological quality.^[10]

A secondary analysis of a US trial of 274 cancer survivors with chronic pain found fatigue fell by about 2 points on a 10-point scale with electroacupuncture or battlefield (ear) acupuncture, and the benefit lasted to 24 weeks. This was not a sham-controlled comparison of fatigue; the comparison was a waitlist.^[3]

Acupressure, which uses finger pressure instead of needles, has its own evidence. The 2024 ASCO guideline says acupressure and moxibustion may be recommended for fatigue after treatment is complete, and rated the evidence overall as low to moderate certainty.^[5] A 2026 trial in ovarian cancer survivors found that app-taught self-acupressure lowered fatigue compared with usual care, but the sham version also lowered it, and the two did not differ significantly.^[6]

Moxibustion, which warms points with burning mugwort, has mixed support. An infrared laser moxibustion trial in breast cancer survivors found less fatigue than waitlist control, but the difference from sham treatment at 6 weeks was not significant, although it was at 18 weeks, and the authors said the result needs confirming in larger trials.^[11] A network meta-analysis of 49 trials of non-drug therapies ranked massage first, followed by infrared laser and ginger moxibustion, though each therapy had few studies.^[12]

How acupuncture may work

How acupuncture might relieve fatigue is not known, and the studies above did not establish a mechanism. Cancer-related fatigue has been linked to inflammation and altered HPA-axis (stress-hormone) function, so an effect on those pathways is a possible but unproven explanation.^[4]

What treatment involves

Treatment uses fine, sterile, single-use needles placed at points chosen for you, usually left in for about 20 to 40 minutes. Trials gave about 10 to 12 sessions over several weeks, and we reassess after a short course of visits.^{[3, 11]}

Side effects are usually minor. In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000.^[13]

Tell the practitioner first if you have a low platelet count or low white blood cell count, a bleeding disorder, take blood thinners, have lymphedema in a limb, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Cancer-Related Fatigue

The Ayurvedic view

In Ayurveda, deep tiredness is traditionally linked to depleted ojas (vital essence) and to weakened digestive fire (agni) and tissues (dhatus), and cancer care is traditionally framed in terms of the doshas and the state of the tissues.^[14] These are traditional frameworks, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and is gentle in this setting:

• Diet and daily routine centered on regular warm meals, rest and steady sleep
• Light oil massage, if your oncology team agrees it is suitable for your skin and treatment area
• Individually prescribed herbs traditionally used for strength and stamina, such as ashwagandha, only after your oncology team has been informed and your cancer treatment and medicines have been reviewed

Panchakarma is not appropriate during pregnancy, acute illness, frailty or active chemotherapy, and in cancer care it should not be used without your oncology team's agreement.

What the research shows

The research on Ayurvedic treatment for cancer-related fatigue is very sparse. We found one open-label, non-randomized trial of 100 women with breast cancer, in which those who took ashwagandha root extract during chemotherapy reported less fatigue and better quality of life than those on chemotherapy alone. Its authors said a larger randomized trial is needed to confirm the findings.^[15] We found no systematic reviews of Ayurvedic treatments for cancer-related fatigue.

The rest of the Ayurvedic cancer literature we found is about traditional concepts of how disease develops, not tested fatigue treatments.^[14] Any benefit is therefore unproven, and Ayurvedic care here is offered for general support, sleep and stress, not as a proven fatigue treatment.

Herbal medicine for Cancer-Related Fatigue

Herbs and formulas that have been studied

Most research covers Chinese herbal formulas given with conventional care, and ginseng.^{[16, 17]} American ginseng (Panax quinquefolius) is the single herb that cancer-fatigue guidelines and reviews address.^{[5, 18]}

What the research shows

The evidence is limited. A review of 10 trials with 751 participants found Chinese herbal medicine appeared to relieve cancer-related fatigue, but the methodological quality was generally poor and the authors said the evidence was not enough for firm conclusions.^[16] For ginseng, the 2024 ASCO guideline says American ginseng may be recommended for people having cancer treatment, while noting that other dietary supplements did not improve fatigue.^[5] A systematic review of 10 ginseng studies in fatigue from chronic illness found modest evidence of benefit and a low risk of adverse events, and asked for stronger research.^[17] An earlier review rated ginseng as an option during active treatment and said no therapy could be definitively recommended.^[18]

Safety and herb-drug interactions

Herbs are active substances, and in people with cancer the cautions matter more. Case reports describe bleeding when warfarin was combined with herbs including ginseng, dang gui, dan shen, ginger and Boswellia.^[19] Tell us about every medicine you take, including chemotherapy, targeted therapy and blood thinners, and let your oncologist know about any herb before you start it.

In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or have surgery or radiation planned.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes cancer-related fatigue as deficiency of qi and blood, with weakness of the spleen. Researchers studying fatigue instead look at inflammation, mitochondrial energy production, and stress-hormone signaling.^[4]

Ayurveda's depleted ojas and weakened agni describe a state of low vitality and poor digestion and tissue nourishment. No study has shown that these concepts correspond to a specific biological process.

How this care fits with your medical care

For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care. Integrative care is added to, never substituted for, your oncology care, exercise, counseling and other evidence-based treatment. Do not stop or change prescribed treatment without your prescriber.

We do not diagnose the cause of fatigue or treat the cancer. Please bring your diagnosis, current treatment plan, a full list of medicines and supplements, and recent blood test results, including blood counts. Sudden or worsening fatigue should be reported to your oncology team.

When to seek urgent medical care

Fatigue that is sudden or severe can signal a problem that needs prompt assessment.

• Fever or chills, especially during chemotherapy
• Shortness of breath, chest pain or a racing heartbeat
• Fainting, severe dizziness or confusion
• Black stools, vomiting blood or unusual bleeding or bruising
• A swollen, painful leg
• Thoughts of ending your life (call or text 988, the Suicide and Crisis Lifeline)

If any of these occur, call 911 or go to the nearest emergency department.
