Introduction

This patient summary on anxiety is adapted from a summary written for health professionals by cancer experts. This and other credible information about cancer treatment, screening, prevention, supportive care, and ongoing clinical trials is available from the National Cancer Institute. Anxiety is a normal reaction to cancer, but it can interfere with a patient's quality of life and the ability to follow through with cancer therapy. This brief summary describes the causes and treatment of anxiety experienced by cancer patients. Anxiety that may arise after cancer therapy has been completed is also discussed in this summary.

Overview

Anxiety is a normal reaction to cancer. One may experience anxiety while undergoing a cancer screening test, waiting for test results, receiving a diagnosis of cancer, undergoing cancer treatment, or anticipating a recurrence of cancer. Anxiety associated with cancer may increase feelings of pain, interfere with one's ability to sleep, cause nausea and vomiting, and interfere with the patient's (and his or her family's) quality of life. If left untreated, severe anxiety may even shorten a patient's life.

Persons with cancer will find that their feelings of anxiety increase or decrease at different times. A patient may become more anxious as cancer spreads or treatment becomes more intense. The level of anxiety experienced by one person with cancer may differ from the anxiety experienced by another person. Most patients are able to reduce their anxiety by learning more about their cancer and the treatment they can expect to receive. For some patients, particularly those who have experienced episodes of intense anxiety before their cancer diagnosis, feelings of anxiety may become overwhelming and interfere with cancer treatment. Most patients who have not had an anxiety condition before their cancer diagnosis will not develop an anxiety disorder associated with cancer.

Intense anxiety associated with cancer treatment is more likely to occur in patients with a history of anxiety disorders and patients who are experiencing anxiety at the time of diagnosis. Anxiety may also be experienced by patients who are in severe pain, are disabled, have few friends or family members to care for them, have cancer that is not responding to treatment, or have a history of severe physical or emotional trauma. Central nervous system metastases and tumors in the lungs may create physical problems that cause anxiety. Many cancer medications and treatments can aggravate feelings of anxiety.

Contrary to what one might expect, patients with advanced cancer experience anxiety due not to fear of death, but more often from fear of uncontrolled pain, being left alone, or dependency on others. Many of these factors can be alleviated with treatment.

Description and Cause

Some persons may have already experienced intense anxiety in their life because of situations unrelated to their cancer. These anxiety conditions may recur or become aggravated by the stress of a cancer diagnosis. Patients may experience extreme fear, be unable to absorb information given to them by caregivers, or be unable to follow through with treatment. In order to plan treatment for a patient's anxiety, a doctor may ask the following questions about the patient's symptoms:

• Have you had any of the following symptoms since your cancer diagnosis or treatment? When do these symptoms occur (i.e., how many days prior to treatment, at night, or at no specific time) and how long do they last?
• Do you feel shaky, jittery, or nervous?
• Have you felt tense, fearful, or apprehensive?
• Have you had to avoid certain places or activities because of fear?
• Have you felt your heart pounding or racing?
• Have you had trouble catching your breath when nervous?
• Have you had any unjustified sweating or trembling?
• Have you felt a knot in your stomach?
• Have you felt like you have a lump in your throat?
• Do you find yourself pacing?
• Are you afraid to close your eyes at night for fear that you may die in your sleep?
• Do you worry about the next diagnostic test, or the results of it, weeks in advance?
• Have you suddenly had a fear of losing control or going crazy?
• Have you suddenly had a fear of dying?
• Do you often worry about when your pain will return and how bad it will get?
• Do you worry about whether you will be able to get your next dose of pain medication on time?
• Do you spend more time in bed than you should because you are afraid that the pain will intensify if you stand up or move about?
• Have you been confused or disoriented lately?

Anxiety disorder includes adjustment disorder, panic disorder, phobias, obsessive-compulsive disorder, post-traumatic stress disorder, generalized anxiety disorder, and anxiety disorder caused by other general medical conditions. Each of these is explained below.

Adjustment disorder includes behaviors or moods more extreme than expected in a reaction to a cancer diagnosis. Symptoms include severe nervousness, worry, jitteriness, and the inability to go to work, attend school, or be with other people. Adjustment disorder is more likely to occur in cancer patients during critical times of the disease. These include being tested for the disease, learning the diagnosis, and experiencing a relapse of the disease. Many cancer patients can achieve relief from adjustment disorder in several ways, including receiving reassurance from caregivers, exercising relaxation techniques, taking medication, and participating in support and education programs.

Patients with panic disorder experience intense anxiety. Patients may suffer shortness of breath, dizziness, rapid heart beat, trembling, profuse sweating, nausea, tingling sensations, or fears of "going crazy." Attacks may last for several minutes or several hours and are treated with medication. Symptoms of panic disorder may be very similar to other medical conditions.

Phobias are ongoing fears about or avoidance of a situation or object. People with phobias usually experience intense anxiety and avoid situations that may frighten them. Cancer patients may fear needles. They may also fear small spaces and avoid having tests in confined spaces, such as magnetic resonance imaging (MRI) scans.

A person with obsessive-compulsive disorder has persistent thoughts, ideas, or images (obsessions) that are accompanied by repetitive behaviors (compulsions). Patients with obsessive-compulsive disorder may be unable to follow through with cancer treatment because they are disabled by thoughts and behaviors that interfere with their ability to function normally. Obsessive-compulsive disorder is treated with medication and psychotherapy. Obsessive-compulsive disorder is rare in patients with cancer who did not have the disorder before being diagnosed with cancer.

The diagnosis of cancer may cause a person who has previously experienced a life-threatening event to relive the trauma associated with that event. Patients with cancer who have post-traumatic stress disorder may experience extreme anxiety before surgery, chemotherapy, painful medical procedures, or bandage changes. Post-traumatic stress disorder is treated with psychotherapy.

Patients with generalized anxiety disorder may experience extreme and constant anxiety or unrealistic worry. For example, patients with supportive family and friends may fear that no one will care for them. Patients may worry that they cannot pay for their treatment, although they have adequate financial resources and insurance. Generalized anxiety disorder may happen after a patient has been very depressed. A person who has generalized anxiety may feel irritable or restless, have tense muscles, shortness of breath, heart palpitations, sweating, dizziness, and be easily fatigued.

Patients with cancer may experience anxiety that is caused by other medical conditions. Patients who are experiencing severe pain feel anxious, and anxiety can increase pain. The sudden appearance of extreme anxiety may be a symptom of infection, pneumonia, or an imbalance in the body's chemistry. It may also occur before a heart attack or blood clot in the lung and be accompanied by chest pain or trouble breathing. A decrease in the amount of oxygen that the blood is able to carry may also make the patient feel as though he or she is suffocating; this can cause anxiety.

Anxiety is a direct or indirect side effect of some medications. Some medications can cause anxiety, while others may cause restlessness, agitation, depression, thoughts of suicide, irritability, or trembling.

Certain tumors may cause anxiety or produce symptoms that resemble anxiety and panic by creating chemical imbalances or shortness of breath.

See the following PDQ summaries for more information:

• Normal Adjustment and the Adjustment Disorders ¹
• Post-Traumatic Stress Disorder ²

Treatment

It may be difficult to distinguish between normal fears associated with cancer and abnormally severe fears that can be classified as an anxiety disorder. Treatment depends on how the anxiety is affecting daily life for the patient. Anxiety that is caused by pain or another medical condition, a specific type of tumor, or as a side effect of medication, is usually controlled by treating the underlying cause.

Treatment for anxiety begins by giving the patient adequate information and support. Developing coping strategies such as the patient viewing his or her cancer from the perspective of a problem to be solved, obtaining enough information in order to fully understand his or her disease and treatment options, and utilizing available resources and support systems, can help to relieve anxiety. Patients may benefit from other treatment options for anxiety, including: psychotherapy, group therapy, family therapy, participating in self-help groups, hypnosis, and relaxation techniques such as guided imagery (a form of focused concentration on mental images to assist in stress management), or biofeedback (a method of early detection of the symptoms of anxiety in order to take preventative action). Medications may be used alone or in combination with these techniques. Patients should not avoid anxiety-relieving medications for fear of becoming addicted. Their doctors will give them sufficient medication to alleviate the symptoms and decrease the amount of the drug as the symptoms diminish.

Studies show that antidepressants are effective in the treatment of anxiety disorders. Children and adolescents being treated with antidepressants, however, have an increased risk of suicidal thinking and behavior. See the Treatment ³ section of the PDQ summary on Depression ⁴ for more information.

Post-treatment Considerations

After cancer therapy has been completed, a cancer survivor may be faced with new anxieties. Survivors may experience anxiety when they return to work and are asked about their cancer experience, or when confronted with insurance-related problems. A survivor may fear subsequent follow-up examinations and diagnostic tests, or they may fear a recurrence of cancer. Survivors may experience anxiety due to changes in body image, sexual dysfunction, reproductive issues, or post-traumatic stress. Survivorship programs, support groups, counseling, and other resources are available to help people readjust to life after cancer.

See the following PDQ summaries for more information:

• Post-Traumatic Stress Disorder ²
• Sexuality and Reproductive Issues ⁵

About PDQ

PDQ is a comprehensive cancer database available on NCI's Web site.

PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site ⁷. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.

PDQ contains cancer information summaries.

The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.

The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.

Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.

PDQ also contains information on clinical trials.

A clinical trial is a study to answer a scientific question, such as whether one method of treating symptoms is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. Some patients have symptoms caused by cancer treatment or by the cancer itself. During supportive care clinical trials, information is collected about how well new ways to treat symptoms of cancer work. The trials also study side effects of treatment and problems that come up during or after treatment. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients who have symptoms related to cancer treatment may want to think about taking part in a clinical trial.

Listings of clinical trials are included in PDQ and are available online at NCI's Web site ¹⁰. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.

The way a person thinks about his or her body and how it looks to others.

A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissues and can spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.

Invasion and multiplication of germs in the body. Infections can occur in any part of the body and can spread throughout the body. The germs may be bacteria, viruses, yeast, or fungi. They can cause a fever and other problems, depending on where the infection occurs. When the body’s natural defense system is strong, it can often fight the germs and prevent infection. Some cancer treatments can weaken the natural defense system.

One of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body.

A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. Magnetic resonance imaging makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. Magnetic resonance imaging is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called MRI, nuclear magnetic resonance imaging, and NMRI.

Access the National Cancer Institute Web site at http://www.cancer.gov. Also called NCI.

A feeling of sickness or discomfort in the stomach that may come with an urge to vomit. Nausea is a side effect of some types of cancer therapy.

An anxiety disorder in which a person has intrusive ideas, thoughts, or images that occur repeatedly, and in which he or she feels driven to perform certain behaviors over and over again. For example, a person may worry all the time about germs and so will wash his or her hands over and over again. Having an obsessive-compulsive disorder may cause a person to have trouble carrying out daily activities.

A colorless, odorless gas. It is needed for animal and plant life. Oxygen that is breathed in enters the blood from the lungs and travels to the tissues.

A rapid or irregular heartbeat that a person can feel.

Sudden extreme anxiety or fear that may cause irrational thoughts or actions. Panic may include rapid heart rate, flushing (a hot, red face), sweating, and trouble breathing.

PDQ is an online database developed and maintained by the National Cancer Institute. Designed to make the most current, credible, and accurate cancer information available to health professionals and the public, PDQ contains peer-reviewed summaries on cancer treatment, screening, prevention, genetics, complementary and alternative medicine, and supportive care; a registry of cancer clinical trials from around the world; and directories of physicians, professionals who provide genetics services, and organizations that provide cancer care. Most of this information, and more specific information about PDQ, can be found on the NCI's Web site at http://www.cancer.gov/cancertopics/pdq. Also called Physician Data Query.

An extreme, irrational, fear of something that may cause a person to panic. Examples of common phobias include fear of spiders, flying in an airplane, elevators, heights, enclosed rooms, crowded public places, and embarrassing oneself in front of other people.

A severe inflammation of the lungs in which the alveoli (tiny air sacs) are filled with fluid. This may cause a decrease in the amount of oxygen that blood can absorb from air breathed into the lung. Pneumonia is usually caused by infection but may also be caused by radiation therapy, allergy, or irritation of lung tissue by inhaled substances. It may involve part or all of the lungs.

An anxiety disorder that develops in reaction to physical injury or severe mental or emotional distress, such as military combat, violent assault, natural disaster, or other life-threatening events. Having cancer may also lead to post-traumatic stress disorder. Symptoms interfere with day-to-day living and include reliving the event in nightmares or flashbacks; avoiding people, places, and things connected to the event; feeling alone and losing interest in daily activities; and having trouble concentrating and sleeping. Also called PTSD.

In medicine, action taken to decrease the chance of getting a disease or condition. For example, cancer prevention includes avoiding risk factors (such as smoking, obesity, lack of exercise, and radiation exposure) and increasing protective factors (such as getting regular physical activity, staying at a healthy weight, and having a healthy diet).

Used to prevent disease.

Treatment of mental, emotional, personality, and behavioral disorders using methods such as discussion, listening, and counseling. Also called talk therapy.

The overall enjoyment of life. Many clinical trials assess the effects of cancer and its treatment on the quality of life. These studies measure aspects of an individual’s sense of well-being and ability to carry out various activities.

To come back or to return.

Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body. Also called recurrent cancer.

The return of signs and symptoms of cancer after a period of improvement.

A method used to reduce tension and anxiety, and control pain.

The organs involved in producing offspring. In women, this system includes the ovaries, the fallopian tubes, the uterus (womb), the cervix, and the vagina (birth canal). In men, it includes the prostate, the testes, and the penis.

A picture of structures inside the body. Scans often used in diagnosing, staging, and monitoring disease include liver scans, bone scans, and computed tomography (CT) or computerized axial tomography (CAT) scans and magnetic resonance imaging (MRI) scans. In liver scanning and bone scanning, radioactive substances that are injected into the bloodstream collect in these organs. A scanner that detects the radiation is used to create pictures. In CT scanning, an x-ray machine linked to a computer is used to produce detailed pictures of organs inside the body. MRI scans use a large magnet connected to a computer to create pictures of areas inside the body.

Checking for disease when there are no symptoms. Since screening may find diseases at an early stage, there may be a better chance of curing the disease. Examples of cancer screening tests are the mammogram (breast), colonoscopy (colon), Pap smear (cervix), and PSA blood level and digital rectal exam (prostate). Screening can also include checking for a person’s risk of developing an inherited disease by doing a genetic test.

A problem that occurs when treatment affects healthy tissues or organs. Some common side effects of cancer treatment are fatigue, pain, nausea, vomiting, decreased blood cell counts, hair loss, and mouth sores.

An organ that is part of the digestive system. The stomach helps digest food by mixing it with digestive juices and churning it into a thin liquid.

The act of taking one's own life on purpose.

A group of people with similar disease who meet to discuss how better to cope with their disease and treatment.

Care given to improve the quality of life of patients who have a serious or life-threatening disease. The goal of supportive care is to prevent or treat as early as possible the symptoms of a disease, side effects caused by treatment of a disease, and psychological, social, and spiritual problems related to a disease or its treatment. Also called palliative care, comfort care, and symptom management.

A procedure to remove or repair a part of the body or to find out whether disease is present. An operation.

One who remains alive and continues to function after overcoming difficulties or life-threatening diseases like cancer.

In cancer, survivorship covers the physical, psychosocial, and economic issues of cancer, from diagnosis until the end of life. It includes issues related to the ability to get health care and follow-up treatment, late effects of treatment, second cancers, and quality of life.

An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

Treatment.

The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The throat is about 5 inches long, depending on body size. Also called the pharynx.

Injury to the body, or an event that causes long-lasting mental or emotional damage.

An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Tumors may be benign (not cancerous), or malignant (cancerous). Also called neoplasm.

To eject some or all of the contents of the stomach through the mouth.
