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.

Glossary Terms

Cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment.

Feelings of fear, dread, and uneasiness that may occur as a reaction to stress. A person with anxiety may sweat, feel restless and tense, and have a rapid heart beat. Extreme anxiety that happens often over time may be a sign of an anxiety disorder.

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.

CNS. The brain and spinal cord. Also called CNS.

The process of identifying a disease, such as cancer, from its signs and symptoms.

In medicine, a disturbance of normal functioning of the mind or body. Disorders may be caused by genetic factors, disease, or trauma.

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

A legal drug that is used to prevent, treat, or relieve symptoms of a disease or abnormal condition.

The spread of cancer from one part of the body to another. A tumor formed by cells that have spread is called a “metastatic tumor” or a “metastasis.” The metastatic tumor contains cells that are like those in the original (primary) tumor. The plural form of metastasis is metastases (meh-TAS-tuh-SEEZ).

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.

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.

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.

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.

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.
