Anxiety - CancerChoices



Anxiety

Managing anxiety can help you maintain your daily activities and relationships and improve your quality of life. Reducing anxiety can boost your ability to make skillful choices about your care and cope with cancer treatment.

Anxiety at a glance

Anxiety—a general feeling of worry, nervousness, or unease—is common among people with cancer. Identifying and managing anxiety may be important parts of your cancer treatment plan. Triggers include fear, uncertainty, and conflict, and symptoms of anxiety include excessive worrying, restlessness, agitation, difficulty concentrating, and more. Anxiety is linked to worse cancer outcomes and body terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation and more factors important in cancer.

In addition to conventional treatments for anxiety, several self-care lifestyle practices and complementary therapies can help you manage anxiety. Those with the best evidence of effectiveness are listed here. 

Anxiety may also be a symptom of stress. If stress is contributing to your anxiety, managing your stress will be important in reducing it.

Anxiety: an overview

What is anxiety?

Anxiety is a common symptom among people with cancer.1Smith AB, Rutherford C et al. A systematic review of quantitative observational studies investigating psychological distress in testicular cancer survivors. Psycho-oncology. 2017 Nov 23; Jacobsen PB, Jim HS. Psychosocial interventions for anxiety and depression in adult cancer patients: achievements and challenges. CA A Cancer Journal for Clinicians. 2008 Jul-Aug;58(4):214-30. According to Cancer.Net, anxiety may be described as feeling nervous, “on edge”, or worried. A normal emotion, it alerts your body to respond to a threat.2Anxiety. American Cancer Society. February 1, 2020. Viewed June 27, 2024.

Intense and prolonged anxiety may interfere with your daily activities and relationships. Anxiety may make coping with cancer treatment more difficult and may also interfere with your ability to make choices about your care. Identifying and managing anxiety are important parts of your cancer treatment.3Anxiety. American Cancer Society. February 1, 2020. Viewed June 27, 2024.

Anxiety and cancer 

Anxiety is linked to higher risks of cancer,4Wang YH, Li JQ et al. Depression and anxiety in relation to cancer incidence and mortality: a systematic review and meta-analysis of cohort studies. Molecular Psychiatry. 2020 Jul;25(7):1487-1499. of recurrence,5Wang X, Wang N et al. Prognostic value of depression and anxiety on breast cancer recurrence and mortality: a systematic review and meta-analysis of 282,203 patients. Molecular Psychiatry. 2020 Dec;25(12):3186-3197. and of cancer-related death.6Wang YH, Li JQ et al. Depression and anxiety in relation to cancer incidence and mortality: a systematic review and meta-analysis of cohort studies. Molecular Psychiatry. 2020 Jul;25(7):1487-1499; Wang X, Wang N et al. Prognostic value of depression and anxiety on breast cancer recurrence and mortality: a systematic review and meta-analysis of 282,203 patients. Molecular Psychiatry. 2020 Dec;25(12):3186-3197. Anxiety is also linked to body terrain factors important in cancer, such as body weight,7Gariepy G, Nitka D, Schmitz N. The association between obesity and anxiety disorders in the population: a systematic review and meta-analysis. International Journal of Obesity (London). 2010 Mar;34(3):407-19; Amiri S, Behnezhad S. Obesity and anxiety symptoms: a systematic review and meta-analysis. Neuropsychiatrie. 2019 Jun;33(2):72-89. English. inflammation,8Costello H, Gould RL, Abrol E, Howard R. Systematic review and meta-analysis of the association between peripheral inflammatory cytokines and generalised anxiety disorder. BMJ Open. 2019 Jul 19;9(7):e027925; Abbott R, Whear R et al. Tumour necrosis factor-α inhibitor therapy in chronic physical illness: a systematic review and meta-analysis of the effect on depression and anxiety. Journal of Psychosomatic Research. 2015 Sep;79(3):175-84. and your microbiome.9Okubo R, Kinoshita T et al. Impact of chemotherapy on the association between fear of cancer recurrence and the gut microbiota in breast cancer survivors. Brain, Behavior, and Immunity. 2020 Mar;85:186-191; Paulsen JA, Ptacek TS et al. Gut microbiota composition associated with alterations in cardiorespiratory fitness and psychosocial outcomes among breast cancer survivors. Supportive Care in Cancer. 2017 May;25(5):1563-1570.

Anxiety is also linked to symptoms and side effects common with cancer: 

These links may be complex: anxiety may lead to these problems, or these problems may contribute to anxiety. Sometimes the links work in both directions, such as anxiety worsening pain and more pain worsening anxiety. Since we have good evidence of these links, managing your anxiety may be one step you can take to improve your well-being and treatment outcomes—and managing body terrain factors such as body weight, inflammation and your microbiome may ease anxiety.

What can cause or trigger anxiety?

If you are living with cancer, you may have fears and worries related to cancer, treatments, recurrence, and their impacts on you and your family. Any of these may trigger anxiety.16Anxiety. American Cancer Society. February 1, 2020. Viewed June 27, 2024; Hendriksen E, Williams E et al. Worried together: a qualitative study of shared anxiety in patients with metastatic non-small cell lung cancer and their family caregivers. Supportive Care in Cancer. 2015 Apr;23(4):1035-41; Meissner VH, Olze L et al. Fear of cancer recurrence and disease progression in long-term prostate cancer survivors after radical prostatectomy: a longitudinal study. Cancer. 2021 Nov 15;127(22):4287-4295; Tsao PA, Ross RD, Bohnert ASB, Mukherjee B, Caram MEV. Depression, anxiety, and patterns of mental health care among men with prostate cancer receiving androgen deprivation therapy. Oncologist. 2022 Apr 5;27(4):314-322.

Medical and emotional conditions

Obesity17Gariepy G, Nitka D, Schmitz N. The association between obesity and anxiety disorders in the population: a systematic review and meta-analysis. International Journal of Obesity (London). 2010 Mar;34(3):407-19; Amiri S, Behnezhad S. Obesity and anxiety symptoms: a systematic review and meta-analysis. Neuropsychiatrie. 2019 Jun;33(2):72-89. English. and alcohol use18Mosel S. Anxiety and alcohol: does drinking cause anxiety & panic attacks? American Addiction Centers. March 8, 2024. Viewed June 26, 2024. are each linked to increased risk of anxiety. For a person with obesity and/or alcohol use along with anxiety, the links could work in several ways. Obesity or alcohol use may increase risk of anxiety, but anxiety may also increase risk of obesity or alcohol use. Researchers suspect that the links work in both directions. This may mean that reducing either anxiety or obesity may lead to less of the other, and the same may be true for anxiety and alcohol use. 

People with cancer with poorer sleep quality have shown more anxiety.19Pole L, Hepp N. How can Sleeping Well help you? What the research says. CancerChoices. January 18, 2024. 

Your inability to take care of yourself and be mobile and independent at home or in your community20Chen ML, Chang HK, Yeh CH. Anxiety and depression in Taiwanese cancer patients with and without pain. Journal of Advanced Nursing. 2000 Oct;32(4):944-51. or fixating on worst-case outcomes (catastrophizing)21Fischer DJ, Villines D, Kim YO, Epstein JB, Wilkie DJ. Anxiety, depression, and pain: differences by primary cancer. Supportive Care in Cancer. 2010 Jul;18(7):801-10. may contribute to higher anxiety.

Medications and therapies

Some medications and natural products used during cancer treatment or for other conditions may trigger anxiety. Check the inserts with any prescription medications you use or ask your pharmacist if you have concerns. Some therapies that may trigger anxiety: 

Diet

Some foods are linked to an increased risk of anxiety, such as foods containing caffeine or a pro-inflammatory diet high in commercially baked goods, fried foods, and fatty meats and low in fruits and vegetables.23Pole L, Hepp N. How can Eating Well help you? What the research says. CancerChoices. April 14, 2024.

Noise

Exposure to traffic noise is linked to an increased risk for anxiety.24Hepp N, Williams M. Creating a Healing Environment. CancerChoices. February 22, 2024.

Risk factors for anxiety

You are more likely to experience anxiety if you have any of these risk factors:25Anxiety. American Cancer Society. February 1, 2020. Viewed June 26, 2024; Okuyama M, Takaishi O et al. Associations among gastroesophageal reflux disease, psychological stress, and sleep disturbances in Japanese adults. Scandinavian Journal of Gastroenterology. 2017 Jan;52(1):44-49. 

  • Previous diagnosis or family history of anxiety or depression
  • Lack of support from friends and family
  • Financial burdens
  • Gastroesophageal reflux disease (GERD)

What are the signs or symptoms of anxiety? 

Anxiety can be linked to any of these symptoms.26Julson E. Signs and Symptoms of Anxiety Disorders. Healthline. August 26, 2021. Viewed March 16, 2022; Raypole C. Physical Symptoms of Anxiety: How Does It Feel? Healthline. March 15, 2019. Viewed March 16, 2022.

Mental/emotional symptoms

  • Excessive worrying
  • Agitation
  • Restlessness
  • Difficulty concentrating
  • Irritability
  • Difficulty falling or staying asleep
  • Panic attacks
  • Avoiding social situations
  • Irrational fears

Physical symptoms

  • Muscle tension or pain 
  • Stomach pain, nausea, or digestive trouble
  • Headache
  • Weakness or fatigue
  • Rapid breathing or shortness of breath
  • Pounding heart or increased heart rate

Top evidence-based practices and therapies for managing anxiety 

We present approaches to reducing anxiety 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. Anxiety may also be a symptom of stress. If stress is contributing to your anxiety, managing your stress will be important in reducing it. If your anxiety is a symptom of other medical conditions, you may need to seek treatment to address the cause of your anxiety to find relief.

Seek professional help if needed. Diagnoses such as anxiety can require therapy from trained practitioners for management. We encourage you to explore the options available to you through your cancer team and other experts. Taking care of your mental health is as important as taking care of your physical health.

SIO-ASCO clinical practice guidelines recommendations

Society for Integrative Oncology and American Society for Clinical Oncology logos

In 2023, the Society for Integrative Oncology and the American Society of Clinical Oncology published Integrative Oncology Care of Symptoms of Anxiety and Depression in Adults With Cancer ›

These recommendations are based on a rigorous review of complementary therapies with a high level of evidence. Therapies are recommended in the guidelines for different phases of cancer treatment. Many of these therapies are also recommended in other clinical practice guidelines.27Gowin K, Muminovic M, Zick SM, Lee RT, Lacchetti C, Mehta A.

Other practices and therapies

Conventional therapies

Various prescription drugs may help manage anxiety. Ask your doctor for recommendations, but also ask about side effects from their use. Many of the lifestyle practices and complementary therapies described on this page have fewer side effects and sometimes may be as effective or more effective than prescription drugs, or may help reduce the amount of anti-anxiety medication you need to take. Safety note: Among people with pancreatic cancer, the anti-anxiety drug lorazepam increased a marker of inflammation (IL-6) and was linked to poorer survival.28Cornwell AC, Tisdale AA et al. Lorazepam stimulates IL6 production and is associated with poor survival outcomes in pancreatic cancer. Clinical Cancer Research. 2023 Aug 17:OF1-OF20.

Psychosocial therapies include cognitive behavioral therapy, relaxation training, imagery/visualization, psychoeducation, and behavioral approaches. These are recommended for managing anxiety among people with cancer in practice guidelines.((Andersen BL, Lacchetti C et al. Management of anxiety and depression in adult survivors of cancer: ASCO guideline update. Journal of Clinical Oncology. 2023 Jun 20;41(18):3426-3453; Deng GE, Rausch SM et al.

Supplements and natural products
  • Cannabis and cannabinoids (marijuana) are the buds or extracts from cannabis (marijuana) plants. People with non-cancer medical conditions have shown fewer anxiety symptoms when treated with pharmaceutical THC either with or without CBD, but insufficient evidence shows any benefit among people with cancer.34Hepp N, Pole L. How can cannabis and cannabinoids help you? What the research says. CancerChoices. May 10, 2024. See Cannabis and cannabinoids: affordability and access › Safety note: Cannabis use is linked to higher risk of some types of cancer and to worse response to immunotherapy among people with advanced cancer. Cannabis-derived therapies may also cause acute or prolonged psychotic states, distress, anxiety, sedation, and more.35Horn JR, Hansten PD. Drug interactions with marijuana. Pharmacy Times.

  • Melatonin is a hormone and supplement that regulates sleep cycles. Adults preparing for surgery or recovering from surgery (not specific to cancer) have shown less anxiety when treated with melatonin, comparable to results with benzodiazepines. No evidence to date shows an effect on anxiety among people with cancer.36Hepp N. How can melatonin help you? What the research says. CancerChoices. July 3, 2024.

Information for health professionals

A large RCT found that the mental health and dynamic referral for oncology (MHADRO) program may increase access to mental health care, lessen hospitalizations, and improve providers’ management of psychosocial needs, but does not appear to impact overall functioning over time.49O’Hea E, Kroll-Desrosiers A et al.
